Shell ovate-conoid, pale yellowish, streaked transversely with 

 brown, somewhat glossy, more or less irregularly decussated with 

 fine spirals, except on the last whorl. Spire convex, suture im- 

 pressed, apex acule. Whorls 8, convex, the last nearly equalling 

 half the entire length of the shell. Aperture elliptic ovate, white 

 or pale lilac within ; peristome straight, acute, the margins con- 

 nected by a callus on the parietal wall ; columella slightly concave, 

 truncate. 



Length 94, diam. 45 mm. ; apert. 48 mm. (Calcutta specimens). 



Hab. India : Calcutta (introduced) (Nevill). Madagascar ; 

 Mascarenes ; Seychelles ; Comoro Islands ; Zanzibar. 



A native of Madagascar, Achatina fulica was, according to 

 Lesson, introduced in Mauritius and Bourbon. In addition, it 

 has been recorded from the Seychelles, the Comoro Islands, and 

 .Zanzibar. Although not being, strictly speaking, a native of 

 India, it has been thought advisable to include it since it appears 

 to have established itself thoroughly. 



The history of its earlier transport is not known, but Benson 

 has placed on record how he carried living specimens from the 

 Mauritius to Calcutta, where they were turned loose. After his 

 return to England he received news that it had multiplied in 

 neighbouring estates and was spreading. Hutton took some 

 specimens from Calcutta to Mussoorie, where they continued to 

 breed, but a severe winter exterminated them. Dr. Annandale 

 reports that it is common in gardens in Calcutta and neighbour- 

 hood, and that it is said to be spreading in other parts of India. 

 Pilsbry figures a shell from the Botanic Gardens, Calcutta.
