370 FORAMINIFERA OF THE CRAG. 



not far from Florence ; at the Pretora Majella and the Consuma in the Apennines ; 

 and at Caldiero, Granella, and Brendola, not far from Verona. Onr figured 

 specimen is from Sudbourne ; and, together with some others previously men- 

 tioned, pp. 364, 368, was probably derived from some older Tertiary strata.

 1. Radiolarlan ? Plate III, figs. 23 a, 23 b. 



The small orbicular fossil, PI. Ill, figs. 23 a, 23 b, is of uncertain alliance. In 

 1862 the explanation of these figures was "hemispherical shell of an organism 

 possibly allied to Dactyl opora ; a ' derived' fossil (?). Sutton." 



As figured, it appears to be thick-shelled, perforate, and spherical, much like 

 an Orbulina, but more like a Oenosphxra, a simple, lattice-shelled Radiolarian, 

 common in both the recent and fossil condition. Where a piece of the outer 

 shell had been broken away, the figure shows what seems like an internal mass 

 with a few short pillar-like rods. 



The specimen is unfortunately lost. Mr. S. V. Wood, who collected it, has 

 left a memorandum to the effect that it was " hyaline," and possibly this may 

 have had reference to a siliceous condition. 



Mr. F. W. Millett has lent us a MS. book by Mr. S. V. Wood, written about 

 1845, containing notes and drawings of Foraminifera from the Crag, and in it this 

 little fossil is sketched in outline, and thus described : 



" 1. Okbulina perforata, mihi. 



"T[esta] orbicularis], sphserica, laevigata, perforata, perforationi[bu]s 

 magnis, apertura — . 



" Shell globular, spheroidal, smooth and hyaline; strong, with very large and 



regular perforations; aperture . Diameter ■£$ of an inch [= 0*6 mm.].

" I have only one specimen of this species, which I have ventured to place in 

 this genus. It does not fully correspond in its generic characters, as the 

 openings are few and very large, and as wide as the spaces between them. They 

 stand in irregular quincunx, and are not more that eight in the half-circle [across 

 the hemisphere]." 



Thus, although the figures are referred to in the explanation of the Plate III 

 (1866) as " hemispherical," one was evidently intended to represent a spherical
