108 PKOCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



"rather thin, with numerous thin ribs and spiral strise ; apex rather 

 acuminated," and this description agrees with his figure. On the 

 contrary, the true plicata is rather solid, and is coarsely and obtusely 

 plicate, the plicae extending over the whole of the body-whorl. More- 

 over, the spire is less raised than in the shell figured by Sowerby and 

 Tryon. 



V. plicata was not described in the Proc. Zool. Soc. as stated by 

 Sowerby.

 Hal. — Capul I., Philippines. Type in B.M. 



Allied to plicata, but more widely umbilicated, with the last whorl 

 less globose. Costae rather similar, but more oblique. Melvill & 

 Standen have recorded this species from Lifu, Loyalty Is. 



6. Vanikoko Monteouzieei (Souverbie). 



Narica Montr omieri, Souverbie: Journ. de Conch., 1879, p. 136. 



Hah. — Lifu, Loyalty Is. 



This species, which has never been figured, is ITS mm. in length, 

 rather strongly costate, and spirally striate upon and between the ribs. 

 The umbilicus is deep, rather broadly funnel-shaped. 



7. Vanikoko Gaimakdi, H. & A. Adams. B.M. 



Vanikoro Gaimardi, H. & A. Adams : Genera Moll., vol. i, p. 375.

 fig. 13; Tryon, fig. 91 (copy of Sowerby). 



jy«^.— Chusan. Type in B.M. 



A. Adams described this species under the name V. Quoyiana, and 

 not Quoyi as given by Sowerby and Tryon, nor was it a manuscript 

 name as stated by the former. The species is quite distinct from 

 V. Orhignyiana, with which it has been united by Tryon. 



8. Vanikoro foveol.4ta (Montrouzier). 



Narica foveolata, Montrouzier: Journ. de Conch., 1866, p. 138, pi. vi,

 Hob. — Art I., Loyalty Is. 



A small strongly cancellated species, about the size of V. Gaimardi^ 

 but with closer ribs and more spiral lirae. 



I Watson's Bay, New South Wales (Angas, P.Z.S.', 18fe7, p. 212).
