 VIATA, DORSAL VIEW OF 

 FEMALE. X 23. 



The segments of the thorax are distinctly defined. The e]:)iniera are 

 distinct on the first three segments, where they occupy the anterior 

 portion of the hiteral marg-in; they are ([uite dis- 

 tinct on the longer side of the body, but it is 

 impossible to distinguish them on the shorter side. 

 Ovarian bosses are not present on any of the seg- 

 ments. The epimera of the last four segments 

 are not separated off from the segments; they 

 occupy the entire lateral margin. 



The abdominal segments are complete!}^ fused 

 in the middle of the abdomen. On the lateral 

 margin of the shorter side of the body there is 

 no indication whatever of the coalesced seg- 

 ments. The first four abdominal segments are 

 represented on the longer side of 

 the bod}^ by four rounded lobes. 

 The last two segments are completely 

 fused, and are not indicated on either side. 



The pleopoda, as far as could be made out, consist of 

 four pairs of single branched lamellje. Three pairs were 

 distinctly seen; the last pair are very indis- 

 tinct. 



The first lamella of the marsupium on the 

 shorter side extends about one-third the length of the body; 

 on the longer side, the first lamella extends to the posterior 

 margin of the second thoracic segment. 



Male with head large, rounded in front. 

 Eyes large, irregularly shaped. All seven 

 segments of thorax distinct. A])domen nar- 

 rower than thorax, and tapering to a narrow extremity. 

 In one specimen all six segments were more or less de- 

 fined at the sides; in the other specimen only the first 

 three. Length of abdomen about equal to one-third the 

 length of the body. 



Color white with markings of black or brown. 

 Nine specimens were collected by Mr. Henry Hemphill 

 at Puntarasa, Florida, on Hippolyte zostericola (Smith). 



This species differs from Bopyrina vlrl))l (Waltz)," in 

 the much smaller first lamellae in the female, the lamella 

 of the shorter side of the marsupium extending but one- 

 third the length of the body, while in B. virhil it extends 

 nearly to the abdomen, that of the longer side reaching only the pos- 

 terior margin of the second thoracic segment, while in B. v!rl)u. it
