166 OBSERVATIONS ON THE CHAROPIDiE, 



Mr. Brazier, who examined these specimens at my request, fully 

 concurs with me in this opinion. 



The extended range we thus find possessed by albanensis is 

 sliared by its congener C. paradoxa, Cox, and as our knowledge 

 of the fauna of South-Western and South-Eastern Australia 

 improves, so may the affinity demonstrated by Hooker between 

 their respective floras be paralleled in the animal kingdom. 



These shells offer another illustration of the law pointed out by 

 Garrett* — that the most widely diflfused species of land mollusca 

 are always minute ; other instances are — Pu2m jmci/ica, Pfeiffer, 

 in Australia ; Stenogyra gracilis, Hutton, and Piqja pedicula, 

 Shuttleworth, in Polynesia ; Vallonia jiulchella, Miiller ; Vertigo 

 viuscorum, Linne ; Zonites fulvus, Draparnaud ; Z. viridulus, 

 Menke ; Z. nitidus, Miiller ; Acanthinula harpa, Say ; and Ferus- 

 sacia suhcylindrica, Liune, which range through the northern 

 ]>ortions of Europe, Asia, and America.

Shell thin, transparent; contour, a sphere truncated at the poles, 

 deeply concave above and below, the umbilical excavation deepest. 

 Colour brown, the shade of dry dead leaves, streaks of slightly 

 lighter shade represent the flame painting of other species. Wliorls 

 5, the earlier enrolled within the later and almost concealed by 

 them. From the channelled suture the last whorl rises perpen- 

 dicularly, then arches outwards to its summit, from which it 

 describes a curve of a third of a circle to its base, whence it 

 incurves to the umbilical crater. The characteristic involute 

 growth does not occur till the shell has attained a whorl and a 

 half, at which point the embryonic sculpture is interrupted (as
