Ava, and Shan Hills. 



In Sowerby's Monograph of Cyclostoma, this shell 

 was confused with an Aulopoma (f. 42), and erroneously 

 identified with the Pterocyclos, figured by Chemnitz as 

 " Cornu-venatorium" (the Helix, c. v. of Gmelin's 

 Systema). 



7. C. speciosus, var. Philippi. 

 The lip of this well-marked form is peculiar for its 

 colouring.

Eastern side of the Bay of Bengal. 

 This is the shell which was at first referred by 

 Benson (Zool. Journ.) to the C. perdix of Broderip 

 and Sowerby (Zool. Journ.) a species from Tenasserim, 

 with four whorls and a low spire, which does not well 

 agree with the characters of C. perdix of Sowerby in 

 his monograph (Thes. Conch, vol. 1), or of PfeifFer in 

 Kuster's edition of Chemnitz.

Figure 8 is taken from a paler variety which is less 



common than the other.
