270 SAUK0PTERYGIA. 



the shortness of the mandibular symphysis this specimen 

 differs from the mandible of the type skeleton of the 

 latter, and agrees with the preceding specimen. Owen 

 states that the locality is Charmouth. No history. 



R. 1370. Part of the parieto-frontal region of a skull, apparently 

 agreeing with the corresponding portion of No. E. 1338 ; 

 from the Lower Lias, locality unknown. The ridge 

 dividing the supra-temporal fossae is nearly entire, while 

 the parietal foramen is quite perfect. No history. 



R. 1339. Two casts of the opposite sides of a slab showing the 

 greater portion of the skeleton, without the head. The 

 original specimen is the type, and was obtained from 

 Charmouth; it is preserved in the Museum at Bristol, 

 and is figured by Sollas, op. cit. pi. xxiii. Nearly the 

 whole of the vertebral column is shown, together with 

 the greater portion of the pectoral and pelvic girdles, and 

 the entire pectoral limbs. Of the pelvic limbs only the 

 femora are shown. No history. 



40140. Slab showing the two sides of an imperfect skeleton ; from 

 Charmouth. As exhibited in the case the slab shows the 

 oblique right lateral and ventral aspects, the left side of 

 the vertebral column being shown by a cast. There 

 remain 13 cervical vertebras in advance of the omosternum, 

 but to the extremity of this series there are appended 

 12 cervicals of another species, which are noticed under 

 the head of Eretmosaurus (p. 251), An imperfect cranium 

 is attached to the specimen, which may really belong to 

 it. The whole of the remaining portion of the vertebral 

 column is shown, together with the pectoral and pelvic 

 girdles, and the left humerus and femur. The specimen 

 is noticed by Sollas, op. cit. pp. 470, 471, who remarks its 

 close resemblance to the type, and also that there is pro- 

 bably some malarrangement in the cervical region, although 

 it was not suggested that the earlier vertebras were speci- 

 fically distinct. The anterior extremities of the coracoids 

 are wanting, but it is evident that, as in the type, these 

 bones did not overlap the omosternum to such an extent 

 as in P. hawJcinsi. This skeleton is noticed by Davies in 

 the ' Geol. Mag.' dec. 1, vol. i. p. 144, as the type of 

 P. laticeps. Purchased.
