Conus (Leptoconus) lyratus n. sp. (Plate XX, figs. 5, 5a.) 



Shell of moderate size, 28 mm. by 10 mm. Spire short, about one-fifth 

 the length of the body-whorl. Five whorls, each slightly convex in outline. 

 Each whorl rising by a decided step from the anterior suture. Aperture 

 narrow but expanding slightly anteriorly. Ornamentation : Whorls smooth 

 except for numerous distinct lines of growth which extend completely 

 across them. Body- whorl with distinct spiral lirae over its whole surface, 

 though they are more distinct in the anterior than in the posterior portion. 

 Lines of growth on the body-whorl are not numerous and not distinct. 

 A single specimen, in good condition. Type in the Wanganui Museum. 



Conus convexus n. sp. (Plate XX, figs. 6, 6a.) 



Shell of moderate size, 27 mm. by 13 mm. Spire conical, about one- 

 sixth the length of the shell, and consisting of 5 whorls. Outline of each 

 whorl convex. Aperture linear, narrow. Ornamentation : Whorls of the 

 spire lyrate with about 10 lirae, which are more pronounced on the anterior 

 than on the posterior part of the whorl. Lines of growth not distinct. 

 Body- whorl has fairly well-marked lines of growth, but it is otherwise 

 smooth except for some 10 spiral lirae near the anterior end. 



A single specimen, in good condition. Type in the Wanganui Museum. 



Conus (Lithoconus) abruptus. n. sp. (Plate XX, figs. 7, 7a.) 



Shell of moderate size, conical, 20 mm. by 11 mm. Spire of 5 whorls, 

 almost flat, and from it the protoconch of 3 whorls projects sharply. 

 Aperture narrow. Columella with a spiral groove near its anterior end. 

 Ornamentation : The whorls of the spire each with about 5 spiral lirae 

 crossed by numerous growth-lines. Suture moderately deep. Body-whorl 

 with numerous but indistinct growth-lines. Eleven distinct spiral lirae 

 near the anterior end. Otherwise the surface is quite smooth. 



One specimen, in good condition. This subgenus has not previously 

 been recorded from New Zealand. Type in the Wanganui Museum. 



Crenilabium zelandicum n. sp. (Plate XVIII, figs. 11, 11a.) 



Shell small, 10 mm. by 3 mm., tapering. Spire evidently short, but only 

 one whorl remains. Aperture more than half the length of the shell, narrow 

 below but rapidly widening in the middle. A short anterior canal. Outline 

 of whorl almost flat. Ornamentation : A series of rounded spiral lines 

 which extend to the anterior end of the shell. Columella with a thin fold. 

 One specimen only, somewhat imperfect. It is, however, certainly 

 rightly placed in this genus, which has not previously been recorded from 

 New Zealand. Type in the Wanganui Museum. 



Anomia poculifera n. sp. (Plate XXI, figs. 1, la.) 



Shell of small size : height, 25 mm. ; length, 18 mm. Shape rather 

 obtusely oval. Shell thin and inequilateral, with a nacreous interior. Right 

 valve strongly convex. Anterior end somewhat truncated, posterior end 

 somewhat longer. Foramen moderate, the processes united. Sculpture : 

 7 large rounded radiating ribs, somewhat bent, and extending from the 

 umbo to the ventral margin. Surface covered with small semilunar cups 

 just in contact with one another and with the convex side nearest the 

 umbo. Muscular impression large. 



A single specimen of the right valve, in good condition. Type in the 

 Wanganui Museum.
