the branchiostegal and only about one and a lialf times as 

 large as the anterior rostral spines. Tlie rostrum, whicli 

 extends beyond the autennulary peduncle by about the length 

 of the lateral spine of the carapace, is somewhat recurved 

 and is marked on tiie dorsal surface by two rows of elongate 

 foveas, whicli are much more distinct in the female than in 

 the male; its spines are small, especially the posterior, which 

 are rather sliort and stout. The broadly oval antcnnal scale 

 all but reaches the level of the end of the antennulary 

 peduncle ; the spine of its outer margin is rather well deve- 

 loped and is placed about one third ot the way from the base 

 to the apex. 



The eyes are in both sexes somewhat reduced, in our only 

 female very unequally so — the right being scarcely half the 

 size of tlie left, while in our two males they would appear to 

 be quite equal on both sides. From the opaqueness of the 

 cornese and other marks of degeneration it may with confidence 

 be inferred that this S|>ecies is quite blind. 



The olfactory flagellum of the antennules is much thicker 

 in the male than in the female. The dactylopoditcs of the 

 last two pairs of legs are of the oidinary form — lanceolate, 

 with the dorsal surface concave and the ventral subcarinate. 



Abdomen much as in the preceding and probably other 



members of the same section ; the dorsal ridge of its last 



tergum is in the female entire, in both males obsoletely 



notched ; the dorsal ridge of the telson seems urmsually long.
