This form is very abundant and occurs at nearly all the 

 Stations in both Areas. The surface of the test, normally smooth, 

 is often more or less rough, and without a break passes into that 

 of U. aculeata. 



The typical form is common, but the specimen chosen for 

 illustration represents an interesting variety which occurs only at 

 Station 22 in Area 2.

This is just as plentiful as the smooth form, U. canariensis, and 

 the distribution is identical. It may be noted that at the individual- 

 Stations the relative abundance of the two forms is invariably the 

 same. 



The disposition to become uniserial is shown in many examples, 

 and in this respect they resemble the var. ampullacea of Brady, 

 which is described as a dimorphous U. asperula, connecting the 

 Ucigerinm with the Sagrince.

In the Malay Archipelago this variety of U. asperula is very 

 rare, and is confined to Area 1. 



Brady names nine localities where it has been found, the depths 

 ranging from 350 fathoms to 725 fathoms ; Egger records it from
