404 FUNAFUTI ATOLL. 



This species has its nearest kin in P. cinnamomea, Gould, but 

 differs so widely from that by contour, sculpture and exposed 

 nepionic shell that a new genus seems necessary to express the 

 distinction. Yet P. cinnamomea itself stands perhaps as far again 

 from the type of the genus P. crenulata, Broderip, and being 

 unable to offer any information on the animal of the new species, 

 I am unwilling to further divide a group of which our knowledge 

 is so brief. 



Scutellina of Gray (1847) being preoccupied by Scutellina of 

 Agassiz (1841), Pilsbry has substituted Phenacolepas.* 



TROCHUS OBELISOUS, Gmelin. 

 Pilsbry, Man. Conch, xi., 1889, p. 19, pi. ii., figs. 13, 14. 



Several specimens were taken alive in shallow water in the 

 lagoon associated with Mitra episcopalis. 



Fischer quotes this from New Caledonia, Fiji, Samoa and Tonga. 



TROCHUS TUBIFERUS, Kiener. 

 Pilsbry, op. cit., p. 31, pi. vi., figs. 62, 63. 



Two living specimens were found at low water on the western 

 side of the Funafuti lagoon. 



Fischerf gives as the range of this species New Caledonia, 

 Loyalty Islands, Upolu, Samoa, and Pilsbry adds Fiji. 



TROCHUS ATROPURPUREUS, Gould. 

 Pilsbry, op. cit., p. 77, pi. xi., figs. 28-32; pi. xiii., figs. 86, 87; pi. 



xv., figs. 50, 51. 



Not uncommon as dead shells on the lagoon beach. 

 Pilsbry notes this from San Christoval, Solomons, Tutuila, 

 Samoa and Fiji. In this Museum are specimens from New Cale- 

 donia and Tupuselei, Hood Lagoon and Milne -Bay, British New 

 Guinea. 



TROCHUS FASTIGIATUS, A. Adams. 

 Reeve, Conch. Icon, xiii., 1861, Trochus, pi. xv., fig. 87. 



Several dead specimens from the beach of the Funafuti lagoon. 

 Though described nearly half a century ago, the locality of this 

 species has not hitherto been announced. I have also collected it 

 at Panie, New Caledonia. 



GIBBULA CONCINNA, Dunker. 

 Pilsbry, op. cit., p. 230, pi. xl., figs. 8, 9. 



A shell plentiful at Funafuti and which I also saw at Nukulailai, 

 seems, though not agreeing exactly,- to be nearest this. The
