Eiver deposits two imperfect fragments of a Turritelloid shell which 
he refers to Zaria (?) sp. showing somewhat similarly ornamented 
whorls but with fewer rows of spiral granulations and apparently less 
developed, besides having more depressed whorls and a considerably 
less distinct suture. The new form is also very distinct from Baily's 
T. honei from the Pondoland territory of South-East Africa (Quart. 
Joiirn. Geol. Soc, 1855, vol. xi.,pl. 12, fig. 7, p. 458), a species much 
more deeply sutured and ornamented with elevated spiral ridges 
which show no evidence of a granulated structure. Stoliczka's 
T. nodosa (Eomer) from the Utatur group of Southern India (Creta- 
ceous Gastropoda Southern India : Pal. Indica, 1868, pi. 17, 
fig. 7, pi. 19, figs. 20, 21, p. 222) shows spiral granulations, but the 
tubercles are much more closely arranged and nearly touching each 
other, whilst the whorls are more depressed and the suture is not so 
prominent.

Description. — This specimen is a matriciform impression associated 
in the same rock with Inoceramus chojfati. By the aid of a wax 
squeeze, its relationships to an Aporrhaiform- shell are at once 
apparent, but unfortunately only the basal whorl is preserved, the 
elements of the spire being entirely wanting. Viewed from the wax 
reproduction, the whorl is observed to lie in the dorsal position, 
exhibiting an oblique narrow and depressed posterior region suc- 
ceeded by a prominent horizontal peripheral margin from which 
extends horizontally a long, narrow, lateral spine ; the anterior part 
of the whorl contracts fairly rapidly from the peripheral angulation 
and is subsequently produced into a straight, narrow canal ; the 
surface sculpture consists of a series of close, equidistant spiral 
ridges, one of which, situated about 2 mm. below the periphery, is 
more elevated than the others and therefore forms a second 
angulation ; in the anterior region these striations are crossed by 
distant obscure radio-longitudinal striae ; the summit of the peripheral 
margin appears to be obscurely funiculated.
