77. Actasa flosculata, n. sp. 



Nearest to Actasa acantha, A. M. E., and A. hystrix, Miers. 



Characterized by the close investment (carapace, chelipeds and 

 legs) of peculiarly ornamental fungiform tubercles which become petaloid 

 at the margins. 



Carapace f as long as broad, convex ; all the regions well defined 

 by conspicuous grooves, and convex ; the regions again subdivided into 

 few convex lobules by less conspicuous grooves. The whole carapace, 

 except the broader grooves between the regions, closely covered with 

 very elegant tubercles which have constricted stalk-like bases and thin 

 broad oval or kidney-shaped tops. The exposed surfaces of the cheli- 

 peds and legs are covered with ornaments similar to those on the 

 carapace, except at the edges, where they become petaloid. 



Front broadly bilobed, the edge of each lobe being deeply cut into 

 four projecting petals. Supra-orbital margin deeply scallopped : antero- 

 lateral borders ornamented like the surface, obscurely lobed : postero- 

 lateral borders about equal in length to the antero-lateral, straight. 



The terminal abdominal terga and the sternum of the male pitted 

 and worm-eaten, but with a glazed appearance : under surface of cara- 

 pace, as far as the epimeral suture, covered with pearly granules. 



The basal antennal joint stops far short of the inner angle of the 

 floor of the orbit. 



Fingers short, blunt pointed, slightly hollow at tip. 



Colours in spirit light yellow, fingers brown with white tips. 



In the Indian Museum are two specimens from oh Ceylon, 34 fms. 

 and one from off Maldive Is. 28 fms. The carapace of the larger one 

 is 8 millim. long and 12 millim broad. 



The ornamentation of this species gives it a strong resemblance to 

 Chlorodius fragifer White, with which it may probably prove to be 

 identical.
