560 COLLECTIONS FROM THE AVESTERX INDIAN OCEAN.15. Galathea spinosirostris, Dana ?To this species are rather doubtfully referred female specimenscollected at Marie-Louise Islaud, 17 fms. (No. 186) ; He des Neufs,15 fms. (No. 187) ; aud Providence Island, 19 fms. (No. 187).These specimens differ from Stimpson's description of Galathealahidolepta *, based on specimens from, the Cape of Good Hope, andfrom a dried example (probably male) in the Museum collectionfrom Simon's Bay (J". MacgiUivray, H.M.S, ' Rattlesnake '), only inhaving the strigge of the carapace (in the adult) very scantilypubescent, the lateral margins of the carapace armed with ninespinules, and the palms of the chelipedes very slender and scarcelyscabrous above, but they are spinulose and setose nearly as inStimpson's description.Dana's G. spinosirostris is but briefly described, and he does notstate how many spinules there are on the lateral margins of thecarapace in his types, which were from the Sandwich Islands ; thedescription and figures, however, agree fairly well with our specimens.Dr. Richters refers to this species specimens from the Fouquets.Two small specimens from Darros Island, 22 fms. (No. 233), muchmore nearly resemble G. lahidolepta in the more distinctly strigoseand pubescent carapace, whose lateral margins are armed with sevenor eight spinules (including the infra-antennal spine). In one ofthese specimens (a male) the palm of the chelipede is more broadlydilated and the fingers relatively shorter than in the speciinen fromSimon's Bay referred to above.16. Munida edwardsii. (Plate LI. fig. A.)The carapace, as usual in the genus, is transversely strigose ; thestrigse ciliated ; the lateral spines of the rostrum are rather morethan half as long as the median spine ; outside of the lateral rostralspines there is a small supraocular spine. The front of the gastricregion is armed with a transverse series of about eight spinules ; onthe sides of the carapace, near to the lateral margins, are twospinules, situated one in front of and one behind the cervical suture;the antero-lateral angles of the carapace are bispinulose, and posteriorto these, on the lateral margins, are six spines ; the postabdomen iswithout spinules on the dorsal surface, and the lateral margins ofthe second to sixth segments are rounded. The corneae of the eyesare considerably dilated ; the terminal peduncular joints of theantennules are armed with four spinules, of which one is very long;the peduncular joints of the antenna? (except the last) are eacharmed with a spinule (the flagella, both of antennules and antennse,are wanting in the single specimen examined). The chelipedes (inthe male) are rather robust, the merus enlarging distally and armedwith superficial and marginal spinules at and toward its distal extremity; carpus spinulose above and on the margins ; hand some-* Vido Proc.
