 Legrand's Col. for Mon., sp. 46. 



Shell openly umbilicatecl, depressly-obicular \ rather irregularly, 

 closely, and sharply striated ; reddish-brown ; spire flat, but not 

 excavated in the centre ; suture impressed ; whorls 4J, flattened and 

 slanting towards the suture, last tumid, not descending in front ; 

 umbilicus widely open, freely exposing the whorls- aperture round, 

 lips simple, thin ; margins closely approaching ; columellar margin not 

 reflected at the base. 



Variety a. — "White, occasionally pale yellow. 



Diameter, greatest 0*13, least 0*12 ; height 0-07 of an inch. 



Habitat. — Widely distributed : Mount Wellington, Launceston, 

 E,ingarooma, Circular Head ; also Victoria (?). 



Very much resembling H. iuloidea (Forbes), so widely dispersed 

 through Eastern Australia ; it may be but a variety of that species. 

 Around Launceston it is very common, and is more often to be got on 

 the exposed slopes of hills under stones and logs ; those found where there 

 is a dense moist herbage are generally paler in colour than the typical 

 form ; hence Mr. Brazier has named a variety of this description as 

 H. Eicei, and another specimen from Mount Wellington the same gen- 

 tleman has named IT. Onslowi, principally because the epidermis was 

 clearly shown. A species so generally distributed, as may be expected, 

 varies a little from what may be looked upon as the normal and typical 

 appearance. Some I have collected on the shaded banks of Kocher's 

 Creek are paler in colour, and have distinct coloured lines of growth. 

 Almost all the specimens I have seen, some hundreds, are more or less 

 decussate in the interstices — a character not noticed by Cox in his 

 description, and the umbilicus is scarcely ever so open as to freely expose 

 the whorls. It may be known by its orbicularly-depressed form and 

 striated surface. I have no doubt about the identification, as both Mr. 

 Brazier and Mr. Legrand have kindly sent me typical specimens got 

 from Dr. Cox. 



41. — Helix ( ) limula — Cox. 



Legrand's Col. for Mon., species 72. 



Shell perforate, thin, orbicularly-depressed, of a light brown 

 metallic colour, discoid ; thin, closely, and finely striately ribbed above 

 and below ; whorls 5, very gradually increasing in size, flat, last not
