As only spires of three specimens are available, full specific description 
cannot be given, but the characteristic and easily identified spire justifies 
the application of a specific name.

The aperture of this species is very like that of S. callosa. The = 
calloused pad surmounts the shoulder, passes the suture, and adheres to — 
the whorl above. Anteriorly the pad ends in a raised knob separated by — 
there are traces of fine spiral striae. As the tendency of the genus seems — = 
forms, this species appears to have reached a gerontic stage. К

Sizuthiolaria: sp. (c.) Struthiolaria vermis Group. A 
A single distorted shell from the Tawhiti beds, probably of Upper _ 
Miocene age, is of great interest, for it marks the first known appearance 
of this group in the Tertiary sequence. The ornamentation consists of 2 
and later 3 spiral cinguli on the spire-whorls, and so resembles that of 
S. tricarinata. The base has but 3 or 4 strong cords, a condition found only 
in the Lower Pliocene forms S. canaliculata, S. acuminata, and S. monilifera. _

Suter quotes, in the synonymy, Hector's figure of 1886. This, from ИЗ 
elongated outline, must have been drawn from a specimen of S. acuminata
