Report on the zoological collections made in the Indo-Pacific Ocean ...

CRUSTACEA. 203type of their description is in the collection of the British Museum,and is of very small size (length G lines, 12| millim.) ; surface of thecarapace nearly smooth, with the regions little prominent and butslightly granulated ; a spine on the gastric and cardiac regions anda somewhat obscure ridge on the branchial regions ; teeth of theantei'o-lateral margins nearly confluent, postero-lateral spines withscarcely any traces of lateral teeth &c. Very similar characters areexhibited by the small specimen from Port Molle (No. 03). In thesmaller male from Thursday Island (No. 177) and in two specimensfrom the Australian seas, the largest of which measures about10 lines (21 millim.), and which were dredged by Mr. Macgillivraydi;ring the voyage of H.M.S. Eattlesnake,' in 7 fms. between Percy'Island and the mainland, in lat. 21° 50' S., long. 150° 20' E., thereis a considerable approach to the larger specimens from ThursdayIsland : in all the spines of the gastric and branchial regions arenearly obsolete ;but in two specimens the carapace is nearly smooth,in the others it is granulated nearly as in the large specimen fromDr. Coppinger's collection, the spines of the postero-lateral anglesare less prominent and less distinctly laciniated than in that example,though bearing distinct traces of lateral teeth.I have entered thus fully into the distinctions observable betweenthese specimens, because of the great degree of variability that existsin many species of Parthenopidae ; no one, I think, comparing twospecimens at opposite ends of the series would regard them as belongingto one and the same species.29. Cryptopodia fornicata {Fahr.).Port Curtis, 11 fms. (No. 87), a female, first collection ; ThursdayIsland (No. 175), second collection, a young male. Specimensare in the British-Museum collection of this common species from theIndian Ocean {GeneralUardwicl-c) ; Borneo (from the India-Museumccllecilon) ; Philii)pine Islands, Mindoro {Cumhvj); Japan (Jamracli); Lizard Island {J. Macr/iJlivray); and Moreton Bay ( Warivick).Additional Australian localities mentioned by Mr. Haswell are BrookIsland, Cape Grenville, and Port Denisou.It was collected in the Chinese seas during the voyage of H.M.S.' Samarang.'A very small male from Thursday Island (No. 165) has the carapaceand under surface of the chelipedes smooth, the gastric depressionshallow, and scarcely any trace of the oblique ridges onthe branchial regions usually characteristic of C fornicata.30. Cryptopodia spatulifrons, Miers.An adult male was received with Dr. Coppinger's second collectionfrom Thursday Island, 3-4 fms. (No. 175), and a smaller malefrom Prince of Wales Channel, 7 fms. (No. 169).The larger examj^le has the carapace more distinctly and coarselypitted than the typical specimen in the Museum collection from
