A shell, of which there are in the British Museum three speci- 

 mens, collected by Mr. Thwaites, probably near Kandy, has been 

 identified by Pfeiffer as a variety of the present species. The 

 sculpture is, however, finely decussate, without the characteristic 

 furrowed markings of A. chenui, and the shells are scarcely 

 distinguishable from the Travancore variety or subspecies of 

 A. basilessa already described (p. 40) as A. enisa. 



Hemiplecta simoni is founded on the variety with a slightly 

 raised spire represented in pi. 27, fig. 4 of Hanley and Theobald's 

 ' Conchologia Indica.'

 below the periphery, and a circular brown area around the 

 umbilicus; spire convexly conoid, apex blunt, suture slightly

The typical form is rosy pink banded with chestnut. H. ganoma 

 is a straw-coloured variety with brown bands, and generally more 

 depressed. The type of H. ganoma measured 51, 41, and 26 mm. 

 in the three dimensions; a smaller specimen gives 41, 34, and 20.
