A single specimen of the megalospheric form is shown in the ac- 

 companying figure. There are other specimens that evidently are 

 microspheric, in which the proloculum is much smaller and the tube 

 much longer, as in Recent specimens. There seems to be no difference 

 between these Cretaceous forms and Recent forms from the same- 

 general area. Specimens were found attached to Ammodiscus pennyi, 

 Glomospira gordialis^ and Hyperammina elongata. These show that 

 the same general relationship of these genera was already definitely 

 present in the Upper Cretaceous. In the present oceans Ammolagena 

 clavata is often found attached to these genera and others of the 

 arenaceous group, as well as to some of the flattened calcareous forms. 

 This is another of the species that has kept its identity and its char- 

 acters at least since Cretaceous times without any distinct change 

 that is apparent.

The Cretaceous specimens, while most of them are distorted and 

 collapsed, have the general characters of the Recent species that 

 occurs often abundantly in the present ocean in this same general 

 region. Often the color of the Recent and Cretaceous forms is very 

 similar. It is somewhat difficult to distinguish this species from
