Test subgiobular to broadly oval, rather convex on one side in the 

 microspheric form, more or less equally compressed in the megalo- 

 spheric form, slightly produced at the apertural end; chambers more 

 or less compressed, generally up to seven in the microspheric, four in 

 the megalospheric form, the later chambers more embracing on one 

 side, arranged in an almost triserial series, each succeeding chamber 

 more or less above the base; sutures not depressed, distinct; wall 

 smooth, thick, often with fistulose tubes; aperture radiate. 



Length 0.65-0.90 mm.; breadth 0.40-0.65 mm.; thickness 0.20-0.35 

 mm. 



This is a compressed modification of Glohulina gibba, and there is a 

 certain range of variation in its test. 



Glohulina acuta (Roemer), from the German Oligocene has a rather 

 elongated test with an acuminate apertural end, and in Glohulina 

 turbinata Terquem the test is rhombic with rounded edges. 



Glohulina aequalis d'Orbigny, of which both the originals and 

 paratypes were examined by Ozav/a, shows a wide range of variation 

 in its shape. 



Distribution. — Like Glohulina gibba and Glohulina inaequalis, the 

 present variety is widely distributed both geologically and geographi- 

 cally. We have specimens from the following localities: 



Recent. — Atlantic off Nymph Bank, South of Cork Harbor, Ireland, 

 b2% fathoms; Dogs Bay, Ireland; coast of Iceland. Mediterranean, 

 Rimini, Italy. Pacific, shore sand, Torquay, on Bass Strait, Vi'btoria, 

 Australia.
