30 CRUSTACEA MALACOSTRACA. IV. 



ured by Sars; second joint has no crista on the outer side; fourth joint, the merus, is proportionately slender, 

 somewhat elongated and more than twice as long as the ischium; carpus and propodus together about as 

 long as second joint, while in C. pygmcea they are considerably shorter than that joint. Second pair of legs 

 with the 5 distal joints combined longer - - in C. pygmcea shorter -- than second joint; carpus distinctly 

 longer than dactylus, and both very slender and rather elongated. Uropods (fig. 4 g) elongated and slender ; 

 peduncle about as long as sixth, fifth and half of fourth abdominal segment combined, with about n spines 

 on the inner margin ; exopod half as long as the peduncle and somewhat, but not much, shorter than the en- 

 dopod, which has a small apical spine and 12 spines on the inner margin, the most distal of these spines much 

 longer and thicker than the others. 



Length 3.3 mm. 



Remarks. As seen in the description, the male C. tarda differs in a good number of features from 

 the other northern species, C. pygmcea, of which I have seen males taken at Shetland by A. M. Norman. 

 My specimens of C. tarda are all mutilated, so that a couple of less important particulars could not be described. 

 The female can probably be recognized by the number of ocelli and in having antennulse, third maxillipeds, 

 first and second pairs of thoracic legs more slender than in C. pygmcea, finally by the relative length of the 

 joints in these appendages. 



Occurrence. Not taken by the "Ingolf", but by the Ilnd Amdrup-Expedition about at the follow- 

 ing place. 



South-West of the Faeroes; Lat. 6o24' N., Long. n2i' \V., pelagic haul, Sept. 25, 1900, 8 p. m. ; 



10 specimens.

 (PI. II, figs. 5 a 5 d.) 



Adult Male. Carapace rather deep, about half as long again as deep; the dorsal edge considerably 

 convex with about 13 spiniform processes not very regularly distributed and the majority somewhat long, 

 the first longer than the others. Pseudorostrum (figs. 5 a 5 b) moderately short and considerably upturned ; 

 in the single adult specimen the left siphon is a moderately short cone with the end acute, while the right 

 siphon protrudes as a long, membranous tube a good deal more than half as long as the carapace; the ocular 

 lobe has no visual elements and is in the adult specimen as long as pseudorostrum, but it is easily perceived 

 that its terminal part is lost; in a small specimen the ocular lobe is much longer than pseudorostrum, pro- 

 truding as a process with the end acute (and in my figures of the adult this shape is rendered). The anterior 

 margin of the carapace is somewhat concave, the antero-lateral corner rounded with an oblong, strong tooth, 

 and from this tooth to the postero-lateral angle of the carapace runs a row of numerous outstanding teeth, 

 and as this row is curved less downwards than the lower margin, it touches this margin towards both ends, 

 while its median part is somewhat removed from it. The free thoracic segments are together only half as long 

 as the carapace including pseudorostrum ; second to fifth segment each anteriorly with a transverse row of 

 small teeth above and down the sides, but on third and fourth segments the teeth near the dorsal line are 

 rather long, and fourth segment has about four teeth on the dorsal edge. Abdomen slightly longer than the
