This second species differs from 7. Braunii in the somewhat broader form of the 
skull, in the blunt anterior end of the palatine foramen, and in the backward posi- 
tion of the orbit, which, instead of lying anterior to the centre of the palatine 
foramen, falls in its posterior half. The orbits are not, however, so far back as in 
Capitosaurus. The differences between the two species are not due to difference of 
age; for 7. ocella is the smaller, and yet its distinctive peculiarities are such 
as increasing age would not diminish but exaggerate.

Skull (figure). Imperfectly known ; the small part preserved agrees in its general 
proportions with Zrematosaurus Braunit. Palatine foramina. Pointed in front, 
relatively more distant from each other and from the choanx than in Trematosaurus 
Braunii. Choane. Elongate-oval, approximated. Teeth (disposition). What is 
seen of the maxillary, palatal, and maxillary series is similar to the same parts of 
Trematosaurus. Mandibular articulation. The articular surface is concave forwards, 
and produced internally beyond the vertical plane of the inner surface of the ramus; 
a well-defined postarticular process. Cranial sculpture. A conspicuous group of 
pits and grooves upon each ossification. Lyra with distinct ee (directed out-
