NUCULITES ABBEEVIATUS (Sharpe). 



1856. Clcidophorns nbhjecicdiis, Sharpe, Trans. Geol. Soc, ser. 2^ 

 vol. vii., p. 212, pi. xxvii., fig. 3. 



The description of this species given by Sharpe is as follows : 

 " Shell transversely ovate with prominent beaks ; anterior and 

 posterior ends regularly rounded : internal plate [clavicular ridge] 

 very large and nearly reaching to the margin : hinge-line arched :. 

 teeth small. The external surface has not been seen. Length 

 f of an inch; breadth 1 inch." 



The most marked characteristic of this species is its short, sub- 

 trigonal form with its long clavicular ridge, slightly curved forwards.. 

 N. hranneri Clarke {(J-V-), is more elliptical in shape and appears- 

 to be distinct. 



There is one imperfect cast of this species in the present collection 

 on the same slab as Glossites aff. dej^ressus.

NUCULITES AFRICANUS (Salter). 



1856. Cleidoi^lioriis Africanus (Salter MSS.), Sharpe, Trans. GeoL 

 Soc, ser. 2, vol. vii., p. 211, pi. xxvii., figs. 2, 4 (?). 



There is one poor example (No. 104) of this species in the collec- 

 tion. Sharpe defined it as follows : " Shell transversely elongato- 

 oval, covered with unequal and irregular concentric lines and 

 wrinkles ; internal plate large ; hinge straight ; teeth small, vertical,. 

 and very numerous. 



The length of our specimen is about 38-40 mm., and thus is nearly 

 the same as that described by Sharpe, who gave its dimensions as 

 2J by 1^ inches. Ulrichf mentions this species as comparable in 

 size to his Bolivian species N. bencchci. It appears to me doubtful 

 if Sharpe was right in referring the second specimen which was
