F0RAM1NIFEEA OF THE WEST OF SCOTLAND. 225 



Strongly marked isomorphs of Gloligerma bulloides are rare, the majority of specimens 

 being rather small and obscure, and comparatively flat on the superior face. Isomorphs 

 of Ololigerma inflata occur at Stns. 3 and 11. At Stn. 11 the best isomorph of 

 G. bulloides occurs. The general facies of the specimens is that of figs. 131-133, pi. v. 

 in Goes's memoir (G. 3891, ASF.).

Very generally distributed, often common. This little species appears to be one 

 of the most fixed in its characteristics of the genus. Practically no variation is 

 observable in the whole of these dredgings except in its relative abundance and its 

 development as regards size; the number of chambers and their proportions are 

 practically constant.

 varies at different Stns. : at some, notably Stn. 3, only light grey individuals ; at others,
