CRUSTACEA MALACOSTRACA. 11. ry 



Occurrence. Taken by the "Ingolf at a single station. 



South of the Davis Strait: St. 38: Lat. 59° 12' N., Long. 5i°05' W., 1870 fm., temp. 1.3°; i spec. 



35 Typhlotanais inaequipes n. sp. 

 (PI. V, fig.s. 9a— 9b; PI. VI, figs. la— ic.) 



Female (without marsupium). Body slender, a little more than .seven times as long as broad, 

 seen from above nearly cyHndrical (fig. la). ~ Carapace as long as or a little shorter than the two 

 following segments combined, not fully lialf as long again as broad; its lateral margins are nearly 

 parallel from the base to near the beginning of their distal third, where they begin to converge more 

 distinctly; the anterior end is scarcely more than half as broad as the base and the rostral process is 

 middle-sized, acute. 



Antennulse considerably shorter than the carapace (fig. i c), somewhat slender. First joint, seen 

 from the side, about or not fully three times as long as deep and tapering somewhat irregularly from 

 somewhat from the base to the end ; seen from above the joint (fig. i b) is nearly three times as long 

 as broad and tapers nearly regularly; the joint is .somewhat or considerably longer than the two other 

 joints combined. Second joint from a little less to a little more than half as long as the third and 

 at most about twice as long as deep; longest terminal setae distinctly longer than third joint. — An- 

 tennse of normal length (fig. ic); third joint somewhat thickened; fourth joint at most half as long 

 again as the penultimate; terminal setre about as long as those of the antennulse. 



Chelipeds (fig. ic) somewhat long but only moderately robust. The basal joint somewhat long, 

 its posterior process large, a little longer than deep with its rounded hind margin considerably distant 

 from the front margin of second thoracic segment; carpus considerably longer than the basal joint, 

 three and a half times as long as deep. Chela a little shorter than the carpus, a little less than four 

 times as long as broad; movable finger a little shorter than the front margin of the hand; fixed finger 

 at the base somewhat thicker than the movable. 



Thoracic segments with the lateral margins parallel excepting on second and seventh seg- 

 ments, on which the margins converge feebly respectively from the front angles backwards and from 

 behind forwards. vSecond segment about two-thirds as long as the third, without ventral process; fifth 

 segment a little longer than the fourth or the sixth and scarceh as long as broad. — Thoracic legs 

 moderately strong. Second pair (fig. ic) quite peculiar; fourth joint \'ery elongate, alxnit two and a 

 half times as long as the fifth; sixtli joint slightl\' more tlian half as long again as the fifth; seventh 

 joint with claw as long as the fifth; setse short. Third pair normal; fourth and fifth joints subequal 

 in length; sixth joint about half as long again as the fifth and more than twice as long as the 

 seventh with claw; the setse moderately short excepting a somewhat long, distal seta from the side 

 of sixth joint. Tln-ee posterior pairs not very characteristic; second joint (fig. 9a) about two and a 

 half times as long as broad; fourth joint with a minute distal tooth; fifth joint slightly broader than 

 the fourth, with one of the margins somewhat convex but witliout an\- distinct armature; sixth joint 

 raoderateh- or rather slender, almost as long as the two preceding joints combined, with a minute 

 spine .somewhat before the end; .seventh joint with claw of middle length. 



Abdomen slightly broader than the posterior thoracic segments and scarcely as long as the
