smith: on the genus vanikoro. 115 



Sai. — Bohol, Philippine Is. (Recluz). 



This species appears to be hardly separable from N. acuta, but 

 certainly is very distinct from V. Ugata, with which it is united by 

 Tryon. Sowerby's figure of Souleyetiana represents V. helicoidea, and 

 not the present species. Melvill & Standen state that it occurs at 

 Lifu, Ceylon, and the Paumotus Islands. 



29. Yanikoko Cuviekiana (Recluz). B.M. 



Narica Cuvieriana, Recluz: Mag. de Zool., 1845, p. 63, pi. cxxxiv, 



figs. 1, 2. 

 Vam/coro Cuvieriana, Sowerby : Conch. Icon., figs. lOa-J; Thes. Conch., 



p. 169, fig. 23 (bad); Tryon, p. 70, fig. 94 (copy of Thesaurus). 



^^3. —Probably South Pacific (Recluz). Type in B.M. 



The thread-like lines are peculiarly raised, very fine and numerous, 

 and rough to the touch, as described by Recluz. I am inclined to 

 think that V. rosea is the young state of this species. 



30. Vanikoko eosea (Recluz). 



Narica rosea, Recluz: Proc. Zool. Soc, 1843, p. 140; Rev. Zool., 



1844, p. 6 ; Mag. de Zool., 1845, p. 36, pi. cxxvi, fig. 1. 

 Vanikoro rosea, Sowerbj^ : Conch. Icon., fig. 15 ; Thes. Conch., p. 169, 

 fig. 3 (?) ; Tryon, p. 69, fig. 82 (copy of Conch. Icon.). 



Hab. — Moluccas. 



A very small species, or possibly only the young stage of the 

 preceding. Sowerby's description in the Thesaurus appears to be 

 correct, as far as it goes, but the figure he cites, fig. 15, evidently 

 represents another species. His fig. 3, which is rose-tinted, is possibly 

 a poor representation of rosea. 



31. Vanikoro delicata (Pease). 



Narica delicata, Pease : Amer. Journ. Conch., vol. iii, p. 282, pi. xxiii, 



fig. 25 (1868). 

 Vanikoro delicata, Tryon : p. 68 (as young of Ugata), fig. 72 (copy 

 of Pease). 



Hah. — Paumotus. 



Rather like V. Cuvieriana in form, but differently sculptured. It 

 has no relationship whatever with V. Ugata, of which Tryon con- 

 sidered it the young. V. Ugata has the upper whorls distinctly plicate 

 and never rose-tinted, and its form is more globose and the umbilicus 

 much narrower. 



32. Vanikoro cryptophila. Carpenter. B.M. 



Vanicoro cryptopliila, Cpr. : Cat. Mazatlan Shells, p. 262. 



^ffii.— Mazatlan, West Mexico. Type in B.M. 

 This is a very small shell, and might well be the young stage of 

 some larger species.
