The contour of the terminal faces ofthese vertebrae agrees precisely with that of several of the 202 SATTROPTERYGIA. dorsals of C. trochanterius; the dimensions of one of thecentra are:—length 0,033 (1-3 inches), height 0,097 (3-8inches), width 0,112 (4-4 inches). Presented by J. O. Mansel-Pleydell, Esq., 1874. Specimens ivhich may belong to either of the two precedingspecies, or to C. truncatus (infra). R. 735. The imperfect left scapula of a very large individual; fromthe Kimeridge Clay of Kimeridge Bay. The extremelength is 0,560 (22-1 inches). This specimen accordsclosely with the imperfect scapulae from Shotover, figuredhy Phillips, op. cit. p. 377, diagram 177, as ischia, the.

The presentspecimen would indicate an individual of somewhatlarger size than the type of Plesiosaurus manseli. Thecontour of this specimen is very similar to that of thecorresponding element of the next specimen, and is totallydifferent from that of Pliosaurus. Presented by J. C.
