THURAMMINA ERINACEA Goes.

I have examined the material selected by Goes as belonging to 

 this species and am inclined to think that they are Radiolaria and 

 not Foraminifera at all. Radiolaria of this form and size are not 

 uncommon on both sides of the Pacific. The mounted specimens are 

 fastened to a strip of cardboard and are not easily examined, but some 

 of the specimens are plainly Radiolaria. 



Goes recorded this species from nine Albatross stations along the 

 west coast of Mexico and Central America in 557-1 ,S79 fathoms. 



Subfamily 3. HYPERAMMININ^E. 



Test consisting of a globular proloculum and a more or less elon- 

 gated, sometimes branching portion, but not divided into chambers; 

 free or attached, wall of various agglutinated materials. 



In this subfamily are included a number of genera with the above 

 characters common to all. The main distinction between such genera 

 as Ilyperammina, Botellina, Ammolagena, etc., seems to be in the 

 material of the test and the habit of growth rather than in essential 

 differences in the general form of the test. All are of agglutinated 

 material. In Sagenina the test is very much branched, sometimes 

 anastomosing, but in essential features other than its excessive branch- 

 ing seems to belong with the others of this family.
