STDDIBS IN ADSTRALIAN CRUSTACEA McCULLOCH. 235 



Nomenclatiire. — In identifying tliese specimens as T. leich- 

 ardti, I am guided rather by a consideration of the locality 

 whence that species was obtained than by the meagre 

 characters referred to by Miers. He had two examples from 

 different sources, the localities of which he gave merely 

 as East Australia, but according to the notes of the late 

 Mr. F. E. Grant, he examined a specimen in the British 

 Museum which was labelled ^'■Telphiisa lelcharcUi, sp. nov., ^. 

 Australia, Lat. 27" 9', Long. 144°." This position is in South- 

 western Queensland, and is well within the area over which 

 the species described above ranges. As already stated, how- 

 ever, I think it probable that '/'. leichardti is not distinct from 

 T. transversa, the types of which were obtained at Cape York. 



Variation. — The Australian Museum collection includes 

 nineteen examples from different localities which appear to be 

 specifically identical, though they exhibit considerable variation 

 in several structural details. The fronto-orhital nudth ranges 

 from 1.9-1.7 in the width of the cephalothorax ; that this is 

 merely individual variation is pi'oved by the fact that it differs 

 in individuals which have been collected together, while a 

 series of specimens shows an unbroken range of intermediate 

 stages. The coavexitij of the haclc is evidently a very variable 

 character. Notwithstanding the very different appearance of 

 markedly convex examples from New South Wales, and others 

 much flatter from King Sound, North West Australia, an in- 

 termediate series seems to preclude the possibility of the two 

 being distinct species or even subspecies. On the oilier hand, 

 four from North-eastern Queensland, in which the carapace is 

 particularly flat, may be conveniently separated as a distinct 

 variety under the name pJa)ia. The width of the abdomen in 

 both sexes is variable; the form of the male abdomen is shown 

 in my figure, but the proportions of the component segments, 

 and particularly of the last three, are somewhat variable; the 

 female abdomen may entii'cly cover the sternum, or leave a 

 portion exposed on either side. The riKjosity of the legs varies 

 somewhat in different specimens, as do the fine lines on the 

 sides of the carapace, but to a less degree than the other 

 features noted. 



Locs. — The two specimens described in detail were collected 

 by Mr. F. L. Berney twenty miles west of Hughenden^ North 

 Queensland, where the species is quite common, occuri'ing in
