500 COLLECTIONS FROM THE WESTERN INDIAN OCEAN. 



15. Galathea spinosirostris, Dana ? 



To this species are rather doubtfully referred female specimens 

 collected at Marie-Louise Island, 17 fms. (No. 18G) ; lie des Neufs, 

 15 fms. (No. 187) ; and Providence Island, 19 fms. (No. 187). 



These specimens differ from Stimpson's description of Galathea 

 labidolepta * , based on specimens from the Cape of Good Hope, and 

 from a dried example (probably male) in the Museum collection 

 from Simon's Bay (J. Macgillivray, II. M.S. ' Rattlesnake '), only in 

 having the strigae of the carapace (in the adult) very scantily 

 pubescent, the lateral margins of the carapace armed with nine 

 spinules, and the palms of the chelipedes very slender and scarcely 

 scabrous above, but they are spinulose and setose nearly as in 

 Stimpson's description. 



Dana's G. spinosirostris is but briefly described, and he does not 

 slate how many spinules there aro on the lateral margins of the 

 carapace in his types, which were from the Sandwich Islands : the 

 description and figures, however, agree fairly well with our specimens. 

 Dr. Eichters refers to this species specimens from the Fouquets. 



Two small specimens from Darros Island, '22 fms. (No. 233), much 

 more nearly resemble G. labidolepta in the more distinctly strigose 

 and pubescent carapace, whose lateral margins are armed with seven 

 or eight spinules (including the infra-antennal spine). In one of 

 these specimens (a male) the palm of the chelipede is more broadly 

 dilated and the fingers relatively shorter than in the specimen from 

 Simon's Bay referred to above. 



10. Munida edwardsii. (Plate LI. fig. A.) 



The carapace, as usual in the genus, is transversely strigose ; the 

 striga? ciliated ; the lateral spines of the rostrum are rather more 

 than half as long as the median spine ; outside of the lateral rostral 

 spines there is a small supraocular spine. The front of the gastric 

 region is armed with a transverse series of about eight spinules ; on 

 the sides of the carapace, near to the lateral margins, are two 

 spinules, situated one in front of and one behind the cervical suture ; 

 the antero-lateral angles of the carapace are bispinulose, and posterior 

 to these, on the lateral margins, are six spines ; the postabdomen is 

 without spinules on the dorsal surface, and the lateral margins of 

 the second to sixth segments are rounded. The corneae of the eyes 

 are considerably dilated ; the terminal peduncular joints of the 

 antennules are armed with four spinules, of which one is very long ; 

 the peduncular joints of the antenna? (except the last) are each 

 armed with a spinule (the flagclla, both of antennules and antennae, 

 are wanting in the single specimen examined). The chelipedes (in 

 the male) are rather robust, the merus enlarging distally and armed 

 with superficial and marginal spinules at and toward its distal ex- 

 tremity ; carpus spinulose above and on the margins ; hand some-
