European Miocene material, and find all gradations between these 

 forms. The platelike costae, broken into numerous irregular, jagged 

 portions are very. characteristic of the variety, and by this character 

 Glohulina gibba var. striata can easily be distinguished from the allied 

 forms such as Globulina gibba var. ornata (Karrer), and var. myristi- 

 jormis (Williamson). 



Plate 16, figure 5, is from a paratype of Egger's, and figure 7 is from, 

 Ortenburg, Germany.

Variety having the wall marked by numerous longitudinal costae 

 usually interrupted at the sutures and occasionally broken, especially 

 in the basal area. 



Length 0.30-0.40 mm.; breadth 0.25-0.35 mm.; thickness 0.25- 

 0.35 mm. 



Globulina sulcata, named by d'Orbigny in 1826, but figured much 

 later by Fornasini, is undoubtedly the same as the present variety. 



There are specimens in our collections from the following: 



Recent. — Ireland, Steam Tug Lord Bandon, log. 33, Nymph Bank, 

 south of Cork, 52 fathoms; log. 11, southwest of Ireland, 38-44 

 fathoms. England, off Plymouth. Italy, beach, Lido, Venice. 



Pliocene. — England, Crag of Sutton. Italy, Castel Arquato. 



Miocene. — Austria, Baden and Nussdorf. 



Eocene. — France, Lutetien moyen, Grignon. 



It may be noted that specimens from the Eocene of Grignon have 

 very heavy costae as do also those of the Crag of Sutton.
