smith: on the genus vanikoro. 117 



The following species are referable to other genera, or are beyond 

 recognition : — 



1. Vanikoro semisoluta, Sowerby: Conch. Icon., fig. 24. I consider 



that this species would be better located in the genus Fossarus. 

 Type in B.M. 



2. Narica tuberosisaima (Montagu), Recluz : P.Z.S., 1843, p. 136. 



This may be the very young stage of V. sulcata, but it is very 

 uncertain. 



3. Narica glaherrima (Brown), Eecluz : P.Z.S., 1843, p. 136. This 



appears to be a species of Neritina. 



4. Narica Mauritics, Recluz : Mag. de Zool., 1845, p. 19, pi. cxx ; 



Chenu, Man Conch., vol. i, p. 331, figs. 2403, 2405. Probably 

 merely the embryo of something. 



5. Naricai^.) atiomala, C. B. Adams: Contributions to Conch., p. 109. 



Is the type of Isapis. B.M. 



6. Na/rica ovoidea, Gould: Boston Journ. Nat. Hist., 1853, vol. vi, 



p. 380, pi. xiv, fig. 10. 

 Narica [Isapis) ovoidea, Gould: Otia Conch., p. 185. 



As intimated by the author in his " Otia," this species belongs to 

 Isapis, in which genus, under the unfigured (!) forms, it appears in 

 Try on' s work. 



7. Narica scalaris, Recluz : Lienard, Cat. Faune Mai. Maurice, p. 47 



(1877). Recluz has not described such a species. 



8. Vanikoro gracilis, Brazier: Proc. Linn. Soc. N.S.W., 1894, p. 169, 



pi. xiv, fig. 4. 



This species has been shown by Hedley to belong to the genus 

 Couthouyia (op. cit., 1900, p. 506, pi. xxvi, fig. 13).
