Family TURRITELLIDM. 



Turritella triplicata Stud. — Three, of normal coloration. Medi- 

 terranean, West Africa, Canary Islands, Coast of Spain. 



Turritella (Haustator) columnaris Kien. — One, in poor 

 condition. Ceylon. 



Turritella (Zaria) duplicataL.* — Many, including some perfect 

 and large albino varities ; also var. f3. attenuata Rv. is present in all 

 stages of growth. Indian Ocean generally. 



Family LITTORINIDM. 

 Littorina scabra L. — Plentiful, of typical form. Including its 

 varieties, this species stretches nearly round the world, extending from 

 West Africa around to Arabia, but has not yet been found in the 

 Mediterranean Sea. Indian Ocean, China, Fiji, Sandwich, and 

 Philippine Islands, Mazatlan, Florida, Ceylon, Japan, West Coast of 

 Africa, West Indies, Polynesia. 



Family SOLARIID/E. 



Solarium delectabile Melv.* — Described in 1S93 from 

 Bombay specimens collected by Mr. Abercrombie. Our Madras 

 specimen is unmistakable, though not in prime condition. This dis- 

 covery extends the range of this very beautiful little Solarium, which 

 will probably be found before long distributed around the Indian 

 coasts. 



Solarium modestum Phil. — Two pretty specimens. This may, 

 perhaps, be a variety of S. perspectivum, from which it differs in the 

 colouring only. Society Islands, China. 



Solarium perspectivum L. — One specimen is more conical 

 than usual. It also occurs in statu juvenili. Amboyna, Indian and 

 Pacific Oceans, China, to Australia. 



Solarium pictum Phil. — One, rather worn. New Guinea. 



Family RISSOIIDsE. 



Rissoina (Phosinella) deshayesi Schwartz. — With some little 

 diffidence we name our solitary large clathrate Rissoina as above. 

 Singapore (in Mus. Brit, unnamed), Philippines. 



Rissoina ( Phosinella ) sp. — To some extent agreeing with 

 Lifu examples of R. quasillus M. & S., but coarser in texture. We 

 also have the same form from Thursday Island, sent in shell sand, 

 collected by Mr. Arnold Henn. 



Rissoina (Morchiella) thaumasia M. & S., vide antea, p. 31. 



Fenella cerithina Phil*. — Two, rather worn. A small, prettily 

 decussated species. Mauritius, Island of Rodriguez, Red Sea, 

 Persian Gulf, Japan.
