A New Species

A new species of the rare caridean genus Bresilia Calman, 1896, B. gibbosa, is described and illustrated on the basis of one ovigerous female and one male specimens collected from a shallow water marine cave in Okinawa Island, Ryukyu Islands, Japan. The new species is morphologically similar to B. antipodarum Bruce, 1990, B. briankensleyi Bruce, 2005, B. plumifera Bruce, 1990 and B. saldanhai Calado, Chevaldonné & dos Santos, 2004 in the strongly produced third abdominal tergite, the presence of a long epistomal process, and the presence of an exopodal flagellum on the first maxilliped, but is easily distinguished from all these allied species by the possession of movable spines in the dorsal rostral series and the angular, instead of spinose, pterygostomial margin of the carapace. This new species is the first representative of Bresiliidae from the North Pacific Ocean.

A New Species

A new species of Geodia is described from the North Pacific, collected in the summer of 2012 in the western Aleutian Islands. Geodia starki sp. nov. differs from all known species of Geodia by the possession of two categories of sterrasters and exceptionally large megascleres. The new species is compared with congeners of the North Pacific Ocean, Bering Sea, Arctic and the North Atlantic Oceans.

Unusual Type

Descriptions are given of two specimens of an unusual type of gonatid squid taken from the North Pacific Ocean. A discussion is made of their relationship to two existing genera, Gonatus and Berryteuthis, of the family Gonatidae, and a note is included on a North Pacific gonatid larva that may be a related earlier stage of these two specimens. Because of their size and condition, neither a new genus nor a new species is declared; however, on the basis of these records, it is suggested that there is a need for a redefinition of the genera of the family Gonatidae.

A New Species

A new species of deep-sea jellyfish, Crossota millsae (Cnidaria: Hydrozoa: Trachymedusae: Rhopalonematidae), is described from the North Pacific Ocean off California and Hawaii. Discrete depth sampling showed this species lives at depths below 1000 meters in both geographic locations. The species is more abundant off California than off Hawaii. The greatest population densities were found at ~2500 m off California and at ~1250 m off Hawaii. The burnt-tangerine color of the inner bell and bright pink to lavender color of the ring and radial canals, manubrium and gonads make living specimens of this species difficult to confuse with any other known species of hydromedusa. Sexually dimorphic differences in gonad morphology are evident. The pendant testes contained spermatids at various stages of spermatogenesis as observed using scanning electron microscopy. Ova develop directly into small medusae that reside subumbrellarly between the radial canals of the mother. Various developmental stages of C. millsae are shown in photographs and terminology of brooding and viviparity is discussed relative to other Cnidaria.

Two new species, Anonyx dalli and A. shoemakeri, closely allied to Anonyx validus Gurjanova are described. This group of three species is unique within the genus Anonyx in having short, broad, and poorly armed second uropods and an angular lower posterior margin on the side plate of peraeopod 4. These species are medium sized and confined to the North Pacific Ocean.
