Tho throat is usually chestnut, and there are 

 ob.scm-o bauds under the epidermis as indicated by the 

 do.scriptiou.

Bengal ; Pondicherry, teste Belanger. 

 The only individual known to us agrees faii-ly witli 

 the drawing of Swainson, who liaving cited, as a 

 synonym, tlic A. rugosa of Sowerby's genera (which 

 looks more like globosa) induced Deshayes to identify 

 both with Ilia A. spha?rica (Encycl. Metli. Vers). Can 

 it be an abnormal form of the ne.xt species ?

Calcutta; EohUkhund; Orissa, &c. 

 A common shell which attains much larger dimen- 

 ! sions than here exhibited : occasionally its peritreme is 

 I tinted with orange red, so as to remind one strongly of 

 I Crouch's ideal of A. Guyanensis (Crouch, Lam. pL 

 15, f. 18). The A. rotundata of Say (erroneously 

 I described as American, but with a testaceous oper- 

 culum) is supposed to be a form of this species.

This is not the species so named by Lamarck (as the 

 Cyclostoma carinatum of Olivier) which belongs to the 

 sinistral genus Lanistos. It is cliietiy distinguishable 

 from the next species by the greater breadth of tlie 

 penult whorl, and the sharper sutural angulation.

C.vhin. [Malabar : Bombay. 

 Very closely allied to tho preceding, and not im- 

 probably a local variety. Yet the upper whorls of the 

 spire (which is more exsert^d) are rounded. The 

 young type of Eeeve's Malabarica (f. 67) does not 

 exhibit the flat infrasutural ledge referred to by 

 Philippi. The A. pallens of Philippi (Kust. ed. Chemn. 

 Ampul, p. 32 ) may possibly prove the variety we have 

 received fi-om Cashmire. Eeeve's A. canaliculata, said 

 to have been taken in Cashmire, seems tlie yovmg of 

 A. speciosa.
