408 FUNAFUTI ATOLL. 



Several empty shells from the lagoon beach. Hitherto only 

 recorded from the Paumotus. 



TURBO PETHOLATUS, L., var. CALKDONICUS, Fischer. 

 Pilsbry, Man. Conch, x., 1888, p. 194, pi. xlv., fig. 99. 



A few dead shells were collected on the beaches. 



This variety, of a peculiar colour pattern, and angled more or 

 less at the shoulder, is recorded by Fischer from New Caledonia, 

 and Anaa, Paumotus. A specimen in this Museum from the 

 Gilbert Islands shares this form and colour. Perhaps the typical 

 form is replaced in the Central Pacific by this variety. 



TURBO SETOSUS, Gmelin. 

 Pilsbry, op. cit., p. 195, pi. Ixiii., fig. 32. 



Abundant on the east coast of the atoll at low water on the 

 outer reef. 



Fischer cites this species from New Caledonia, Tahiti, Paumotus, 

 Marquesas, and Gilberts; Schmeltz adds Samoa. It is also shown 

 in this Museum from the Solomons. 



The opercula of the Funafuti examples agree with Fischer's 

 description,* but not with Pilsbry's, being white and smooth, ex- 

 cept on the distal margin, where they are brown and obliquely 

 wrinkled. 



TURBO ARGYROSTOMUS, Linne. 



Pilsbry, op. cit., p. 197, pi. xl., fig. 18; pi. xlii., fig. 41; pi. xlvi., 

 fig. 8. 



This species was less abundant ; it replaced the proceeding on 

 the western side of the atoll. Fischer indicates it from Tonga, 

 and from Anaa, Paumotus, and Schmeltz from Upolu. It is 

 represented in this Museum from the Solomons, New Caledonia, 

 Fanning Island, and Hawaii. 



ASTRALIUM PETROSUM, Martyn. 

 Pilsbry, op. cit., p. 234, pi. Ixiv., figs. 65, 66. 

 I found this alive in the lagoon. 



Pilsbry records this from New Caledonia, Fiji, and Hawaii. 

 An example from Woodlark Island, British New Guinea, is in 

 this Museum. 



LEPTOTHYRA LA ETA, Montrouzier. 



Pilsbry, op. cit., p. 258, pi. Ixiii., figs. 29, 30. 



Common on the lagoon beach at Funafuti. 



Pilsbry records this from Australia, Solomons, Fiji, and New 

 Caledonia.
