On Cretaceous Cephalopoda from Znhiland. 261 



folds are not so coarse as they are in Baily's original fig. 5 c, 

 selected as type of the species by Woods. Also, whereas in Baily's 

 holotype (No. 11373, Geol. Soc. Coll., British Museum), and still 

 more so in the co-type, the folds are coarser on the dorsal than on 

 the ventral sides, the reverse is noticeable in the present example, so 

 that the latter may only be a variety of B. capensix, Woods, 

 resembling some of the larger examples mentioned under the descrip- 

 tion of that species. 



B. carinatiia, Binkhorst,* has a somewhat similar ventral aspect, 

 but in the specimen here described, tin 1 whorl section is elliptical and 

 evenly rounded.

Three fragments (No. 5463) agree with Baily's original speci- 

 menf and have merely fine striation, not nodes, agreeing in this 

 respect with B. faujasi, Lamarck, in Binkhorst B. vertebralis, 

 Montfort ('?), and with the large forms, B. oval-its, Say, and B. yrandis, 

 Hull and Meek. B. chicoensis (Trask), G-abb, a number of speci- 

 mens of which from Vancouver Island are in the British Museum, 

 has only a slightly different suture-line and altogether seems very 

 close. 



B. syriacus, Conrad, according to a number of more or less badly- 

 preserved specimens in the Egyptian Collection at the British Museum, 

 referred to below (and associated with B. cf. feres, Forbes, and B. cf. 

 leopoliensi*, Nowak), probably also represents a similar smooth form 

 of this group.
