BRITISH FOSSIL REPTILES. 



of this species have been discovered in the Bath oohte at Bnslow, near Woodstock, 

 and in the oolite at Stonesfield. 



Teleosaurus Cadomensis (var.). — Of this species, which is nearly allied to, if not 

 identical with Cadomensis, I have examined a posterior cervical vertebra from the 

 oolite near Chipping Norton, in the collection of Mr. Kingdon of that town- 

 The sides of the centrum are less compressed than in the Tel. Ghapmanni, and 

 the articular extremities have a more circular contour, the transverse exceeding 

 the vertical diameter. There is no appearance of a ridge along the under surface : 

 the transverse process of the centrum arises close to the neurapophysis. 



The length of this vertebra is 

 Transverse diameter of centrum 

 Vertical diameter of centrum

Species — Teleosaurus brevior {CrocodiUa, PI. 16). 



In Teleosaurus Ghapmanni (PI. 15) the skull, from the fore part of the orbit to 

 the end of the snout, includes four lengths of the cranium behind that part of the 

 orbit ; in Tel. brevior the part of the skull anterior to the orbit includes but 

 two lengths and a half of the portion of the cranium behind that part of the 

 orbit. The upper temporal apertures are subquadrate, the longitudinal diameter 

 being the longest. The orbit is circular, but relatively smaller than in Teleosaurus 

 Ghapmanni; as in that species the plane of its outlet is more oblique than in 

 tertiary Crocodilia ; it combines a lateral as well as upper outlook. In tertiary 

 species only the upper third of the cavity is seen in a profile view (compare fig. 1, 

 PI. 16, with fig. 1, PI. 1 B, Grocodilus Hastingsioe). In advance of the orbits, in 

 Tel. brevior, as in the type species {Tel. Ghapmanni), are the orifices representing 

 the outer nostril in Enaliosauria. 



As in modern and tertiary Grocodilia, the hinder third of the mandible shows a 

 large vacuity; but the splenial element, 31 (fig. 13, p. 97, vol. i), enters into the 

 fore border of the vacuity in a larger proportion than in those later species. The 

 massive paroccipito-mastoid productions are proportionally shorter (compare 

 fig. 3, PI. 16, with fig. 2, PI. 1 a) ; the descending portions of the basioccipital are 

 also shorter in proportion to their breadth, and are more definitely notched below ; 

 the masto-parietals are longer, their free ends being more produced and slender. 



The proportion of the upper jaw retaining its smallest breadth is much less in 

 length than in Tel. Ghapmanni. The breadth of the produced slender portions 

 of both upper and lower jaws is relatively greater to their length than in Tel. 

 Ghapmanni. The teeth are similar in shape, relative size, and number, to those of 

 the type species, regard being had to the shorter jaws.
