AUSTRALIAN LAXD SHELLS. 25 



being broader, sub-depressed, almost smooth, and the umbilicus of 

 the same colour as the rest of the shell, instead of being chestnut, 

 surrounded by a yellow band. A variety, of which I have numerous 

 specimens from the Richmond River, differs in being duller above, 

 in the greater completeness of the ribs which are scarcely fainter 

 towards the mouth, and in the entire absence of the spiral lines 

 occasionally met with in this fine species. 



64. Helix Leichhardti. Cox. Plate V. Fig. 1. Australian 

 Museum. 



Cox, Catalogue of Australian Land Shells, p. 3-3, 18G4. 



Shell umbilicated, conoiclly-sami- globular, rather thin, glossy, closely, 

 not very regularly, and frequently anastomosedly striated, with no 

 indications of spiral decussating lines, reddish-yellow, tinged with 

 green, with some dark irregular radiating streaks ; spire convex, 

 obtuse ; whorls 4^, moderately convex, last very large, inflated, 

 deflected at the mouth, depressly-convex above, flattened at the 

 mouth ; below convex, a faint yellow ring round the umbilicus, 

 which is perspective, and equals ^ of diameter ; aperture oblique, 

 irregularly ovately-lunate, broader than high ; peristome simple, 

 plain, straight, right margin nearly straight, anterior and columellar 

 margins gradually merging, arcuately curved, very slightly dilated 

 and reflected above. 



Diameter, f/reatest 1-40; least P20; height 050 of an inch. 



Habitat. Australia. Leichhardt. 



65. Helix capillacea. Fer. Plate VI. Fig. 7 ; and Plate XL 

 Fig. 8. M.C. 

 Fer., Hist., p. 206. PI. LXXXII. F. 5. 



Shell umbilicated, depressed, closely and almost regularly striated, 

 thin, glossy, horny-yellow; spire scarcely or not at all showing; 

 whorls 4, quickly increasing, flatly-convex, last very large, de- 

 pressly-convex, not descending in front ; base more convex, 

 smoother, more glossy; umbilicus pervious, about 1 -5th of diameter; 

 aperture diagonal, transversely, lunately-oval, wider than high; 

 peristome simple, thin, straight, margins approximating, columellar 

 margin very slightly expanded. 



Diameter, greatest - 95 ; least 0'80 ; height 0-27 of an inch. 



Habitat. Garden Island, Port Jackson, &c. Cox. 



Specimens of a shell from Garden Island, Port Jackson, in my col- 

 lection, so thoroughly agree with the description of Ferrusac of IT. 

 capillacea, copied in Pfeiffer's Hon. LTel. Yiv., Vol. I., p. 90, and as 

 perfectly with the three figures in the original plate, with which I 

 have carefully compared them, that I have not the slightest hesi- 

 tation in referring them to that species originally stated as from 

 Port Jackson. And as this is merely one of the forms of a very 

 variable species, long afterwards named H. Strangei by Pfeiffer, the 

 latter name should be regarded as a synonym. However, to com- 

 promise the matter, I here beg to include under the head DT.
