fourth about twice as long as wide, about as long as second 

 and third; fifth about one-fourth longer than fourth; flagellum 

 multiculate, thirty-four articles. First antenna? extend to end 

 of peduncle of second antenna? ; the latter extend to end of fifth 

 thoracic segment. Maxilliped composed of seven articles; the 

 last four very plumose; third is provided with two hoops or 

 blunt spines. Mandible carries a palp of three articles and a 

 toothed molar. Frontal If^mina, distinct, short and broad, 

 anterior margin triangulate though not sharply so. 



First segment of thorax large, twice as long as third and 

 fourth segments. Succeeding segments almost equal in length, 

 though second is very slightly longer than third and fourth. 

 Epimera are very distinct on all but first segment. Last four 

 are produced at post-lateral angles especially the sixth and 

 seventh. A carina is apparent on all the epimera, longitudinal 

 in the first two and olilique in the last four. First three legs 

 prehensile, remaining ambulatory. On propodus of first there 

 are three prominent spines ; one on the carpus ; on the merus 

 seven prominent blunt spines and about three sharp ones; 

 ischium has one blunt s]iine like those of the merus, also a large 

 spine on the outer distal margin. Second leg has three or four 

 sjiines on the propodus; three on the carpus; eleven blunt 

 spines on the merus and two spines on outer distal margin; 

 ischium has two blunt spines, one large and two small ones on 

 outer distal margin. Ambulatory legs provided with many 

 robust spines. 



Abdomen in the specimen described shows only three seg- 

 ments, four or five may be visible, however, but first is usually 

 concealed. Sixth broad at proximal end, attenuated poster- 

 iorly; apex rounded, provided with many strong spines, twelve 

 to twenty-two. Inner branch of uropoda as long as terminal 

 abdominal segment ; broad at distal end where it is armed with 

 spines. Outer branch is shorter than inner and narrower; also 

 armed with spines on distal end and outer margin. Peduncle 

 of uropoda produced to two-thirds length of inner ramus. First 

 and second pleopoda of male provided with many compound 

 hairs; second has a long stylet.
