 size. Drawn to measurement as if flat. 



Fig. 4. The same. Portion of the yellow froth-like substance, greatly- 

 magnified. «, thread-like extension of the same branched and 

 more or less charged with the opaque scarlet spherules iu line ; 

 h, scarlet spherules dispersed. Diagrammatic. 



Fig. 5. Discoid foraminiferal test, mucli magnified, showing scarlet 

 spherules in the chambers, a, spherule. From a microscopic 

 mounted longitudinal section of Loftusia persica. Nat. size of 

 test l-164th inch in diameter. Diagrammatic. 



Fig. 6. 3Iillarel/a cantabrigiensis. Microscopic slice from the centre of the 

 specimen, nat. size, indicating the transverse diameter of the 

 fossil. «, structure in the centre, composed of more or less 

 circular divisions interunited circumferentially by extensions of 

 the same material : b, pits or vacuities indicating the intervals 

 between the " extensions " where the " circular divisions " are 

 not well-defined. 



Fig. 7. The same. Portion of the centre, much magnified, to show the 

 mode of union of the circular divisions by the intervening " ex- 

 tensions (reticulated structure)." a, circular division ; 6, inter- 

 vening extensions. Diagrammatic. 



Fig. 8, The same. Circular division, still more magnified, to show the 

 character of the foraminiferal detritus with which it is charged. 

 a, " intervening extensions (reticulated structure) ; " bb, fora- 

 miniferal tests ; c, sponge-spicules ; d, discoid test, whose 

 chambers are filled with glauconite ; e, amorphous portion of 

 glauconite ; /, test in whose chambers respectively there is a

Head smaller than in S. nilgherriensis ; snout rather 

 pointed, rostral shield nearly twice as long as the vertical and 

 one third the length of the head, convex above, produced 

 back but not separating the nasals ; frontals somewhat 

 smaller than nasals, broad below, very narrow upwards 

 and only just meeting in front of the vertical ; eye rather 

 large, lying in the front of the ocular shield and occu- 

 pying a third of its size ; vertical diamond-shaped, longer 

 than broad ; caudal disk flat, not well defined, twice as long 

 as broad ; the terminal scute large, broad, and rough, mode- 

 rately bicuspid, the caudal scales prominently 2-4-keeled ; no 

 chin-shields between the first pair of lower labials and the 

 ventrals ; scales in 17 rows round the middle of the body and
