Indian River, Barbados, May 21; three specimens. 
Without the legs of the second pair which are wanting in 
each of these specimens, it is not possible to determine them 
satisfactorily. A rostral count gives 14 for two of the spec- 
imens and 15 for the third. One of the former is the largest 
of the three and measures about 27 mm. long; the rostrum is 
longer than the antennular peduncle and just about as long as 
the antennal scale, four of the dorsal teeth are on the carapace; 
the rostra are rather straight, the apices of the dorsal teeth 
being in about the same line which is inclined a little down- 
wards from the third tooth to the tip; the first tooth is a little 
lower than the second, and the tip of the second is just below 
the level of the apex of the third which is the highest of the 
series. The shorter ramus of the bifureate antennular flagellum 
is composed of 5-6 fused and 15-16 free articles; in one of the
