292 EHYNCHOCEPHALIA.

 skeleton. The original is the type, and was obtained in 

 1854 from the Kimeridgian of Workerstzell, near Eichstatt, 

 Bavaria. It is described and figured by Meyer in the 

 < Fauna der Yorwelt— Eept. Lith. Schiefer,' pp. 106-108,

Genus SAPHEOSAURUS, Meyer \ 



Syn. Piocormus, Wagner 2 . 



Skull longer and narrower than in Homoeosaurus, with pro- 

 portionately smaller orbits. Twenty-two to twenty-six presacral 

 vertebrae, and usually 42 caudals. Meyer suggests that the anterior 

 caudals had no transverse processes. The species attain a much 

 larger size than those of Homoeosaurus. 



Sapheosaurus laticeps (Wagner 3 ). 

 Syn. Piocormus laticeps, Wagner 4 . 



Differs from the typical S. tMollierei, Meyer 5 , by its greatly in- 

 ferior size, the presence of 26 instead of 22 presacral vertebrae, 

 and in the relative length of the limbs. 



Hob. Europe (Erance and Germany). 



39354. Cast of a slab of lithographic limestone, showing the nearly 

 entire skeleton. The original is the type, and was 

 obtained from the Kimeridgian of Cirin (Rhone), Erance. 

 It is figured by Wagner in the ' Abh. k.-bay. Ak. Wiss.' 

 vol. vi. pt. 3, pi. xvii. ; and also by Meyer in his ' Eauna 

 der Yorwelt — Eept. Lith. Schiefer', pi. xiii. figs. 2, 3. 



Purchased, 1865. 



Genus APHELOSAURUS, Gervais 6 . 

 Skull unknown. Provisionally referred by its founder to the 

 present group ; from which, however, it may prove distinct. The 

 phalangeals are of the normal number.
