Common, aiid universally distributed, the best and largest examples at 

 Stations 8, 9, 16, and 36. This curious little form with a looped aperture is one 

 of the distinctive forms of the " Terra Nova " gatherings, many of the 

 specimens agreeing definitely with Brady's type, others with the starved thin-walled 

 specimens which have so long been associated in British records with P. karsteni. 

 Brady, who was first responsible for the addition of P. karsteni to the British 

 records (B. 1864, RFS. p. 470, pi. xlviii, fig. 15), must have been cpiite familiar 

 with these British individuals, and it is extraordinary that he should have copied 

 Reuss's fiigure of the thick-walled true karsteni type to illustrate the compara- 

 tively minute British form. The records of the two are prol^ably 'inextricably 

 mixed. Brady, in recording his new form P. exigua, makes no reference to its 

 occurrence elsewhere than in the North and South Atlantic, the Southern Ocean 

 and Pacific, and treats it as an essentially deep-water form.

With the exception of Station 7, confined to deep-water Stations. Specimens 

 rare except at Stations 16 and 22. At Station 16 it attains a very large size, 

 but the specimens are dead and eroded .shells.
