278 PALAEONTOLOGY. 



n. sp., from the Wealden, is represented by a mandible, of which the 

 symphysis is wanting. It is assigned provisionally to the genus Ptero- 

 dactylus, of which P. longirostris is the type. The length of the ramus 

 between the articular surface and the posterior end of the symphysis is 

 estimated at 13 inches. The teeth are subsimilar, nearly equidistant. 

 Both jaws are believed to be broader and less compressed than in P. 

 compressirostris. — CoJohorhynchus davirostris, n. »p. A. Pterodactyle 

 from the Wealden, of the " truncirostral " section. " The small anterior 

 pair of premaxillary teeth project from the front surface of the bone, 

 and at a greater elevation above the palate and the sockets of the second 

 pair than in ColohorTiynclms Cuvieri or Coloh. Sedgwichii" — Fragments 

 of humeri from the Kimmeridge Clay are referred to P. Mansellii and 

 P. PleyclelUi. Phalanges of the " wing-finger " from the Great Oolite 

 are described under the names of P. Kiddii, P. Duncani^ and P. 

 Aclandi. P. Marderi, from the Lias, is described from the proximal 

 half of a humerus. — The distal end of a humerus of DlmorjpJiodon 

 macronycff is noticed. L. C. M.
