IV. DEINOSUCHUS 1 HATCHERI, 2 A NEW GENUS AND 



SPECIES OF CROCODILE FROM THE JUDITH 



RIVER BEDS OF MONTANA. 



By W. J. Holland. 



Upon the occasion of the geological reconnaissance undertaken 

 jointly by Mr. T. W. Stanton and Mr. J. B. Hatcher under the 

 auspices of the United States Geological Survey in the summer 

 of the year 1903, Mr. Hatcher found on Willow Creek, three 

 miles west of Nolan and Archer's ranch, in Fergus County, Montana, 

 some fragmentary remains lying upon the surface of the soil. He 

 picked up a couple of scutes, which he brought back with him to the 

 Carnegie Museum, and at the same time referred them provisionally 

 to Stereocephalns tutus Lambe. 3 Mr. W. H. Utterback was sent to 

 the locality by Mr. Hatcher in the fall of 1903 with instructions to 

 thoroughly explore the spot, and recover whatever could be found. 



Mr. Utterback only succeeded in finding two vertebrae, one cervical 

 rib, one fairly complete dorsal rib, fragments of other dorsal ribs, an 

 os pubis, a large number of scutes, some of them quite perfect, and 

 several hundred fragments of bones, some of them no doubt belong- 

 ing to the skull, others to the vertebrae and ribs, but all of them so 

 badly broken, and a few even water- worn, that it is impossible to refer 

 them with any degree of certainty to their true position. The verte- 

 brae and the ribs upon examination conclusively demonstrated, as the 

 writer pointed out to Mr. Hatcher, that the animal was a huge croco- 

 dile. Mr. Hatcher immediately lost interest in the material, and 

 though on several occasions urged to figure and describe the bones, 

 turned from them to other things, which at the time possessed greater 

 interest, and then came his untimely and melancholy end. 



In 1905 Professor S. W. Williston urged the writer to describe the 

 specimen, but, though the work was begun, it is only recently that the 



1 fitivdc; = terrible ; aovx<K = crocodile. 



2 1 take pleasure in naming the species after my associate and friend, the late Mr. 

 John Bell Hatcher, who was the discoverer of the specimen.
