the extremity of the snout ; tlie anterior part of the mandible ; 

 the atlas and axis and four other cervical vertebia^, with their 

 ribs, behind which are two more cervical ribs in their natural 

 position in the series, the vertebraj being wanting ; two or 

 three dorsal vertebrse ; dorsal and sternal ribs ; interclavicle ; 

 both coracoids ; the leit scapula; both humeri and ulna^ ; 

 left ilium; an ischium; right tibia; left fibula; numerous 

 dorsal and ventral scutes, some of the latter still united with 

 one another. 



The skull (PI. YIII. fig. 1) has been much crushed from 

 above downwards, the palatal boues being especially badly 

 broken. About 3—4 cm. of the end of the snout are wanting. 

 In its general outline the skull is gavial-like, the snout being 

 relatively long and slender. The supratempoial i'ossa^, 

 thougli a little larger than the orbits, are much smaller 

 than in the Teleosauridge. Their upper rim is roughly 

 quadrate in outline, but below this level they are rounded off 

 at the anterior and posterior angles by projections of the 

 frontal and parietal. The bony platform surrounding these 

 openings is wide posteriorly and externally, and the upper 

 surface of the bar between them is also of considerable width. 

 The orbits, which looked upwards, outwards, aiid forwards, 

 are oval in outline, being somewhat narrowed in front by an 

 overhanging prominence on the prefrontal. 



In front of the temporal fossa; the frontal {/>'.) sends out 

 broad lateral branches to join the postfrontals. Anteriorly 

 they form the hinder part of the orbital border ; in front of 

 this the frontal first joins the prefrontal, then terminates 

 anteriorly in a broad wedge-like point, thrust in between the 

 hinder ends of the nasals and extending forward to about 

 2 cm. in front of the orbit. The prefrontals [pr.f.) are sepa- 

 rated from the frontals posteriorly by a short suture running- 

 inwards from the orbital border nearly at right angles to the 

 long axis of the skull, while their inner border is nearly 

 parallel with it ; anteriorly they widen out a little and bear 

 a prominence which projects over the front of the orbit. In 

 this region they overlap the lachrymal, which unites below 

 with the maxilla and forms the actual anterior angle of the 

 orbit. The nasals {n.) terminate posteriorly in points Avhicli 

 are thrust in between the frontal and postfrontals to a little 

 behind the level of the anterior angle of the orbit. Ante- 

 riorly they diminish in width very gradually, and their 

 anterior ends probably just reach the facial processes of the 

 premaxilla3 {p.mx.), wliich were long and slender, though, 

 owing to the loss of the anterior part of the snout, the form 

 of the premaxillse as a whole cannot be determined. The
