SYNONYMY OF AND REMARKS ON OLD-DESCRIBEI> 



AUSTRALIAN MOLLUSCA, WITH NOTES 



ON THEIR DISTRIBUTION. 



By John Brazier, F.L.S., C.M.Z.S., &c. 



In the year 1854 Mr. William Swainson, in the Proceedings of 

 the Royal Society of Van Diemen's Land (Vol. iii. p. 38, pi. vi. 

 tigs. 1, 2), defined and described a new genus and species of 

 TrochidcE^ discovered by Dr. Milligan on the east coast of that 

 island ; he defined the genus as Asfele, and he says that on a 

 cursory glance it has every appearance of belonging to the beauti- 

 ful genus Calliostoma (Treatise on Malacology, p. 351, 1840). 



The genus may thus be defined from its shell : — 



AsTELE, Swainson, 1854. 

 " Animal unknown. Shell perlaceous ; pyramidical or trochi- 

 form ; unarmed, body whorl beneath convex. Columella none. 

 Umbilicus large, closed only by the terminal whorl of the spire. 

 Aperture broader than high, the margin of both lips thin." 



AsTELE SUBCARINATA, Swainson, 1854. 



" Shell broader than high ; whorls above scarcely convex ; 

 marked by 6-7 elevated, smooth, convex striae, which leave a 

 flattened margined rim at the top of each whorl ; body whorl 

 beneath marked with concentric grooves, which are decussated 

 near the umbilicus." 



"Colour pale fawn, or Isabella, clouded with faint transverse 

 waves of rufous." 



" Margin of the body whorl slightly carinated ; there is a depres- 

 sion between the margin and the second elevated striae on the 

 upper surface, the first, or that next the margin, being very 

 slender. The striae beneath assume the appearance of grooves, 

 which are wider apart as they approach the umbilicus ; and the
