segment. The proximal segment has about ten subequal spines and a stronger distal 

 one on its inner edge, and a minute distal spinule externally. The distal segment has 

 one long and two short terminal spines and a small spinule on the inner edge. 



The pigmentation is variable ; patches are generally present on the back and sides 

 of the carapace, and some specimens have dendritic spots on the sides of the abdominal 

 somites. 



Beviarks. — This species is very closely allied to V. cristata, but it appears to differ 

 in a number of small characters, of which the convex dorsal edge of the carapace and 

 the shorter first legs are the most conspicuous.

The specimen which I refer to this species is a female wdth developing but empty 

 brood-pouch. It measures 22-5 mm. in length of body, and is thus more than half as 

 long again as Sars's immature specimen. It differs from the latter in the following 

 particulars : — 



The carapace is less deep, its vertical depth being less than two-thirds of its length, 

 its lower edge is less convex, and the antero-lateral margin as seen from the side is 

 proportionately deeper. The ocular lobe reaches quite to the tip of the pseudorostrum, 

 and the dorsal edge of each lateral plate, where it lies against the ocular lobe, is 

 convex instead of concave. The antennal notch is much shallower than in Sars's figure. 

 The pleural plates of the third free thoracic somite are produced backwards on each 

 side as large rounded lobes, and those of the fourth somite are similarly but less 

 strongly produced, while the last thoracic and the first four abdominal somites have 

 the lower hinder corner slightly produced. The appendages, so far as they are 

 preserved and can be seen without dissection, agree in general with those of Sars's 

 specimen. The second leg, however, appears to be longer, reaching as far as the 

 anterior margin of the carapace in the natural position. The posterior legs are 

 somewhat shorter and more robust. The uropods differ from the figure given by Sars 

 in having setae on the outer edge of both segments of the endopod, and in having the 

 distal segment little shorter than the proximal, while in Sars's figure it is about two- 

 thirds of that length. 



In view of the much smaller size and the immaturity of the type-specimen, the 

 characters in which it differs from the present specimen cannot be regarded as of 

 specific value.
