MILIOLINA CIRCULARIS, 121 



Miliolina subbotunda, Brady, 1884. Report ' Challenger,' p. 168, pi. v, figs. 10 



and 11. 

 — Goes, 1894. K. Svensk. Akad. Handl., vol. xxv, No. 9, 



p. 109, pi. xix, figs. 846— 847 h. With 

 synonyms. 



Characters. — This variable but sufficiently recognisable form was mentioned in 

 Part T, p. 11, as having occurred in the Crag at Sutton, but lost before it could 

 be drawn. A figure of another specimen is now given. 



Fig. 9. — Miliolina subrotunda ; magn. 50 diam. (After Brady, ' Challenger ' Report, pi. v, fig. 11.) 



Occurrence. — Miliolina, subrotunda is essentially a shallow-water form. It is 

 recorded from the Arctic Seas (Parker and Jones), from several localities in the 

 Atlantic, and from the French and English coasts. Geologically it occurs in the 

 Miocene of Vienna and Bordeaux, the Pliocene of St. Erth, and the Crag. The 

 Crag specimen was found at Sutton.

and pi. v, figs. 13, 14 (?). 

 — — Sherborn and Chapman. Journ. R. Microsc. Soc., ser. 2, 



vol. vi, pi. xiv, fig. 2. 



Characters. — This is a near ally of M. subrotunda, with a more convex shell 

 and more closely enwrapping chambers. 



Occurrence. — Miliolina circularis appears to be rare in recent seas, and to 

 be confined to comparatively shallow water. The ' Challenger ' records are 

 from Prince Edward's Island, Kerguelen Island, and the Bass Strait. As a fossil 

 it is recorded from the London Clay of Piccadilly, Oligocene of Hermsdorf, and 

 quite recently from the older Pliocene of St. Erth (Millett). The figured specimen 

 is-from the Coralline Crag of Suffolk, — exact locality unknown.
