 xxix. p. 203, pi. iv. fig. 8. 



This form is well represented, and occurs abundantly at most 

 of the Stations in both Areas. The examples ore large and 

 usually have a clear patch on the septal face, similar to that found 

 in recent specimens of P. Hduerii. 



Pulvinulina ohlonga AVilliamson sp. var. carinata var. n., 



plate X. fig. 3. 



This is a well-marked variety, and differs from the type in 

 having an acute ridge down the centre of the septal face ; this 

 peculiarity causes the transverse section of the chambers to be of 

 a triangular form. 



It occurs at a few Stations, but in small numbers.

 and M.) Parker, Jones, and Brady, 1871, Ann. and Mag. Nat. Hist., 

 ser. 4, vol. viii. p. 173, pi. xii. fig. 143. 



This variety of the P. auricula group is so abundant in the 

 Malay Archipelago, and its characters so persistent, that it may be 

 worth while to record it under the name given to it by d'Orbigny. 



The chambers are ventricose, and the sutures limbate, and 

 formed of clear shelly matter. 



It is common at several Stations in both Areas.

Abundant at two or three Stations, and occurs at several others 

 in both Areas. All the examples possess the characters shown in
