CEtrSTACEA. 311 



12. Haswellia carnea (Haswell). 



Calyptura carnea, Haswall, Proc. Linn. Soc. N. S. Wales, v. p. 476, 

 pi. xvii. %. 4 (1881) ; Oat. Austr. Crust, p. 302 (1882), nomen 

 genericum presoccupatum. 



A single specimen of this remarkable genus and species is in the 

 coUeotion from Port Jackson. 



.The name Galyptura having been preoccupied in 1843 by Swain- 

 son (in the Class Aves), I am obliged to adopt a new generic desig- 

 nation for this species, and would propose to associate Mr. Haswell's 

 name with a type which is certainly one of the most interesting of 

 the many new forms described by him. 



The co].oration, which is described as crimson by Mr. Haswell, 

 has completely disappeared in the specimen in the ' Alert ' collec- 

 tion *. 



ANISOPODA. 

 1. Faranthura australis, Haswell. 



A single specimen, I think a male, is in the collection from 

 Dundas 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 the 

 median lobe. The terminal segment is longer than broad, and 

 narrows to its rounded ape:X. Of the antennules four, and of the 

 antennse five, joints are visible, besides the rudimentary flagellum. 

 The carpus in all (?) the legs is produced below the inferior margin 

 of the propus or penultimate joint in the form of a blunt lobe or tooth. 

 These characters, which are not indicated in Mr. Haswell's descrip- 

 tion and figure, render it possible that this specimen may belong 

 to a distinct species. 



AMPHIPODA. 



In the determination of the Amphipoda of the ' Alert ' collection 

 I have generally followed Mr. Haswell in using Mr, Spence Bate's 

 classification t, rather than that more recently proposed by the late 

 Axel Boeck J, since the latter author was concerned exclusively 

 with north-temperate and Arctic species; and the characters of the 



* In passing from this notice of the' Australian Isopods, I may observe that 

 the Idotea caudacuta, Haswell, and /. excavata, Haswell (Cat. pp. 276, 277), are 

 probably identical, the former with Idotea peronii, Milne-Edwards, and the 

 latter with /. ungulata, Pallas, as characterized in my recent revision of the 

 group (Journ. Linn. Soc, Zool. xvi. p. 1, 1881).
