of that part in C. microphthalmia. If distinct, I would pro- 

 pose for it the name of C. depressa. 



MM. Eydoux and Souleyet obtained C. microplithalma at 

 Singapore. 



Chlorideila rotundicauda, sp. n. (PI. II. figs. 5, 6.) 



This species is nearly allied to C. microphthalmia, but differs 

 as follows : — The rostrum is somewhat more elongated ; there 

 is no spine at the antero-lateral angles of the carapace. The 

 carinas of the first to fifth postabdominal segments are very 

 faintly indicated ; those of the sixth segment are strongly 

 defined. The median carina of the terminal segment is 

 thickened and obtuse posteriorly ; the lateral marginal spines 

 are obsolete, and the intervening denticles are small and not 

 acute. The eye-peduncles have the inner margins straight, 

 and are convex only on their outer surface. Length 

 2f inches. 



A single female is in the collection from Formosa (E. 

 Swinhoe, Esq.). It is possible that it may prove to be only 

 an adult state of C. micropihthalma. 



Chlorideila Latreillei. 



Chlorida Latreillei, Evdoux and Souleyet, Voy. Borate, Cr. p. 265, 

 pi. v. figs. 2-5 (1841). 



This species is very nearly allied to C. microphthalmia , but 

 differs in the form of the rostral plate, which is much broader 

 than long and slightly emarginate at its distal end. The 

 antennules are described as large and much longer than the 

 antennas. The inner of the terminal spines of the basal por- 

 tion of the uropoda is represented in the figure as having two 

 acute teeth on its outer margin. 



The raptorial limbs were wanting in the type, which was 

 obtained at Singapore. 



Chlorideila decorata. 



Chlorida decorata, Wood-Mason, Proc. Asiatic Soc. Bengal, p. 231 

 (1875). 



This species has, according to Mr. Wood-Mason, eyes as in 

 C. micropihthalma and C. Latreillei. The inner margin of the 

 sabre-like appendage (basal prolongation) of the uropoda is 

 armed with fine acuminate spines ; and the terminal postabdo- 

 minal segment is vermiculated above and below with granu- 

 lated ridges ; the dactyli of the raptorial limbs are five-toothed. 



This species inhabits the Andamans. I have seen no 

 specimens.
