ART. 16 THE FORAMINIFEBA GENUS EHRENBERGINA CUSHMAN 5 



fathoms off North Cape, New Zealand. There are numerous records 

 for E. serrata in this region some of which at least may be E. mestayeri . 



The peculiar fused central region of the ventral side is very dis- 

 tinctive. 



Specimens from the Miocene of the Filter Quarries, Batesford, Vic- 

 toria, are very close to if not identical with this species. 



Chapman has very recently^ figured a specimen from the Upper 

 Eocene of New Zealand which he refers to Ehrenbergina serrata Ehren- 

 berg. While the figured specimen has spines on the central ventral 

 portion, it appears otherwise very much like E. mestayeri and it may 

 be suspected that E. mestayeri developed from such a form by the 

 loss of the spines. The size is very close also.

 ology, vol. 9, 1884, pi. 55, figs. 2, 3, 5 (?) (not 4, 6, 7).— Cushman, Bull.

Test triangle, chambers numerous, dorsal side nearly flat, with the 

 sutures broad but not raised; ventral side with a median furrow 

 with a series of fine spines at the inner angles of the chambers and 

 fine downwardly pointing spines on the peripheral angles; in end 

 view with the dorsal side forming the base of a triangle which is 

 truncated on the ventral side; aperture elongate. 



Length up to 0.60 mm. 



The figure and description in my Atlantic paper do not correspond 

 owing to an error and I am trying here to correct this. E. hradyi 

 Cushman should be applied to those specimens with finely spinose 

 basal angles as in Brady's plate 55 (figs. 2 and 3), and as I have 

 figured.* Plate 55, figures 6 and 7 of Brady should be referred to 

 the following species :
