A fragmentary example (No. 4907), originally of about 200 mm. 

 diameter, but still septate at the end, shows close agreement with 

 Stoliczka' s large specimen and with the very similar False Bay form. 

 The dimensions probably were : 



Height of the last whorl . 46 per cent, of the diameter 

 Thickness . 39 



Umbilicus . . .25 ,, 



On the test, which is 1'5 mm. in thickness, the varices are not, 

 shown, but there is a labial ridge across the periphery, corresponding 

 Avith a sulcus on the cast, though this sulcus extends across the sides 

 as well. In addition to these ridges, which form a less acute sinus 

 on the venter than they do in P. bhima or P. pinyuis, there is faint 

 and irregular striation on the test. The presumably Cenomauiau P. 

 subtilis, Crick,* has very similar ornament, but is more compressed 

 (thickness = = 31 per cent.) and more involute (umbilicus = 20 per 

 cent.). P. pinguis, Crick, with a thickness of 36 per cent., appears to 

 be merely an inflated form of the subtilis type ; but since it may be 

 of Ceuonmnian age, and since the suture-line cannot be compared, its 

 exact relations to P. bhima must remain somewhat uncertain. The 

 larger fragment in the British Museum (No. C18243) is extremely 

 close to the specimen here described, and differs, apart from slightly 

 varying proportions, only in having more acutely linguiform ridges 

 on the periphery a character in which it is nearer to the Indian 

 species than to the specimen here described. 



P. insculpta, Kossmatf is more compressed, but the large examples
