THE MOLLU8CA HBDLEY. 409 



DELPHINULA LACINIATA, Lamwrck. 

 Pilsbry, op. cit., p. 266, pi. Ixvii., figs. 1, 2, 4. 



I collected a single worn shell on the sandbank in the centre 

 of the Funafuti lagoon. 



It is recorded by Kiener* from New Ireland, by Melvill and 

 Standenf from the Loyalty, and there is a specimen in this 

 Museum collected by Pere Montrouzier at Woodlark Island, 

 British New Guinea. 



NERITOPSIS RADULA, Linne. 

 Tryon, op. cit., p. 82, pi. xxix., fig. 68. 



One dead shell was found on the beach. 



Melvill and Standen record this from Lifu. Specimens from 

 New Caledonia are described by Fischer. J 



NERITA ALBICILLA, Linne. 

 Martens, Conch. Cab. ii., 11, 1889, p. 25, pi. viii., figs. 1, 2. 



One living example, found in the lagoon. 



This species ranges south along the Australian coast to Sydney. 

 Von Martens cites Port Carteret, New Ireland, Solomons, New 

 Caledonia, Fiji, Samoa, Tonga, and Tahiti. A specimen from 

 Erromanga, New Hebrides, is in this Museum. 



NERITA MAXIMA, Chemnitz. 

 Martens, op. cit., p. 29, pi. vi., figs. 1-5. 



Two living shells from under stones between tides in the lagoon 

 of Funafuti. 



Von Martens quotes for this Jaluit, Marshalls, Fiji, Samoa, 

 and Tahiti. 



Specimens are in this Museum from Aneiteum, New Hebrides. 



NERITA PLICATA, Linne. 

 Martens, op. cit., p. 63, pi. x., figs. 6-10. 



This species occured at Funafuti in great profusion. The wave- 

 worn breccia of the outer beach, just above high tide, is its 

 favourite haunt. Here a hundred may be gathered from a few 

 square feet. Into any crevice they crawl and huddle together 

 like a cluster of Helix aspersa when hibernating. Their tenacity 

 is wonderful. Often when picking them out of a crevice in the 

 coral, I have pulled away the shell and found the foot and 

 operculum adhering to the rock, torn from the viscera left in the
