Testudo inusitata, sp. nov. 

 (Plates III-IV. ) 



This name is applied to a specimen which was collected by Mr. 

 Earl Douglass, near Canyon Ferry, Broadwater County, Montana. 

 The horizon is regarded as being that of the Deep River, a portion of 

 the Middle Miocene. The number of the type is 311 of the Car- 

 negie Museum. 



The length of the carapace is 265 mm. ; the width, 200 mm. A 

 peculiarity of the species is found in the forms of the neurals. The 

 first is, as usual in Testudo, four-sided. Usually in species of this 

 genus one or more of the neurals behind the first is four-sided and 

 one or more eight-sided. In the present species all behind the first 

 are six-sided. 



The vertebral scutes are about one half wider than long. Their 

 sides are not strongly angulated. 



The epiplastral lip is 25 mm. long and 58 mm. wide at the base. 

 The hinder lobe is notched, as usual in the genus. The gular scutes 

 extend backward on the entoplastron. The pectoral scutes meet along 

 the midline a distance of 15 mm. Their outer ends are greatly 

 expanded. 



Testudo hollandi, sp. nov. 



(Plates V-VI.) 



The catalogue number of the type of this fine species is 1561 of the 

 Carnegie Museum. The specimen was discovered by Mr. O. A. 

 Peterson in the upper beds of the Loup Fork, near Running Water 

 Sioux county, Nebraska. The shell alone is preserved, and this is 

 considerably crushed downward. 



The carapace has a length of 305 mm. and a width of 280 mm. 



The first neural is oval ; the second and the fourth, octagonal ; the 

 third and the fifth, tetragonal. The proximal ends of the second 

 and the fourth costals are narrow, the distal ends very wide ; while 

 the proximal ends of the third and the fifth are wide, the distal ends 

 narrow. 



The plastron is 325 mm. long, being thus longer than the carapace. 

 J he epiplastral lip projects 28 mm. beyond the gulo-humeral sulci 

 and is 70 mm. wide at its base. Its greatest thickness is at a point 

 45 mm. behind the anterior border. The entoplastron is 61 mm. 

 ong and 58 mm. wide.
