Hai. Frankland Island, North Australia (on trunks and 

 branches of trees) ; Macgillivray. 



This new and interesting species is chiefly distinguished 

 by the curious crumpling inwards of the upper margin of 

 the aperture. The oceUated marking of the shell is also 

 peculiar. 



Species 358. (Fig. a, b, Mus. Cuming.) 



Helix granulata. Hel. testa imperforatd, globosd, 

 tenuiier granulata, subaured vel rufescente, faicid fused 

 cinctd ; spird brevi ; anfractihus quinque nd sex, pln- 

 niusculis, ultimo viagno, itiflalo ; aperturd ampld, tu- 

 nalo-elliplicd ; peristomate parum refiexo, alio, mar- 

 gitie columellari emarginato, valdi dilatato. 



The granulated Helix. Shell imperforated, globose, 

 finely granulated, somewhat golden or reddish, en- 

 circled with a faint brown band ; spire short ; whorls 

 five to six, rather flat, the last large and inflated ; 

 aperture large, lunar-elliptical ; lip but little re-

 niwntibus, columellari umbilicum subamplum profun-

The bipaktite Helix. Shell umbilicatcd, globose, 

 somewhat inflated, minutely gramdatcd beneath the 

 lens, light fulvous, lower part mostly dark chi-«tiiu( ; 

 spire obtuse ; whorls seven, flatly convex, more or less 

 plicately wrinkled at the sutures, last whorl desrcnd- 

 ing in front ; aperture nearly circular ; lip efl^usc, re- 

 flected, margins approximating, colimiellar margin 

 half-covering the umbilicus, which is rather large and 

 deep.

Ilab. Percy Island, North Australia ; Macgillivray. 



This fine species, collected by Mr. Macgillivray during 

 the voyage of the Rattlesnake, presents a striking con- 

 trast of colour on that portion of the whorb, which being 

 covered in the order of convolution, only, therefore, shoir< 

 it on the last whorl.
