FUNAFUTI ATOLL. 



VENUS PUERPERA, L., var. LISTERI, Gray. 

 Reeve, loc. cit., pi. v., sp. 14. 



Several adult valves were taken on the lagoon beach; and what 

 seems a very young shell was caught by the tangles in forty to 

 eighty fathoms on the western slope of the atoll. 



VENERUPIS MACROPHYLLA, Deshayes. 



Sowerby, Thes. Conch., ii., 1855, p. 763, pi. clxv., fig. 20. 

 One small specimen taken boring dead coral in the lagoon. 



NARANIO LAPICIDA, Chemnitz. 



Sowerby, Thes. Conch., ii., 1855, p. 776, pi. clxvi., fig. 26. 

 Found boring loose coral blocks in the lagoon. 



Schmeltz quotes this from Yap, Pelews. Sowerby mentions it 

 from Australia ; though no doubt it occurs on the Great Barrier 

 Reef, I am not acquainted with Australian examples of the typical 

 form with posterior radiating ribs. A thinner, smoother form, 

 (var. divaricata] has been noticed in South Australia. A useful 

 index to the genus is given by Tryon.* 



KELLIA PACIFICA, sp. nov. 

 (Fig. 54). 



F.g. 54. 



Shell oblong, inflated, most glossy, iridescent by reflected light. 

 Equivalve, margins closed. Inequilateral to the extent of the 

 posterior being twice the length of the anterior. Colour milky on 

 the umbont s, cream on the ventral margins, with concentric 

 opaque and translucent zones. Sculptured by delicate unequal 

 growth lines which grow coarser with age. Beaks small, almost 

 touching, forwardly directed. Ventral margin straight, anteriorly 

 truncated, posterior rounded and dorsal gently curved.
