80 ICHTHYOPTEKYGIA. 



between the pterygoids, in the centre of which is the long 

 styliform presphenoidal rostrum. The anterior processes 

 of the pterygoids are very long and narrow, and articulate 

 with the equally slender vomers, external to which are 

 the posterior processes of the premaxillae. This specimen 

 is noticed by Seeley in the ' Quart. Journ. Geol. Soc' 

 vol. xxxvi. p. 642. Tesson Collection. Purchased, 1857. 



32681. The hinder portion of a similar cranium, with the hinder 



part of the left ramus of the mandible attached ; from the 

 Upper Lias of Curcy. In the left orbit the original ob- 

 lique contour is still retained, and the ridges on the nasals 

 are more prominently developed than in the preceding 

 specimen. The form of the quadratojugal seems to have 

 been the same as in the latter. Same history. 



32682. The hinder portion of a considerably smaller skull, in a 



somewhat crushed condition; from the Upper Lias of 

 Curcy. The quadratojugal extended higher up between 

 the postorbital and supratemporal than in No. 33157, 

 reaching to the level of the summit of the quadrate, and 

 more nearly resembling the arrangement obtaining in the 

 type. In this specimen the premaxilla and lachrymal 

 unite to shut out the maxilla from the narial aperture.

32685. A mass of matrix containing the anterior portion of the 

 (Fig.) vertebral column, the ribs, and a considerable portion of 



one of the pectoral limbs, belonging to the same individual 

 as No. 33157. The conjoint atlas and axis are figured by 

 Owen in his 4 Liassic Reptilia,' pt. iii. pi. xxiii. figs. 2-5, 

 and pi. xxvii. figs. 3-5 ; the impression being given that 

 the two bones are separate. The tall neural spines and the 

 elongated centra of the vertebrae are well shown. Of the 

 limb the humerus is wanting, and the portion remaining 

 has been bent over upon itself. The notch in the radius 

 and first carpale of the second row is shown, but the 

 radiale is wanting. There are four longitudinal rows of 

 phalangeals ; and the whole paddle, although imperfect 

 distally, agrees precisely in all essential details with that 

 of No. 14553 (p. 73). Same history. 



32686. The centra and portions of the arches of twelve middle and 



posterior dorsal vertebrae, not improbably belonging to the
