Plate XXXVIII. Figures 21-22. 



Body narrow, elongate. Color dark brown, with scattered black 

 dots. 



Head with lateral angulations prominent, rounded, between which 

 the front is excavate on either side of a small median point. Eyes 

 large, situated in the lateral angulations. 



First pair of antenna have the first joint of the peduncle oblong, 

 the other two shorter and about equal in length, flagellum six to 

 seven jointed. The second pair of antenna? have a five-jointed 

 peduncle, (the first joint being short and indistinct,) of which the 

 second and fifth joints are longest, the flagellum being consolidated 

 into a single, flattened, tapering joint, furnished with hairs. 



The first five thoracic segments are of equal length. The sixth is 

 somewhat shorter than any of the others, and the seventh is half as 

 long as the sixth. 



The abdominal segments are distinct, the first five taken together 

 being no longer than the seventh thoracic segment. The terminal 

 abdominal segment is long and narrow, rectangular in shape, with 

 margins entii-e. The basal joint of the uropoda is half as long as 

 the terminal segment of the abdomen ; the inner branch is rectangu- 

 lar, coarsely denticulate, and reaches the apex of the telson. The 

 outer superior branch is narrow, elongate, rectangular, with mar- 

 gins coarsely denticulate, the teeth being close together. 



The branches of the uropoda and the terminal abdominal segment 

 are fringed with long hairs. 



The first three pairs of legs ai*e sub-chelate. The second and third 

 pairs have the posterior margin of the propodus armed with spines, 

 as in the preceding species. In the following four pairs of legs the 

 anterior margin of the propodus is armed with four spines. 



A single female was collected by A. E. Verrill and party in 1898,
