Affinities. — This species appears to be related to B. teres, Forbes," 

 but possesses an oval, instead of a circular or nearly circular section, 

 and fine ribs instead of gentle undulations across the siphonal margin. 

 B. teres is found in the Valudayur Group of Pondicherri. 



Bemarks. — B. Bailyi is easily distinguished from B. sulcatus by 

 the character of the ribs. The specimen figured by Baily may be 

 taken as the type of the species. Several other specimens vs^ere 

 collected by the Survey and by Griesbach. The ribs are not so con- 

 spicuous as they are represented in Baily's figure. 



Baculites capensis, sp. nov. 

 Plate XLIV., figs. 6, 7. 



Description. — Shell large, increasing in diameter very slowly. 

 Section ovate ; sides flattened. Siphonal margin rounded, narrower 

 than the anti-siphonal margin. On each side of the shell, at a short 

 distance from the anti-siphonal margin, there is a row of large, blunt 

 tubercles which are elongated longitudinally. The surface of the 

 shell is ornamented with small, rounded, sometimes indistinct 

 transverse ribs ; in passing from the siphonal margin on to the sides 

 they bend rapidly backwards, thus becoming very oblique, but at the 

 level of the row of tubercles they curve round and pass forwards 

 over the anti-siphonal margin where they form a broadly rounded 

 fold. Just above the row of tubercles, at about the middle of the 

 shell, there is a shallow longitudinal sulcus. 



The largest specimen is 24 mm. in height and 18 mm. in width. 



Affinities. — This species is closely allied to B. incurvatus, 

 Dujardin,t which occurs in the Senonian of Europe, but it differs in 

 having a longitudinal sulcus on the side of the shell, and in the 

 tubercles being elongated instead of rounded. There are also some 

 small differences in the sutures.
