TrocJiammina glohigeriniforinis, noted later, on account of the dis- 

 tortion that takes place in fossilization, resulting in some very queer- 

 shaped specimens. The specimens described by White in the above 

 references are probably distorted forms of this species. His Trocham- 

 minokles irregularis is probably the megalospheric form, and T. 

 proteus the microspheric form. These may, however, be much dis- 

 torted forms of T. glohigeriniformis, and without seeing the original 

 specimens it is difficult for one to determine this, even if it might 

 then be possible. The distortion produced is often so great as very 

 largely to obliterate the original form.

This species was originally described from the Upper Cretaceous, 

 Navarro formation of Hunt County, Tex., where it is a common 

 species. It has also been recorded from the Upper Cretaceous of 

 western Canada in the above reference. Its distribution is very wide, 

 and it is one of those sjDecies that persist in leached material where 

 many of the calcareous forms have disappeared.

This species, described previously from the Velasco shale of Mexico, 

 occurs in Europe, Mexico, and Trinidad, and probably elsewhere. It 

 is somewhat variable and on account of distortion assumes various 

 shapes.

This genus has apparently not been recorded elsewhere in the Cre- 

 taceous. It is a somewhat broader, more globular form than the
