638 MR. G. B. SOWERBY, JUN., ON NEW SHELLS. [May 17, 



Long. 11, diam. 5 niillim. 



Hab. Port Blair, Andaman Islands {Major Wilmer). 



Resembling in texture the Mauritian C. scalata, but of a more 

 acuminated form, the sutural depression being narrow and deep. 

 The colour is light reddish brown within and without, slightly paler 

 on the ribs and nodules. 



7. OvuLUM viDLERi, n. sp. (Plate LVI. fig. 1.) 



Testa elongata, utrinque acuminata, fransversim striata, cerasina, 

 terminibus vivide aurantiacis, dorso medio gibbosiusculo, levissime 

 angulato, lavigato vel obsolete costato ; apertura angusta, antics 

 latior ; labium Iceve, antice subangulatum ; columella callosa, po- 

 stice conspicue uniplicata. 

 Long. 21, diam. 7 millim. 



Sab. Monterey, west coast of America (Mr. Vidler). 

 An Ovulum of an elongated form, of a cherry-red colour, with 

 bright orange extremities. The back is nearly smooth ; and the 

 ends are transversely striated. Several of the specimens brought by 

 Mr. Vidler are smaller, smoother, and more slender than the one I have 

 chosen as type. 



8. Cypr^a smithi, n. sp. (Plate LVI. fig. 8.) 



Testa ovata, crassiuscula, umbilicata, pallidissime cinerea, minute 

 fusco-flavescenti lenticulata, dorsi medio maculis duabus subqua- 

 dratis castaneo-purpureis picta, lateribus albis rufo-fusco pun- 

 ctatis, basi convexa, alba ; apertura modica, postice arcuata ; 

 denies labii circiter 16, breves, obtusi, albi ; columellce circiter 

 19, tenues, rubro-fusci. 

 Long. 19, lat. 10 millim. 

 Hab. North-west coast of Australia. 

 Specimen presented to the British Museum. 

 The chief character of this species is to be found in the teeth, 

 those of the inner lip or columella being more numerous and much 

 thinner than those of the outer, and of a reddish-brown colour. The 

 only other species presenting this character is C. pyriformis, which 

 is much larger, more pear-shaped, and an inhabitant of the Ceylon 

 coast. Looking merely at the back of the shell it would pass for 

 one of the robust Australian forms of G.fimbriata (of which I con- 

 sider C. macula of Adams a variety) ; but a glance at the mouth 

 at once reveals the difference. 



I have pleasure in dedicating this species to Mr. Edgar Smith, of 

 the Zoological Department, British Museum. 



P.S. — Since I read this paper, I have seen a shell in the British 

 Museum (labelled "Port Essington") which leads me to consider 

 Cgprcea smithi a variety of C. pyriformis. The shell is interme- 

 diate in size between the average C. pyriformis and the shell above 

 described, and has the shape of the former with the white base of 

 the latter.
