272 FORAMIKIFEKAL ROCKS ON WEST COAST OF SANTO, 



and L./ormof<a, Schlumberger.* The characters shown by thin 

 slices of tlie tests in the rocks before us, as, for example, in the 

 saddle-like form, in the 4-rayed aspect in median section due to 

 twisting in process of growth, and in the invariable accompaniment 

 of a megalosphere, together with its association with shells of L. 

 insuke-nat'dis, lend support to this view]

[Description. — Some examples, probabl}- of the megalospheric 

 form, of an almost globular shape, with short regular peripherical 

 processes were met w^ith. At first sight they seemed suggestive 

 of a form of Tirioporas, but thin sections showed them to be 

 related to the above species.]

The pre.sent example, which occurred in sample No. 182, is a 

 left valve of a form of Bairdia most like the above species. In 

 outline, this valve is exactly comparable with B. foveolata, more 

 especially with certain specimens I have already obtained from
