A Revision of the Genus Auliscus Ehrb., &c. By J. Battray. 871 



Forma monocula Hardman M.S. — Subcircular, diam. • 07 mm. 

 Markings irregular, radiating, clear, faint lines ; apiculi few, chiefly 

 on a band near the border. Process 1, flat on central side " 02 mm. 

 broad. 



Habitat : Los Angelos (Hardman !). 



A. aceedens sp. n., Sch. Atl., pi. cxxv.-fig. 6 (without name). 



Subcircular, diam. • 08 mm. Surface rising slightly towards 

 the processes. Colour ? Central space small, rounded. Markings of 

 delicate radiating slightly flexuous striae, those converging to the 

 processes well marked ; apiculi numerous, distinct, absent from the 

 area bearing converging striae. Processes 2, circular, about ■ 02 mm. 

 broad, placed about half-way between the central space and the border, 

 or somewhat nearer the former. 

 Habitat : Gamaru (Weissflog). 



§ 3. Inflati. 



A prominent sharply defined central inflation extending between 

 the processes, widest opposite the central space. No transverse 

 median areas. 



A. injlatus Grove & Sturt, Journ. Quek. Mic. CI., 1887, p. 141, 

 pi. xii. fig. 37. 



Koundly elliptical, major axis 0'0875 mm., about l^g times 

 minor. Surface with the central inflation uniformly convex towards 

 the circumference, outside of it flat to border. Colour pale smoky 

 grey, darker along the margins of the inflation. Central space round, 

 distinct, ■ 0075 mm. broad. Markings striate, the striae converging- 

 to the processes delicate, the others radial, straight, or shghtly convex 

 towards the processes, sometimes slightly flexuous, more evident upon 

 than outside of the inflation, a faint reticulum near the border and 

 around the central space ; apiculi inconspicuous, chiefly around the 

 central space, near the processes few, and confined to the inflation. 

 Processes, 2, large, elliptical, major axis " 025 mm., about If times 

 the minor, their circumference smooth. 



Habitat : Gamaru deposit (Hardman ! R. Eattray ! Firth !). 



§ 4. MiRiPici. 



Central portion between processes more elevated than peripheral, 

 its edges distinct, constricted opposite the central space. Striae 

 sometimes geniculate at edges of elevated area. 



A. amoenus sp. n. 



Circular, diam. • 045 to • 0575 mm. Surface with central por- 

 tion sharply defined, suddenly constricted opposite the central space.
