between the two folds some obscure ridges are often observable. It chiefly 

 differs from the type in its smaller and narrower dimensions, as well as 

 possessing more regular plications within the labrum. From Eocene, examples 

 of Janiopsis, as recognised by M. Cossmann, l such as Turbine lla parisiensis 

 and Fusus herouvallensis, both of Deshayes, the African shell differs in 

 having a narrower axis, more produced spire, and distantly situated plications 

 on the columella, one being high up in the posterior region, while the other 

 is anterior ; moreover, in the Eocene forms both plications are anterior and 

 closely parallel to each other ; in those species also, the body -whorl is longer 

 than the spire. Such evidence, therefore, is in favour of the African shell 

 being more closely related to Upper Tertiary forms than to species of older 

 age it may be known as Janiopsis nigeriensis.

DESCRIPTION. Shell narrowly turriculate ; spire shorter than body-whorl, 

 with sub-angulose, convex, oblique and deeply sutured volutions ; elongately and 

 narrowly umbilicated, umbilical cavity with an outer, rounded, marginal inflation ; 

 mouth trigono-ovate, with a short and wide canaliculation at base ; labrum 

 internally plicated, external margin minutely and distantly dentated ; columella 

 slightly excavated, strongly triplicate, with three further obscure plications in 

 rear ; sculpture consisting of distant, longitudinally curved, swollen costae divided 

 by wide sulcations, outer surface entirely covered with closely-set, micro- 

 scopically fine, longitudinal striations, crossed by prominent equi-distant spiral 

 ridges.
