allied form. It has the articular surfaces nearly flat, with the rims 

 sharp, the body is gently concave on the sides and below, from in 

 front back, and with stride near each rim for about half an inch. 

 The surface elsewhere is smooth and even, without venous foramina. 

 A transverse section through the middle wouhl give the greater part 

 of an elliptical figure, with the lower side somewhat flattened. Only 

 the base of the pedicels is present, and there is no indication of a 

 sutural union. Springing from them, or possibly from the body 

 itself produced above to meet the arch, there is on each side a stout 

 transverse process, the base only of which is present, but which 

 appears to be short. In shape and appearance, the centrum agrees 

 well with one of Hyposaunis rodgersi from New Jersey, except in its 

 more cylindrical shape. Its measurements are as follows: 



Length of centrum 40 mm. 



Transverse diameter of articulating face 50 " 



Vertical diameter of same face 38 " 



The upper end of a femur (fig. 4), found in the vicinity of the plesiosaur 

 paddle-bone which is figured, and which came from near the red beds, 

 appears to belong to the same kind of an animal as does the vertebra 

 described above. The shape is not unlike that of a human femur, 

 with the trochanters evidently small, and placed much below the level 

 of the head. The neck is stout, the head gently convex, with an 

 angular border. The shaft below the trochanters is somewhat flat- 

 tened from before back, but becomes more transverse below. The 

 shaft is hollow, with firm walls not more than one-third of an inch 

 in thickness. The portion preserved measures 210 mm., and I 

 suspect that the bone when entire was about 275 mm. long. The 

 diameter of the head is 50 mm., of the neck 40 mm., of the shaft at 

 the upper part 50 mm. and at the lower part 38 mm.

Postscript. — Since sending the above to the printer, I have 

 received a paper without plates published by Prof. F. W. Cragin, 

 May 12, in which are described and named a number of vertebrate 

 remains from the same beds. They all appear to be different from 

 those mentioned above, save possibly the Lamna.
