38708. Two slabs, one containing an anterior, and the other a 

 posterior rib of a very large animal ; from Hoheneck. 



Purchased, 1864. 



38708 a. The proximal portion of a rib agreeing in size with the 

 preceding; from Hoheneck. Purchased, 1864. 



38694. A specimen which appears to be part of a very large abdo- 

 minal rib ; from Hoheneck. Purchased, 18G4. 



42830. An imperfect left humerus ; from the Muschelkalk, probably 

 of Wurtemberg. This specimen appears to accord fairly 

 well in relative size with the imperfect coracoids figured 

 by Meyer, op. tit. pi. xxxvii. fig. 1, and pi. xxxix. fig. 1, 

 and provisionally referred to N. giganteus.

Genus COINTCHIOSAURUS, Meyer \ 



Closely allied to Nothosaurus, but with the crowns of the cheek- 

 teeth clavate as in Simosaurus. 



Conchiosaurus clavatus, Meyer 2 . 



Syn. Nothosaurus venustus, Miinster 3 . 



The type and only known species ; about one half the dimensions 

 of Nothosaurus mirabilis. 



The type cranium is figured by Meyer in his ' Saurier des Mus- 

 chelkalk,' pi. x. figs. 2-4 ; and that of the so-called N. venustus in 

 figs. 5-6 of the same. 



The undermentioned specimens being the remains of the smaller 

 forms found in the German Muschelkalk, and agreeing more or less 

 nearly in relative size with the crania, it is probable that at least a 

 moiety of them are referable to the present species ; although some 

 of the smallest may belong to Lariosaurus. 



Ilab. Europe (Germany). 



40051. Ten imperfect and apparently associated vertebra ; from 

 the Muschelkalk of Nurnberg, liavaria. Two of the 

 detached centra (No. 40051 a) belong to the anterior 

 part of the cervical region, the larger having a length of 

 0,012 (0*46 inch) ; they show very distinctly the double 

 costal facets, of which the uppermost join the surface for 

 the attachment of the arch. The two specimens in which 

 the arch is still retained apparently belong to the pos-
