This is, I believe, one of the very few mollusks common to 
the European and Indian feas;I cannot separate the two 
forms even as varieties! A. Adams records F’. costatus, 
Brocchi, from the Mediterranean and China Seas; but F. 
ambiguus from Senegal only. 
2. Fossar tornatilis. 
Fossarus tornatilis, Gould, P. Bost. 8. 1859, Hongkong, at 10 fths.—azis 5,

Fide A. Adams, P. Z. 8.1863, should be Nerita costata, Broc., 
a Huropean species. Fischer, J. de C., 1864, separates the 
two forms. My brother also possesses the species from Ceylon. 
3. Fossar trochlearis.

Very likely a species of .Vanikoro ; unfortunately it is in 
very bad condition. It bears some resemblance to F’. reticu- 
latus, but is covered with very peculiar tubercles, &c., &c.
