Five new species of sandperch (Pinguipedidae: Parapercis) from southeast Asia and northwest Australia are described. Parapercis soliorta sp. nov., known from a single specimen acquired from the Iloilo Central Market, taken off Iloilo, Panay Island, Philippines, is readily distinguished by a unique colour pattern including a series of nine brilliant yellow-ringed red spots along the body and caudal fin. Parapercis rubricaudalis sp. nov. is described from 15 specimens trawled between Dampier and Cape Leveque, Western Australia in 70–119 m and a single specimen taken by aquarium fish collectors off Zambales, Luzon, Philippines. It has the posterior end of the opercular ridge armed with two or three strong spines, the margin of the preopercle, subopercle and interopercle strongly serrated, and colouration including six broad irregular orange to reddish bands across the body, and the pelvic fins and lower third of the caudal fin crimson-red. A complex of three closely related species, Parapercis flavipinna sp. nov. from the Philippines, Parapercis caudopellucida sp. nov. from Myanmar and Parapercis hoi sp. nov. from northwest Australia and the Philippines, share a series of six or seven irregular dusky double blotches along the sides, a series of small black spots along the base of the soft dorsal-fin, a pair of dusky blotches on the caudal-fin base, and mostly similar meristic values. Parapercis hoi sp. nov. is known from four specimens trawled off Broome, Western Australia, in 97–109 m and one specimen trawled in the Sibuyan Sea, Philippines, in 73–84 m. It may be distinguished from its two closest congeners by cycloid cheek scales, a distinctive anal-fin colouration, and lower pectoral-fin ray, gill raker and lateral-line scale counts. Parapercis caudopellucida sp. nov., trawled in 125–129 m in the Andaman Sea off southern Myanmar, is described from two specimens. It differs from its two closest congeners most obviously by cycloid cheek scales, caudal-fin colouration, and the presence of a dusky bar extending posteroventrally from the tip of the maxilla to the anteroventral edge of the preopercle. Parapercis flavipinna sp. nov. is described from two specimens acquired from the Iloilo Central Market, taken off Iloilo, Panay Island, in the Philippines. It is distinguished most readily by the presence of ctenoid cheek scales and colouration including rows of bright yellow spots on the anal and caudal fins, a yellow upper lip, a series of yellow streaks and spots on the head, and fleshy pectoral-fin base with a large dark purplish grey blotch followed by a distinct white-edged black bar.

A New Species

A new species of Gephyrocharax is described from the río Cascajales basin, a tributary of the río La Colorada, río Magdalena system, Colombia. The new species is distinguished from its congeners, exceptG. melanocheir, by the absence of an adipose fin in most specimens and by the possession of a lateral branched pectoral-fin ray in males with a distal fan-shaped structure with minute bony hooks and a dark blotch or a few scattered dark brown chromatophores along its branches. The new species differs from G.melanocheir by the absence of an intense black pigmentation at the base of the anterior five dorsal-fin rays, the number of vertebrae (40-41vs. 38-39), the frontals contacting each other anterior to the epiphyseal bar in adults (vs. the absence of contact), the posterior margin of the mesethmoid straight in its central portion (vs. strongly concave at this point), the pouch scale of mature males reaching caudal-fin ray 11 or the area between caudal-fin rays 11 and 12 (vs. reaching only to caudal-fin ray 10 or the area between caudal-fin rays 9 and 10), the number of minute terminal branches of the lateral branched pectoral-fin ray of mature males (60-88 vs. 28-54), a longer black lateral stripe along the body in males (reaching to the base of the caudal-fin rays vs. reaching the middle of the length of the caudal peduncle), and the snout length (28.3-31.8% HLvs. 22.2-28.0% HL). The diagnosis ofGephyrocharax is modified to include species with the adipose fin variably present

Light Organ

The Indo-Pacific apogonid genus Siphamia Weber 1909 is unique among cardinalfishes in having a bacterial biolumines-cent system and spinoid scales. Light is produced by luminous bacteria found in a small pocket connected to the gut in theabdominal cavity and in a sac on each side of the tip of the tongue. Siphamia consists of 23 small species many of whichare associated with invertebrates such as sea urchins, crown-of-thorns starfish and coral. Species of this genus fall intotwo main groups with different dark pigment pattern of the longitudinal translucent muscle acting as a light organ thatdiffuses light along the ventral edge of the body. The S. tubifer group, with a striated light organ, includes S. arabica, newspecies, from the Gulf of Oman; S. argentea from the Philippines and northern Western Australia; S. fraseri, new species,from New Caledonia, Tonga and Fiji; S. fuscolineata from the Marshall and Line islands; S. goreni, new species, from thesouthern Red Sea; S. guttulata from Darnley Island, Queensland; S. jebbi from the western Pacific, ranging from the Phil-ippines to Western Australia and east to the Caroline Islands, Fiji, and Tonga; S. majimai from the Ryukyu and Ogasawaraislands to northwestern Australia, ranging eastward to New Caledonia and Tonga; S. mossambica from the western IndianOcean; S. randalli, new species, from the Society and Cook islands; S. spinicola, new species, from Biak in eastern Indo-nesia, Papua New Guinea, Woleai Atoll, Vanuatu, New Caledonia and the Chesterfield Islands; S. stenotes, new species,from the Triton Bay area of Irian Jaya Barat Province of Indonesia; and S. tubifer ranging widely in the Indo-West Pacificfrom the Red Sea to Madagascar and east to Vanuatu. The S. tubulata group, with a dark-dotted light organ, includes S.brevilux, new species, from Papua New Guinea; S. cephalotes from southern Australia; S. corallicola from Indonesia, Sa-bah, and Timor Sea; S. cuneiceps from Western Australia and the east coast of Queensland; S. cyanophthalma, new species,from the Philippines, Palau, Indonesia, and Papua New Guinea; S. elongata from the Philippines and Brunei; S. fistulosafrom Java, Sumbawa and Komodo, Indonesia, and Brunei; S. roseigaster from Western Australia, ranging along the north-ern and eastern coast of Australia south to Sydney Harbour, New South Wales; S. senoui, new species, from the RyukyuIslands, Japan; and S. tubulata from the Papua Barat Province, Indonesia, south coast of Papua New Guinea, northern Western Australia and Queensland.

Onuxodon albometeori sp. nov. (Ophidiiformes: Carapidae) is described from a single specimen collected by commercial trawl off southwestern Taiwan. The new species is most similar to the Indo-Pacific species Onuxodon fowleri (Smith 1955), both process a remarkably slender body, and higher precaudal vertebral counts and a longer pectoral fin, although the two latter features are even more extreme in the former. Onuxodon albometeori sp. nov. is further distinguished from O. fowleri by its lesser body depth, greater head width, higher counts of precaudal vertebrae, and uniformly whitish coloration only on the posterior part of the body.

Heteroconger fugax sp. nov. (Congridae: Heterocongrinae) is described from a single specimen collected from Amami-oshima island, Japan. The new species is most similar to Heteroconger tomberua Castle & Randall 1999, known from Fiji and New Caledonia, in having a remarkably slender body with numerous small spots and a vertebral count close to 200. However, it can be distinguished from H. tomberua by the presence of a large distinct white blotch on the opercle; more numerous, dense spots over the entire head, including lips; ground color of body uniformly cream, without microscopic melanophores; numerous small conical cirri on the chin; and dorsal-fin origin located more posteriorly to appressed pectoral-fin tip. A survey of underwater photographs of Heteroconger on photographic database revealed H. fugax to be widely distributed in the northwestern Pacific Ocean, from the Ryukyu Archipelago to Borneo.

Theoretical Minimum

Whether a rigid body limits maneuverability depends on how maneuverability is defined. By the current definition, the minimum radius of the turn, a rigid-bodied, spotted boxfish Ostracion meleagris approaches maximum maneuverability, i.e. it can spin around with minimum turning radii near zero. The radius of the minimum space required to turn is an alternative measure of maneuverability. By this definition, O. meleagris is not very maneuverable. The observed space required by O. meleagris to turn is slightly greater than its theoretical minimum but much greater than that of highly flexible fish. Agility, the rate of turning, is related to maneuverability. The median- and pectoral-fin-powered turns of O. meleagris are slow relative to the body- and caudal-fin-powered turns of more flexible fish.

Hemiodus jatuarana, a new species of the Hemiodontidae from Oriximin , rio Trombetas, Amazon Basin, Brazil, is described. The new species can be readily distinguished from its congeners by the presence of a horizontally elongated dark spot on the caudal peduncle, and by the absence of any other dark pigmentation pattern on the body. Hemiodus jatuarana is readily separated from H. immaculatus, another species without dark pigmentation on the body, by having 25 27 epibranchial and 36 37 ceratobranchial gill rakers on the first branchial arch, and caudal-fin lobes without longitudinal stripes, vs. 14 16 and 21 25 gill rakers, and a conspicuous longitudinal stripe on each caudal-fin lobe in H. immaculatus. The new species is only known from its type-locality, where it cooccurs with H. immaculatus.
