and measured from the extremity of the outermost toe to that of the innermost 

 about one inch and a half. The toes all curved in one direction, and gradually 

 decreased in size, and terminated with claws. The smaller and rounder prints 

 on the slab are Chelonian tracks. This specimen was found near Liverpool, 

 England, in the Trias (Keuper sandstone), and is in the Royal Institution of Liv- 

 erpool. Size, 2 ft. 11 in. x 10 in. Price, $4.00. 



No. 266. Protorosaums Spenceri, Meyer. 



Vertebrae and Ribs. This <; fossil Monitor of Thuringia" was for a long 

 time the earliest Reptile, known to Geologists. It was a powerful Lizard with a 

 large head shaped like a long, slender, obtusely pointed cone ; it had strong, 

 straight jaws armed with sharp teeth — about 18 on each side of the* upper, and 

 16 on each side of the lower jaw implanted in distinct sockets. The vertebra; 

 were of large size and slightly concave at both ends. Both limbs were penta- 

 dactyle. These vertebras and ribs were found in the bituminous copper-slate 

 (Lower Permian) at Uothenburg, Germany, and are in the Palseontological Mu- 

 seum of Berlin. Size, 9 x 6. Price, $1.25. 



No. 267. Homoeosaurus Maximiliani, Meyer. 



Skeleton, on slab. This little scaly Lizard had a relatively short body, 

 long neck, and strong, blunt teeth. The specimen is from the lithographic slate 

 (Upper Oolite) at Eichstadt, Bavaria, and is now in the Museum of the Univer-

No. 268. Homoeosaurus Maximiliani, Meyer. 



Skeleton, on slab. This specimen, belonging to the Tylerian Museum at

No. 270. Saphseosaurus laticeps, Meyer. 



Skeleton, on slab. The most marked departure from the lacertian type in 

 this Reptile is the more uniform length of the phalanges of the fore-limbs. It 

 closely resembles the Homceosaurus. This fossil was found in the lithographic 

 Slate at Kelheim, Bavaria, and belongs to the Tylerian Museum at Haarlem, Hol- 

 land. Size, 15 x 7. Price, $3.00. 



No. 271. PhytOSaurus Kapffii, Meyer. 



Skull and Lower Jaw. 

 This so-called herbivorous 

 Reptile was formerly known 

 under the generic title of^
