160 REPORT—1874. 
no proof that the vertebres and rib figured by Prof. Huxley really belong to 
Anthracosaurus. 
*,* Professor Huxley has described a “supratemporal foramen” in the skull of 
Anthracosaurus. It occurs on both sides of the only skull yet discovered, and is of 
elongate-oval figure, measuring 1°3 in. x “4 in.

Il. BRACHYOPINA. 
Brachyops, Owen. 
Skull (figure). Parabolic, rather broader than long*; muzzle rounded. Orbits. 
Situate far forwards, large, oval, converging in front. Cranial sculpture. Faintly 
radiate; lyra consisting of two shallow grooves, which converge as they pass for- 
wards from the squamosals to the posterior part of the interorbital space, thence 
curving outwards and again inwards in a sigmoid line; there is a trace of malar 
grooves.

Micropholis, Huxley. 
Skull (figure). Parabolic; postero-lateral angles produced backwards. Orbits. 
Large, oval, occupying the middle third of the skull, converging forwards ; inter- 
orbital space less than the transverse diameter of the orbit. Nasal foramina. 
Rounded, “ distant less than twice their own antero-posterior diameter from the 
anterior edge of the orbit ;” separated by an interval equal to the interorbital 
pie Mandibular articulation. Transversely elongate; postarticular process 
absent, or very short. Teeth. “ Very numerous and close-set, slender, conical, 
sharply pointed, and either straight or concave inwards; they are stronger in the 
lower jaw than in the upper, and in the anterior than in the posterior part of the 
lower jaw.”
