340 DISCOVERY REPORTS 



Often very common yet at times surprisingly rare. It is most common at stations 

 adjacent to the shores of the islands. The most usual type is a small flat evolute form, 

 neatly constructed, mica flakes being largely used. The micaceous constituent is especi- 

 ally noticeable at WS 92, where the specimens are so thin-walled as to be collapsing. At 

 WS 88 and 95 the specimens attain an unusual size for the area, and there is a complete 

 series ranging from the smallest to the largest, all the specimens being of the flat type. 

 At WS 71 , large specimens with turgid chambers are rare, and the usual small compressed 

 type is common, nothing intermediate between the two being found. It seems probable 

 that the two forms may represent the megalo- and microspheric types ; the Paris Type is 

 missing.

Twelve stations: WS 83, 87, 97, 98, 99, 109, 210, 215, 217, 219, 225, 248. 



Nearly all the stations at which the specimens occur lie to the north of the islands. At 

 the stations to the south of the islands the species is extremely rare. The best specimens 

 at WS 97-99 and 109.
