FOBAMINIFEEA OF THE ATLANTIC OCEAN. 81 



According to the author's description and notes it seems allied to 

 BatJiysiphon in the general characters of the test.

Description. — Test free, consisting of an ovoid proloculum with a 

 branching tubular second chamber, wall composed of sand grains 

 usually with the exterior roughened by projecting sponge spicules 

 incorporated in the wall; apertures formed by the open ends of the 

 tubular chamber. 



The genus erected by Eimer and Fickert for this species differs 

 from Uyperammina in its branching irregular habit and the typical 

 inclusion of sponge spicules in the outer portion of the wall. It 

 has a very wide distribution.

Description. — Test free, consisting of an ovoid proloculum passing 

 into a short tubular chamber, soon becoming branched, of nearly 

 uniform diameter throughout; wall composed of sand grains, firmly 

 cemented with numerous sponge spicules fixed in the outer layer, 

 giving a bristling appearance to the whole test; apertures formed by 

 the open ends of the tubular chamber; color reddish or yellowish 

 brown or gray. 



Distribution. — This is another of the very widely distributed species 

 of colder waters although it is not by any means limited to cold-water 

 areas as are certain other species. It is known from all the great
