The Cretaceous Fanna of Pondoland. 343 



Another allied species is B. asper, Morton," which differs in 

 having larger and transversely elongated tubercles. Bacnlites vagina, 

 Forbes, i belongs to the same group of species but is clearly distinct 

 from B. capensis.

Description. — The whorls of the involute part are rounded but 

 become somewhat flattened in approaching the evolute part of the 

 shell. Umbilicus rather large. The evolute part increases in 

 height only slightly in passing from the involute part towards the 

 aperture ; its sides are flattened, and its external margin is mode- 

 rately broad and rounded. 



The involute part is ornamented with a few strong, nearly 

 straight ribs which are continued over the external margin and 

 sometimes bifurcate ; one or two more ribs are intercalated at 

 the external margin. On the evolute part a few tubercles form a 

 row near the external border of the side of the shell, and each 

 tubercle is continued as a strong, rather oblique rib across the whorl 

 to the inner margin where another tubercle may be developed. On 

 the external margin there are smaller and fairly numerous ribs. 



Suture line : saddles broader than lobes, with rounded termina- 

 tions. Siphonal lobe deep, broader than the superior-lateral lobe 

 which is divided into two nearly symmetrical parts each having three 

 digitations of which the lowest is the largest. Inferior-lateral much 

 smaller than the superior-lateral lobe, and divided into two parts. 

 Siphonal saddle very broad, divided into two parts of which the 

 outer is much larger than the inner. Superior-lateral and inferior- 

 lateral saddles much smaller than the siphonal saddle, each divided 

 by a small lobe into two broadly rounded parts. 



Beviarks. — This species is known at present by one somewhat 

 imperfect specimen. It shows some resemblance to S. Meslei, de 

 Grossouvre, ]; from the Coniacian of France, but the height of the
