Metriorhynchus moreli, Deslongchamps 1 . 



Of considerably larger size than the preceding ; from which it is 

 readily distinguished by the outer border of the prefrontals being 

 much less convex, and the pitting of the posterior part of the frontals 

 very indistinct. 



Hah. Europe (Prance and England). 



32618. The imperfect hinder portion of the cranium, showing the 

 occipito-parietal region, the frontals, prefrontals, and 

 proximal extremities of the nasals ; from the Oxford Clay 

 (Middle Jurassic) of Yaches-Noires (Calvados), Erance. 

 This specimen accords precisely with the corresponding 

 region of the type cranium figured by Deslongchamps in 

 his ' Notes Paleontologiques,' pi. xxii. tig. 1 a.

 wanting the two extremities ; from Yaches-Noires. 



Same history.
