of course. The two small spinules which on the cardiac region overhang anteriorly the cervical 

 groove, are a little larger than in the quoted figures of the "Illustrations". The cardiac 

 region, that appears one and a half as broad as long, is defined laterally from the branchial 

 regions by rather prominent ridges. There is no carina distinguishable in the mid-dorsal line 

 of the i^' abdominal tergum and also barely one on the 2"'^, but on the four following they 

 appear gradually more distinct. The telson, which is i i mm. long and 6^3 mm. broad, is 

 comparatively longer than that oi Ah'p/iropsis Stc^vai-fi W.-Mas., which, in the female, 

 described p. 112, is 'J^|^ mm. long and 5^- mm. broad. The exopodite of the caudal swimmerets 

 bears a small spinule on its outer border at the outer e.vtremity of the very fine, transverse 

 suture. The abdominal appendages (of the female) are similar to those of Nephropsis Stewarti. 



The eye-peduncles also fully agree with this species and are covered by the rostrum. 



Internal antennae little longer than the carapace, the rostrum excluded; the 3'''^ joint of 

 the peduncle, which is 10 mm. long, just as long as the carapace is broad anteriorly, is about 

 equal in length to the i*' and 2"'^ taken together. The flagella, of which the outer is distinctly 

 thicker than the other, are one and a half as long as the peduncle. External antennae 150 mm. 

 long, about twice as long as the body and about /-times as long as the carapace, without the 

 rostrum, and somewhat more than 3-times as long as the abdomen; the peduncle reaches the 

 middle of the 3"' joint of that of the inner antennae, as far forward as the external maxillipeds. 



The right cheliped, a little larger than the left, is 42 mm. long, nearly as long as the 

 abdomen. There is a longitudinal row of 4 short spines on the lower border of the merus 

 and a 5"' near the distal end of the inner, one spine just behind the distal end of the upper 

 border and another at the end of the outer. These legs appear much slenderer than those 

 of the female of NcpJiropsis Stewarti. The carpus of the right leg, indeed, is 8 mm. long and 

 just half as broad, while that of the female of Nephropsis Stewarti is one and a half 

 as long as broad. This joint carries above 4 spines, arranged exactly as in Figure 2 of the 

 "Illustrations" and a 5"^ at the end of the lower side. The hand is 16 mm. long, twice as 

 long as the carpus; the dactylus is a little longer than the inner border of the palm and the 

 palm is 4Y.- mm. broad near the articulation of the fingers, so that the chela appears almost 

 4-times as long as broad, while the chelae of the female of Nephropsis Steivarti are 

 2Vo-times as long as broad. The little shorter left les: agrees with the ris^ht and both are 

 covered with a shaggy tomentum. 



The following legs look like in the "Illustrations", the propodite of the 5"^ pair terminates, 

 like in Nephropsis Stcivarti^ in a sharp tooth at the end of its lower border.
