Hay : Description of New Species of Turtles. 19 



The first vertebral scute is considerably narrower than the others. 

 The lateral borders of the second and the third are angulated. The 

 pectoral scutes occupy 24 mm. of the midline. 



No. 1570 of the Carnegie Museum is likewise referred to this species. 

 It was collected by Mr. Douglass at Cold Spring, Montana, in what 

 are regarded as Loup Fork beds. 



This species is dedicated to Dr. W. J. Holland, Director of the 

 Carnegie Museum. 



Testudo ed^e, sp. nov. 



(Plates VII-VIII.) 



The single specimen which forms the type of this species was col- 

 lected by Mr. O. A. Peterson, in Loup Fork deposits, at Running 

 Water, Sioux county, Nebraska. The specimen consists of the cara- 

 pace and the plastron, from both of which a portion of the right side 

 is missing. The catalogue number of the specimen is 1535. 



The shell appears to have been originally somewhat depressed, but 

 this depression has been exaggerated during fossilization. The length 

 of the carapace is 450 mm. The width was 380 mm. The areas of 

 the second and the third vertebral scutes are somewhat concave. On 

 the area of the first there is a low and elongated boss. The lower 

 border of the pygal is somewhat drawn in. There are in this indi- 

 vidual only seven neurals. The first and the third are four-sided ; the 

 second and the fourth, eight-sided ; the others, six-sided. Most of 

 the costal plates behind the first are wedge-shaped, the narrow ends of 

 the second, fourth, and sixth being directed upward ; the narrow ends 

 of the third and the fifth, downward. 



The first and the fourth vertebral scutes are narrower than the others. 



The plastron lacks but 5 mm. of being as long as the carapace. 

 The epiplastral lip is 55 mm. long and 90 mm. wide at the base. Its 

 inferior surface curves upward like a sleighrunner. The pectoral 

 scutes occupy 25 mm. of the midline. 



This species is named in honor of Mrs. Eda Peterson, of Pittsburgh. 



Stylemys nebrascensis Leidy. 

 Notwithstanding the fact that hundreds, perhaps thousands, of 

 shells of Stylemys nebrascensis have been collected in the badlands 

 of South Dakota, Nebraska, and Colorado, no skull of the species has 

 hitherto been found in connection with parts of the shell. In Prince- 

 ton University there is a portion of a skull, and there is said to be a
