736 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxv. 



Length from 6 to 7 mm. ; no other dimen.sion.s given. Color, green 

 marbled with blue. 



Habitat. — Guiana, from a species of Anguilla. 



{striata = striped, in allusion to the lines on the ventral surface 

 caused by the arrangement of the spines.)

Carapace elliptical, rather large, but not covering- the swimming- 

 legs. Abdomen broadl}' elliptical instead of triangular, with a deep 

 anal iissure, which is slit-like in shape; lobes well rounded; anal 

 pa])illa? small and basal. 



Anterior maxillipeds have no protuberance opposite the terminal 

 claw; the second maxillipeds have only two teeth on the posterior 

 margin of the basal plate instead of three; the teeth between the bases 

 of tiiese maxillipeds are long and slender, but rather blunt. Both 

 pairs of antennie are slender and the anterior ones have no spine on 

 their basal joints. 



The spines on the ventral surface of the carapace are slender and 

 about of a size in the region between the antennae, but those extend- 

 ing- backward in a row along the margin of the carapace are much 

 smaller. In the male the testes are two-lobed and the accessory capu- 

 latory apparatus is quite complicated. The latter consists of two 

 unequal lobes on the posterior border of the second basipod joint of 

 the second legs, and a pair of very long and convoluted papillae on 

 the basal joints of the third and fourth legs. Those on the third legs 

 are on the posterior border, those on the fourth legs on the anterior 

 border. This species is very small compared with the preceding ones, 

 being- only 2 to -i mm. in length. Color, a violet brown, due to pig- 

 ment granules, which are arranged in sinuous lines or in a cobweb 

 pattern. 



Ilahitat. — Guiana on a species of AnguiUa. 



{Jyldentata — two-toothed, because it has only two teeth on the basal 

 plate of the second maxillipeds.)
