THE MOLLUSCA HEDLEY. 461 



SISTRUM TDBERCULATUM, Blainville. 

 Tryon, loc. cit., p. 186, pi. Ivii., figs. 218, 220. 



Abundant in rock pools on the outer reef of Funafuti. 



According to Tryon this inhabits Hawaii. Schmeltz mentions 

 Rockhampton (Queensland), Samoa and Fiji. In this Museum it 

 is shown from New Caledonia and Lord Howe Island. 



SISTRUM CANCELLATUM, Quoy. 

 Tryon, loc. cit., p. 188, pi. Iviii., figs. 242, 250. 



Common in the rock pools of Funafuti. 



Tryon mentions this from Hawaii ; Schmeltz gives Fiji, Raro- 

 tonga, and Tahiti. A specimen from Fanning Island is contained 

 in this Museum. 



SISTRUM FISCELLUM, Chemnitz. 

 Tryon, loc. cit., p. 188, pi. Iviii., figs. 251 - 257. 



Not uncommon on the Funafuti beaches. 



Examples from Teste Island, Louisiades, New Caledonia, and 

 Hawaii are preserved in this Museum. 



CORALLIOPHILA CORONATA, Barclay. 

 Tryon, loc. cit., p. 210, pi. Ixvi., figs. 372, 373. 



One worn specimen was gathered on the beach of Funafuti. 



Melvill and Standen, who received this from Lifu, were the 

 first to record it from the Pacific. 



GALEROPSIS MADREPORARUM, Sowerby. 

 Tryon, loc. cit., p. 212, pi. Ixvii., figs. 389 - 391, 398; Pease, Am. 



Journ. Conch, iv., 1868, p. 112. 



Purpura porphyroleuca, Crosse, Journ. de Conch, xix., 1871, p. 

 322, pi. xiii., fig. 7. 



This species was found alive at Funafuti in crevices of living 

 coral, particularly MiUepora. 



Quoy and Gaimard report this from Tonga, Marie from Tahiti, 

 Gould from Wake Island and Samoa, and Melvill and Standen 

 from Lifu. It is also shown in this Museum from New Caledonia, 

 Hawaii, and Vate, New Hebrides. 



The description above quoted by Crosse corresponds so 

 well to Sowerby's, that his name may safely be reduced to 

 synonotny. 



MAGILUS ANTIQUUS, Lamarck. 

 Tryon, loc. cit., p. 216, pi. Ixviii., figs. 400-411. 



Two young shells were obtained alive in company with the 

 Galeropsis just mentioned. Tryon's remark " that all the species 

 that have been differentiated from M. antiquus must be regarded 

 with suspicion," has guided my determination. Nothing seems to 

 be recorded of the distribution of this species in the Central Pacific. 

 A specimen from the Solomon Islands is in this Museum.
