Verconella dubia n. sp. (Plate 17, fig. 18.) 
. Shell of moderate size, very strong; spire less than aperture and canal ; 
whorls 6 besides protoconch, subconvex, flattened below suture, body- 
whorl contracted quickly at base, with long neck twisted to left and 
backwards; protoconch of 2 smooth volutions, in shape of a flattened 
ome; sculpture of 10 strong but short axial ribs with equal interstices, — 
extending from suture to suture on early shell, but later becoming shorter — 
and not extending over base of body-whorl, spiral sculpture of 7 strong — - 
threads with weaker one filling each interstice, body-whorl with over 20  . 
strong threads, also weaker ones between each pair; suture slightly undulat- _ 
ing; aperture oval, lightly channelled above, produced below into long narrow 
canal very slightly sinused at end; outer lip lightly sinuous, antecurrent - 
to suture, with sharp edge, but thickened and strongly toothed within; — 
columella fairly long, somewhat concave above, twisted below at junction -

Holotype in collection of the New Zealand Geological Survey. 
Height, 30 mm. ; diameter, 15-5 mm. 1 
Locality.—1093, blue clays, Kikowhero Creek, Ngaruroro River. 
Remarks.—The inner lip is the same as that of Evarne striata (Hutton), 
but the outer lip is thick and strongly dentate. Apart from the denticles 
round the aperture the shell resembles a Verconella, but a complete survey 
of the generie affinities would involve so many already-described species 
that it hardly comes within the scope of this paper. The ornamenta- 
tion resembles that of V. thomsoni, but that species has a straighter canal.

Locality.—1092, blue clays above Te Aute limestone, Maharakeke Road, 
one mile south of Pukeora Sanatorium, Waipukurau. :
