Rob. — Cardwell, Rockingham Bay, Queensland, Gould Island 

 in Rockingham Bay. (Mr. G. E. Beddome.) 



* Var. a. — Thinner, darker in color on the upper surface, gra- 



nulation finer, light yellowish band following the suture 

 spirally to the Apex. 

 Diam. maj. 13, min. 10|., alt. 8 lines. 



* Var. b. — Thicker, light straw yellow, upper surface granulated 



obliquely rugosely striated, keel more distinctly seen on the 

 periphery; peristome scarcely reflected at the columellar 

 margin. 



Diam. maj. 11 J, min. 9|., alt. 7 lines. 



The two varieties come from Gould Island, and are much 

 smaller than those from the Mainland. 



* 6. Helix Beddome, new sp., pi. 8, fig. 7. 



Shell umbilicated, globose, inflated, very thin, distinctly 

 obliquely striated, granulated from left to right, taking somewhat 

 of a zig-zag form, smoky yellow, with a chestnut band under the 

 suture, having a faint broad one above, giving it a darker color ; 

 body whorl from the periphery, dark chestnut ; spine somewhat 

 globular, suture smooth ; whorls 5|, slightly convex, slowly 

 increasing, the last roundly convex, descending a little in front ; 

 aperture nearly diagonal, roundly lunate ; peristome below 

 slightly raised somewhat in the form of a small obtuse callus like 

 tooth, bluish white, very little expanded or reflected ; margins 

 rather distant, joined by a thin bluish white callus ; columellar 

 margin broadly expanded and reflected on the umbilicus. 



Diam. maj. 23, min. 18, alt. 17 lines. 



Hah. — 20 miles north-west of Cardwell, Rockingham Bay, 

 Queensland, in the ranges at an altitude of 3,500 feet. 

 (Mr. G. E, Beddome). 



This beautiful shell is "very thin, the granulations on its surface 

 are distinctly seen with the naked eye, some run straight, 

 some oblique or zigzag ; the sculpture can only be compared to 

 a fine double cross-cut file. The species is allied in color to Helix 

 bipartita, Fer.
