﻿CRUSTACEA .MALACOSTRACA. II. .j 



Chelipeds (fig;. 6c) nioderateh' iol)n.st. ISasal joint witli tlie ijo.stcrior protuberance somewhat 

 .short, posteriorly rounded; its hind inar<;in ratlier distant from tlie lower front ano-lc of second thoracic 

 segment. Carpus a little longer than the basal joint and a little more than twice as long as deep, 

 with liotli margins feebh' convex. Chela (fig. 6d) as long as the carpus, a little nu)re than three times 

 as long as broad; movable finger somewhat longer than the anterior margin of the hand; fixed finger 

 much broader than the nio\-able, with aliout three teeth along the distal part of the incisi\-e margin 

 and the last tooth rectangular and much larger than the two other teeth. 



Thoracic segments (fig. 6a) differ slightly in breadth; all are snbrcctangular with the angles 

 a little rounded; the major part of their lateral margins parallel or feebly convex. Second segment 

 conspicuoush' less than half as long as the third, without an\- process below. The segments increase 

 in length from the second to the fifth and decrease from the fifth to the seventh, but the fourth seg- 

 ment is slightb' longer than the third and slightly shorter than the fifth. — The anterior legs moder- 

 ately long and slender. Second pair (fig. 6c) with a very long seta both from the anterior and the 

 posterior distal angle of fifth joint; sixth joint about as long as fifth joint plus half of the ftnirth, 

 with the distal sette short; seventh joint with claw slightly longer than sixth joint. Third pair some- 

 what shorter than second; fourth joint with a long seta from the distal posterior angle, fifth joint with 

 a \'erv long seta both from the anterior and the posterior distal angle; sixth joint somewhat longer 

 than fifth, with short seta;; seventh joint with claw distincth' more than half as long as sixth joint. 

 Sixth and seventh pairs (fig. 6e) with the second joint somewhat widened, two and a half times as long- 

 as broad; fourth joint feebh' tapering and with a short spine at the distal anterior angle (fig. 6f|; 

 fifth joint moderately broad, slighth' broader towards the end and with a small, low, glabrous jjro- 

 tuberance just before the end of the anterior margin and a minute sj)ine at the end; sixth joint only 

 a little longer than the fifth, \er\- nioderateh' slender, with a spine near the distal anterior angle; 

 seventh joint with claw about half as long as sixth joint. 



Abdomen somewhat longer than and as broad as the two preceding segments combined. — 

 Uropods somewhat short; endopod (fig. 6g) two-jointed, with first joint slighth' longer than the 

 second; exopod slightly or a little longer than the proximal joint of the endopod. 



Length of females without marsnpium 2.3'"'"; females with marsn])ium unknown. 



Immature Male. Differs from the female in the antennuke, which are thickened as in the 

 }'oung male of /'. iiiticroiialiis. 



Remarks. This species is allied to T. pciiicillatitx. but it is somewhat larger, a little more 

 slender and differs in the shape of the carapace, in ha\ing se\-enth joint with claw of second and third 

 jiairs of legs much longer in proportion to the sixth joint, in possessing long or ver\' long seta; on 

 fifth joint of these legs, in haxing the exopod of the nroj^ods considerably shorter and uujointed, 

 and no \'eutral jirocess on second thoracic segment. T. priiicillatus is a warm water species, while 

 T. nicniiis is known only from the cold area, with the temperature below zero. 



Occurrence. This species has been taken by the "Ingolf" at four stations.
