about 9 tubercles on the body-whorl ; aperture ovate, outer lip 

 acute, polished within and marked with more or less transparent 

 bands. 



Hab. Throughout India, Burma, and Ceylon, and perhaps one 

 of the most widely distributed and variable of species extending 

 as it does from Morocco in the West to China and Australia in 

 the East. 



The principal Indian varieties would seem, according to Nevill, 

 to be as follows : 



Var. subcrebra, Nevill, Hand List, p. 241. 



"A subgranulose variety approaching M. crebra, Lea ; 



of a uniform straw-colour ; spire not much produced ; last whorl 

 convex, whorls 6-7." 



Alt. 22, diara. 775 mm. 



Nab. Baiidarawella, Ceylon. 



Var. layardi (Dohrn), Nevill, Hand List, p. 242. 



Melania layardi, Dohrn, P. Z. S. 1858, p. 135; Reeve, Conch. Icon, 

 pi. 15, sp. 104 ; H. & T., C. I. pi. 73, figs. 8, 9. 



Original description : Testa turrita, solidiuscula, olivacea ; anfr. 

 6-7 convexi, striis spiralibus, rugis longitudinalibus regulariter 

 ornata, ad suturam f usco-maculata : apertura ovato-oblonga, iritus 

 cseruleo-albida ; columella rotundata, peristomium valde product 11111, 

 arcuatum. 



Alt. 35, diam. 10 mm. 



Aperture : alt. 10, diam. 5 mm. 



Hab. Ceylon; S. Canara (Beddome). 



On the S. Canara specimen Nevill makes the following 

 remarks : 



" The first specimens, I believe, of this very characteristic variety 

 described from Continental India. They are a very fine form. 

 long. 33, diam. 10-} mm. 7 whorls." 



The dimensions given in the original description are those 

 of Dohrn's largest specimen, he gives them, together with the 

 following description, of a smaller form, thus : 



" Var. Minor, decollata, nigrescens. intus cserulea." 

 Alt. 22, diam. 7 mm. 

 Aperture : alt. 7, diam. 4 mm. 



Var. tigrina (Hutton), Nevill, Hand List, pt. 2, p. 242. 



Melania tigrina, Hutton. J. A. S. B. 1850. p. 658 ; H. & T., C I. 

 pi. 110, fig. 2. 



Original description : Shell devoid of apex, the spire being 

 invariably much eroded ; general appearance that of M. pyramis,
