282 Annals of the Carnegie Museum. 



writer has found time to complete the brief sketch of these interesting 

 remains, which is here given. 



The type (No. 963 Carnegie Museum Catalog of Vertebrate Fos- 

 sils) consists of two vertebrae ; a cervical rib ; the first dorsal rib of 

 the left side ; fragments of several other dorsal ribs ; an os pubis ; 

 twenty-five scutes in fairly good condition, and numerous fragments of 

 others ; and in addition several hundreds of comminuted fragments of 

 vertebrae, ribs, and bones of the skull, which furnish no contacts, and 

 defy efforts to successfully collocate them. Some of these fragments 

 are more or less water-worn, and consist simply of bits of bone which 

 were for the most part found by Mr. Utterback upon the surface, 

 where the skeleton had been weathered out, and trodden under foot. 

 Some of them suggest that they have been exposed to the action of 



fire, and this might well have been the case when 

 prairie-fires swept over the spot. 



Generic characters of Deinosuchus so far as 

 known. Great size, exceeding that of any other 

 representative of the Crocodilia thus far described 

 from North America. 4 Scutes massive and pos- 

 sessing great vertical height in comparison with 

 their breadth, many of the smaller scutes being 

 almost hemispherical, and some of the smallest 

 subglobose. Pubis straighter and less deeply

The specimen, which almost beyond a doubt is the seventh in the 

 dorsal series, is the better preserved of the two vertebrae which were 

 recovered. It is proccelous. At the extremities of the transverse

 abroad and has been unable to find in any of them the fossil remains of any crocodile 

 from North America equaling in size those here reported upon.
