space widest on diameter at right angles to line of processes, absent 

 opposite the processes, beyond this space the markings irregular. — 

 Pant. Fossil. Bacil, Ung., p. 56, pi, xxix. fig. 293. 



Habitat : Kio de Janeiro (Griffin ! Grrundler) ; San Pedro 

 (Grove !) ; Szakal deposit (Pantocsek !) ; Chalky Mount, Barbadoes 

 (Griffin !) ; Galapagos Islands (Cleve !). 



Yar. suhpunctata. — Subcircular, diam. • 045 mm. Central space 

 circular, distinct, 0*005 mm. broad. Markings somewhat distant 

 striae, apiculi numerous, distinct, the circlet adjacent to the border 

 obvious, the clear area opposite to the transverse area absent. Pro- 

 cesses circular, extending from the border half-way to central area. —

The specimen figured by Schmidt (Atl., pi. cxxv. fig. 7) as 

 perhaps A. pruinosus var. must come here. It is quite distinct from 

 A. pruinosus. 



Habitat : Oamaru deposit, New Zealand (Griffin !). 



§ 5. LOCULATI. 



Clear areas between central space and processes. JMarkings closely 

 placed, granular or pruinose striae, apiculi distinct.

 pi. xii. fig. 35. 



Eoundly elliptical, major axis, from 0*1 to 0*1125 mm., about 

 1-jIq to If times minor. Surface with transverse median areas flat, the 

 outer ends indistinct, rounded, about • 0125 mm. from the circum- 

 ference, between the sides and each process a distinct concavo-convex 

 hyaline area surrounding the central sides of the latter, and from 

 0*0375 to 0*04 mm. in length, with rounded ends about twice as 

 broad as its median portion. Central space distinct, rounded, hyaline, 

 0*015 to 0*0175 mm. broad. Markings distinct, striae radiating and 

 diverging from the central space, on outer portion straight along the 

 diameter at right angles to line of processes, elsewhere slightly concave 

 towards the processes; between their outer ends and the border a 

 hyaline space narrowest or absent opposite the processes ; apiculi at 

 outer ends of transverse area, and forming a band close to border, but 

 interrupted opposite the processes. Processes 2, irregularly round, 

 about 0*025 mm. broad, with central portion minutely punctate. —
