This is, T believe, one of tlie very few moUusks common to 

 the European and Indian Seas ; I cannot separate the two 

 forms even as varieties ! A. Adams records F. costatuSj 

 Brocchi, from the Mediterranean and China Seas ; but F. 

 ambiguus from Senegal only.

Fide A. Adams, P. Z. S.1863, should be Nerita costata, Broc, 

 a European species. Fischer, J. de C, 1864, separates the 

 two forms. My brother also possesses the species from Ceylon.

Very likely a species of Vanihoro ; unfortunately it is m 

 very bad condition. It bears some resemblance to F. reticu- 

 latuSf but is covered with very peculiar tubercles, &c., &c.
