Fi-eshwatei-- Shells of the Lomsiade Archipelago. 207 



This species is widely distributed, occurring- in some of the 

 islands in the Indian Ocean, in the Malay Archipelago, and 

 in many islands in the Pacific.

Auricula caffra, Kiister, Coucli.-Cab. p. 30, pi. v. figs. G-S ; Sowerby? 

 Conch. Icou. lig'. 53 (bad !). 



Hah. Pig Island, Louisiade Archipelago, under logs a few 

 feet above high-water mark {MacGilllvray, in Brit. Mus.) ; 

 coast of Natal and Ohetaroa Island {Kiister) j Philippines 

 i^Aclanis) ; Samoa Islands (Brit. Mas.). 



There is little doubt that this species is the Auricula 

 sciurt described by Lesson in the Voyage of the ' Coquille.' 

 The specimens from Pig Island I at one time (Proc. Zool. 

 Soc. 1885, p. 600) referred to jSl.fasciatus. 



B. Freshwater Species. 



Neritina diadema. Recluz, is the only species recorded from 

 these islands; but MacGiliivray, in tlie Voyage of the 

 ' Rattlesnake ' (vol. i. p. 213), mentions having met with 

 " three kinds of Melania, a JSfavicella, and five species of 

 iSeritina,^^ but he does not name them specifically. All of 

 these are in the collection of the British Museum with the 

 exception of two Neritinw. The following is a list of the 

 species at present known to me from this archipelago. Most 

 of them are found in the Solomon and other neiii-hbourin"- 

 groups oi islands, but some have a still wider range. No 

 references or distribution are added, as these can be obtained 

 in Brot's monograph of Melania and iu Martens's works on 

 Neritina and Navicella.
