﻿JQ2 CRUSTACEA MALACOSTRACA. II. 



finger of the chelse; from L. profunda it is distinguished by several features, among which may be 

 pointed out the quite different shape of the fixed finger of the chela and the short and not plumose 

 setae of the pleopods. 



Fig. 2 f represents the maxillipeds and fig. 2 e the mandibles of this species. The last-named 

 figure shows that the mandibles are somewhat thick and their molar processes decrease slightly in 

 thickness to the end, which is cut off very obliquely and adorned with about three teeth. The molar 

 processes differ therefore materially from those in the species figured by Sars and remind one more of 

 those in L. ventralis as described on p. 91, though differing in the armature of their end. 



Occurrence. L.laiireniis has been taken by the "Ingolf at three stations. 



East of Iceland: St. 58: Lat. 64° 25' N., Long. 12^09' W., 211 fm., temp. 0.8°; 12 spec, but the 



majority juvenile without pleopods.

 (Pl.X. figs. 3 a— 3 b). 



Female (without marsupium). This species, of which only a single specimen is at hand, is 

 closely allied to L. latireniis, differing only in the shape of the chelae and a little in the uropods. 

 When the chela is seen vertically from the outer side (fig. 3a) it is observed, that the major part of 

 its posterior margin is considerably convex with two setae, the incisive margin a little sinuate and its 

 proximal half slighth- concave with about seven rounded saw-teeth; the movable finger is very much 

 narrower than the proximal third of the fixed finger and has a minute tooth near the middle of its 

 incisive margin; when the fingers have their apical parts crossed a long and moderately broad 

 interval is found between their incisive edges. The uropods (fig. 3 b) have the produced part of the 

 peduncle con.siderably shorter and more rounded than in the two other species of group d. 



Length of the specimen 2.8 """. 



Occurrence. This species has been taken by the II'' Amdrup Expedition at East Greenland 

 at a single locality.

HaploCOpe O. O. Sars. 



This genus, established on a single species, is so closely allied to Leptognathia, that it would per- 

 haps be advisable either to cancel it or to divide Leptognathia into several genera. On p. 9 and 65—66 I 

 have pointed out why I think it premature to subdivide the last-named genus, but as Haplocope has 

 been established may years ago it might probably be nearly impossible to get it cancelled. Haplocope 

 angusta G. O. Sars is a slender species with long uropods and the exopod of these appendages two- 

 jointed; according to Sars it differs from Leptognathia in having the molar process of the mandibles
