XLIX.—Remarks on the Value of certain Cranial Characters employed hy Prof. Cope for distinguishing Lizards from Snakes. By G. A. BouLENGER, In a note in the September number of the ' American Natu- ralist ' for 1895 (p. 855) Prof. Cope has attempted to recharacterize the suborders Lacertilia and Ophidia on some cranial features which, I submit, are inadequate for that purpose. The bone I have hitherto termed Suprateraporal (Squamosal of many authors, Paroccipital of Cope), to wliich the quadrate is attached in most snakes, is stated by Prof. Cope in the Lacertilia to merely touch the latter bone, which articulates solely with the exoccipital; and he gives figures, taken from Varanus griseus^ illustrating this point. Prof. Cope has evidently contented himself with the examination of only a few types of Lacertilian skulls. It is otherwise inconceivable how such a general statement could have been made. In many Lacertilia the quadrate articulates with the squamosal and the supratemporal to the total exclusion of the exocci- pital ; whilst in some in which the squamosal is absent the articulation is with the exoccipital and the supratemporal (Uroplates), or with the exoccipital, supratemporal, and parietal {Gecko). I here give a figure of the bones in an. Suspensorium of Chlamydosaurus Kingii, from below and forwards.— eo, exoccipital; ^j, parietal; pro, prootic (petrosal, Cope) ; sq, squa- mosal (supratemporal, Cope) ; ste, supratemporal (paroccipital, Cope).
