—CETJSTACEA. 31112. Haswellia carnea (Haswell).Calyptura carnea, Hasioell, Proc. Linn. Soc. N. S. Wales, v. p. 476,pi. xvii. fig. 4 (1881) ;Cat. Austr. Crust, p. .302 (1882), nomenffenericiwi 2}>'csuccupatmn.A single specimen of this remarkable genus and species is in thecollection from Port Jackson.The name Gahjptura having been preoccupied in 1843 by Swainson(in tlic Class Aves), I am obliged to adopt a new generic designationfor this species, and would propose to associate Mr. Haswell'sname with a typo which is certainly one of the most interesting ofthe many new forms described by him.The coloration, which is described as crimson by Mr. Haswell,has completely disappeared in the specimen in the Alert ' ' collection*.ANISOPODA.1. Paranthura australis, Hasivell.A single specimen, I think a male, is in the collection fromDundas Straits (17 fms.).I may add the following to Mr. Haswell's brief description :The anterior margin of the front is bisinuated on either side of themedian lobe. The terminal segment is longer than broad, andnarrows to its rounded apex. Of the antennules four, and of theantennae five, joints are visible, besides the rudimentary flagellum.The carpus in all (?) the legs is produced below the inferior marginof the propus or penultimate joint in the form of a blunt lobe or tooth.These characters, which are not indicated in Mr. Haswell's descriptionand figure, render it possible that this specimen may belongtoa distinct species.AMPHIPODA.In the determination of the Amphipoda of the ' Alert ' collectionI have generally followed Mr. Haswell in using Mr. Spence Bate'scl'issification t, rather than that more recently proposed by the lateAxel Boeck J, since the latter author was concerned exclusivelywith north-temperate and Arctic species, and the characters of the* In passing from this notice of the Australian Isopods, I may observe thatthe Idotea caudacuia, Haswell, and /. excavata, Haswell (Cat. pp. 276, 277), areprobably identical, the former with Idotea peronii, Milne-Edwards, and thelatter with /. ungulata, Pallas, as characterized in my recent revision of thegroup (Journ.
