first of which is much the longest. The flagellum of the second 

 antennae consists of fourteen articulations, the third is rather 

 shorter than those preceding or following, the sixth, seventh, and 

 eighth are equal in length to that of the first.

Anteriorly, the body of the adult male is somewhat narrowed, 

 the frontal margin being a little more than half the posterior 

 width of the first peraeon segment; from this point the body 

 gradually increases in width to the sixth segment. The cephalon 

 is about one-third longer than the first segment of the peraeon, 

 the latter is equal to any two of those succeeding. The whole 

 upper surface of the body, including the uropods, is minutely 

 granulose ; the second and following segments have a transverse 

 series of subconical tubercles seated on the anterior margin ; the 

 third to sixth with similar but smaller series, which are some- 

 what unequal in size and in distance apart, and nearer to the 

 hinder margin than to the middle. The pleon exhibits two or 

 three lateral sutures indicating the coalesced segments, each of 

 which is marked by a more or less distinct row of granules. 



The terminal segment has a slight longitudinal median 

 depression, which is also indicated on the preceding segment, 

 laterally, the sides are convex, and ornamented with two clusters 

 of small tubercles, those situated distally are seated on a slight 

 oVjlique ridge, posterior margin with three blunt processes, the 

 median one is somewhat elevated superiorly and shorter than 

 lateral pair. First antennae with the basal joint stout, about 

 three times as long as broad, without the marginal denticles ; 

 the latter are four or five in number, they project along the 

 anterior border and gradiiall}'^ increase in size outwardly. 

 Second joint about equal in length and breadth to half the width 

 of the first ; third joint slender, five times as long as 1)road.
