A New Species

The name Nautilus clitellarius was given by J. de C. Sowerby to a Nautiloid from the Coal-measures, Coalbrookdale, Shropshire, and the description was accompanied by three figures, each representing a different specimen. In 1884 the species was included by Professor Hyatt in his new genus Ephippioceras. In 1891 Dr. A. H. Foord found a new species, Ephippioceras costatum, which was said to be “distinguished from E. clitellarium (to which it is, however, very closely related) by the character of the septa and by the surface ornaments. The septa in E. costatum do not form such an acute lobe upon the periphery as do those of E. clitellarium, and they are also a little wider apart in the former species than they are in the latter. Moreover, E. costatum is provided with prominent transverse costæ, which are strongest upon the sides of the shell where they swell out into heavy folds. These costæ are directed obliquely backwards, and cross the septa at an acute angle, passing across the periphery and forming a shallow sinus in the middle. None of the specimens in the British Museum have the test preserved, so that the ribbing has only been observed upon casts. The costæ are equally well developed upon the body-chamber and upon the septate part of the shell in the adult, but they were either very feeble or altogether absent in the young.” A re-examination of the specimens in the Museum collection shows that the separation of the two forms is quite justifiable.

A New Species

There has recently been presented1 to the British Museum collection an Ammonite from the Gault of Folkestone that seems to be worthy of a short note. It is represented in the accompanying figures. At first sight it appears to be a new species. The shell is nearly complete and exceedingly well preserved; there has evidently been another half whorl to the specimen (see Fig. a), but this, which apparently constituted the body-chamber, has been broken away, leaving at the anterior end of the specimen the surface of the last septum.

AbstractFour rare Pennsylvanian (Stark Shale: Pennsylvanian, Missourian [=Kasimovian]) coleoids from Nebraska and Iowa, which are preserved as flattened partial phragmocones and body chambers associated with three-dimensionally fossilized ink sacs, are herein described as Pabianiconus starkensis new genus new species, Nebraskaconus whitei new genus new species, and Starkites compressus new genus new species. One specimen that is missing most of the phragmocone, is provisionally assigned to Donovaniconus. The fossils are assigned to the Coleoidea because of the presence of ink-filled sacs in the body chamber region of the conch. Additionally, eight fragmented and flattened phragmocones and body-chamber clusters with similar morphologies, including some with ink fragments and arm hooks, are assigned to the Coleoidea, but are not named because of their fragmentary condition. On most of the eight specimens, the shell material is associated with other unidentified finely macerated material, which suggests these fossils are probably either ejectoid masses or coprolites from coleoid predators and/or scavengers. However, the new genera named above appear to have been deposited as complete animals, based on the presence of the ink-filled sacs that are in the body chambers. With their body chamber and phragmocone morphologies, these rare coleoid taxa provide valuable information about conch variability within the Carboniferous evolutionary radiation of coleoids.

A New Species

A new genus of Itaquasconinae, Meplitumengen. nov., and a new species, Meplitumenalunasp. nov., are described. The new genus has characters present in other genera of Itaquasconinae but in a unique combination. The spiral thickening of the bucco-pharyngeal tube is also present anteriorly to the insertion point of the stylet supports, excluding only the short portion where the apophyses for the insertion of the stylet muscles (AISM) are present. This character is similar to Astatumen Pilato, 1997 but Meplitumengen. nov. differs from this genus as stylet furcae are shaped differently and as stylet supports and placoids are present. The presence of a spiral thickening in a portion of the buccal tube anterior to the stylet supports distinguishes the new genus from Mesocrista Pilato, 1987, Platicrista Pilato, 1987 and Itaquascon de Barros, 1939. Meplitumengen. nov. also differs from Mesocrista, in having the caudal processes of the AISM pointing laterally (instead of postero-laterally), and the apices of the caudal processes of the stylet furcae unswollen. From Itaquascon the new genus also differs by having more robust stylet supports, pharyngeal bulb with placoids, stylet furcae differently shaped. Meplitumengen. nov. also differs from Platicrista in having caudal processes of the AISM more robust and not flexible, and more slender stylet supports. The new species, Meplitumenalunasp. nov., has a cuticle with a very faint roughness at the caudal extremity of the body, and eyes probably absent. The pharyngeal bulb is long, with two long, narrow, rod-shaped macroplacoids; a microplacoid and septulum are absent. The claws are well developed with main branches provided with accessory points, and at the base of the claws, a structure interpretable as a very thin lunule is present. Other cuticular thickenings on the legs are absent.

New taxa of the family Ropalomeridae from Costa Rica are described, and additional records of ropalomerid flies fromMexico and Central America are provided. The new genus and species Acrocephalomyia zumbadoi can be easily distin-guished from all other ropalomerid genera by the following combination of characters: angular forward projection of head,absence of ocelli, flat face, bare arista, long scutum, and scutellum triangular-shaped and dorsally flattened with only onepair of apical bristles with bases approximated. The new species Ropalomera aterrima can be recognized from congenersby remarkable differences of the head, the shape of the scutellum, the absence of scutal vittae, fumose wings, and by theblack coloration of the body, ocellar bristles large, one postpronotal bristle, scutum without pollinose vittae and flat scutellum. Lenkokroeberia chryserea Prado and Kroeberia fuliginosa Lindner are newly confirmed for Costa Rica.

The spine is 40 mm. in length, by 5 mm. in width at the junction _L of the inserted and exserted portions; from this point the spine gradually narrows to a moderately fine point at the apex. The posterior margin is nearly straight, the anterior one gently curved, the curve being more marked distally. The lateral surfaces meet in front at a moderately acute angle, the spine being much laterally compressed. The posterior surface is concave, and each margin is armed with the usual well-marked recurved denticles. The sides of the exserted portion are ornamented with a longitudinal series of ganoine-coated, tuberculated ridges.

This paper has been written in response to a request for determinations of certain parasites of wood-boring beetles in Queensland, Australia. The description of a new species of Monolexis entailed rather more research than was expected and has led to the expression of a few opinions of an exploratory nature on the status of the subfamily Hecabolinae. Altogether one new species in the Doryctinae and six (including one new genus) in the Hecabolinae are described.The types of all new species are in the British Museum.

In this paper we describe a new genus and a new species of Chiridotidae based on specimens collected in shallow water off the South-eastern Brazilian coast. Gymnopipina ikamiaba gen. nov. et sp. nov. is characterized by the complete absence of dermal ossicles in the body, and it differs from the other ossicleless apodids in the number of tentacles and of Polian vesicles, and in the morphology of the calcareous ring. Although not formally tested with a phylogenetic framework, apodids have apparently lost their dermal ossicles multiple times. If these reversions hold true, Gymnopipina gen. nov. represents the fourth independent loss of dermal ossicles in the class Holothuroidea. An identification key to the Brazilian apodid species is also provided.

Part III of the Catalogue of the Fossil Cephalopoda in the British Museum (Nat. Hist.), by A. H. Foord and G. C. Crick, was published in 1897. Since then much fresh material has come into my hands and it is now possible to give much more accurate and fuller details of the horizons and localities at which the various species occur. This is of special importance, in view of the fact that the Goniatites can be used as zone indices of the Carboniferous Series from the upper part of the Dibunophyllum beds (D2 of Dr. Vaughan) up to the Middle Coal-measures. This I showed to be the case in my Presidential address to the Yorkshire Naturalists' Union, and published in the Naturalist, April to July, 1909, and elsewhere. Many details have, however, been added since then, and an elaborated and emended table will be published in a forthcoming paper by myself and Dr. Wilmore, F.G.S., on the Carboniferous succession of some Midland areas.

A new genus and a new species of dendrochirotid, Thandarum hernandezi gen. et sp. nov., is described from Buenos Airescoast in the Southwestern Atlantic. For this species is quite significant the body U shape, up to 14.08 mm (along thetrivium), with double row of podia restricted to the ambulacra. Other features are ossicles from body wall with buttonsand 4 pillar tables, tube feet with rods and end plate star-shaped; the introvert with rosettes and tentacles with rods. Thesecharacteristics require the recognition of a new genus, and the new species and represents the first sclerodactylid reported in Argentinean waters.
