Sve$bmus longipes Emerson and Loomis is much more com- 

 pletely known, as nearly the 'entire armor from neck to rump 

 is preserved as well as the skull, sacrum, and remains of the

 in which the long step and narrow trackway indicate a mam- 

 mal-like gait though the feet themselves were still typically 

 reptilian. A restoration of Stegomus longipes is here shown

The specimen of Rhytidodon validus described by Marsh as 

 Belodon is much more meagre, consisting as it does of a single 

 incomplete scapula. It pertains, however, to a very well- 

 known genus, abundant remains of which have been found 

 elsewhere than within the valley limitations, so that the entire 

 character of the animal is approximately known. This creature 

 was of decidedly more crocodile-like aspect, being comparable 

 to the modern gavials which inhabit the large rivers of India, 

 with their long attenuated snout and slender conical teeth. 

 Rhytidodon also doubtless resembled the gavial in its fish-eat- 

 ing habits, and the finding of such remains at Simsbury,
