;192 COLLECTIONS FEOM MELANESIA.specimens in the British-Museum collection scarcely any tracesexist of the meral spines above mentioned. I may add that Ihave observed a considerable degree of variation in the length ofthe rostrum in the large series of specimens of this species in thecollection of the British Museum. In the type specimen of Egeriaindica of Leach in this collection the third joint of the outer maxillipededoes not in reality present any peculiarity of form, nor doesthis specimen differ from ordinary adult examples of the genus.I believe, then, it will be necessary to unite under one specificdesignation the three forms Er/eria arachnoides, E. herbstii, andE. indica, mentioned by Milne-Edwards*, and that to this speciesthe name arachnoides must be applied rather than the Linneandesignation longipes, because Linnteus's description of his Cancerlongipes f differs in several particulars from Egeria arachnoides ;thus he says " manus ovatce, muricatce," or " scabrce," whereas inEgeria arachnoides the hands are always elongated and smoothmoreover, in the middle line of the carapace are five (not four)tubercles or short spines ; other distinctions might be mentioned.Specimens of Egeria arachnoides are in the Museum collectionfrom the Indian Ocean (Hardiuicke), Philippine Islands, Zebu(Cuming), Shanghai {inirchased of Jamrach), Port Curtis, Australia(J. Macgillivray), &c. ; several other jN^.E. Australian localities arerecoi'ded by Mr. Haswell.The species designated Egeria longipes, M.-Edw., by Adams andWhiteJ, if correctly characterized, differs from any specimen of thegenus I have seen in its very much broader, transverse front, andmay belong to a distinct species.8. Chorilibinia gracilipes.Miers, Ann. Sf Mag. Nat. Hist. ser. 5, xix. p. 7, pi. iv. fig. 4 (1879);Hastvell, Proc. Linn. Soc. N. S. Wales, iv. p. 439 (1880) ; Cat.Austr. Crust, p. 17 (1882).In Dr. Coppinger's first collection two adult females were receivedfrom Port MoUe, 14 fms. (No. 93), and one from Albany Island,3-4 fms. (No. 109). In the second collection are a male and femalefrom Port Darwin, 7-12 fms. (No. 173).The types in the British Museum are from Papua, and Mr. Haswellrecords the occurrence of this species at Cape Grenville.9. Paramithrax (CMorinoides) coppingeri, Hasivell.An adult female is in the collection from Port Darwin, 12 fms.,and two small males from Dundas Strait, 17 fms. (No. 161).
