134 REPTILES AND BATRACHIANS 



Originally described from Pesquiera Grande, and New 

 Leon, Mexico. The lack of details in the note by Professor 

 Baird furnishes a reason for those given above. 



EUBLEPHARIS VARIEGATED Baird; Blgr. 

 Monclova, Mexico. 



ClNOSTERNUM HIRTIPES Wagl., 1830. 



San Luis Potosi, Mexico. 



EMYS ORNATA Gray, 1831. 



San Pedro, Chihuahua, Mexico. 



Three young specimens in the collection differ somewhat 

 from the typical E. ornata. They have a rounded spot of 

 yellow at the upper hinder margin of the orbit ; behind 

 this a short distance there is a broad subelliptical spot of 

 the same color that is not connected with the yellow spot 

 in front, or the yellow streak behind it. In this posi- 

 tion E. ornala has a continuous longitudinal band. On the 

 lower jaw, a little in front of the angle of the mouth, these 

 specimens have an elongate spot with rounded extremities, 

 also disconnected. The median baud under the chin con- 

 tinues backward without a break. 



A fourth specimen, however, is unlike the preceding in 

 that the large spot, on one side of the head, is connected 

 with both the small one behind the eye and the streak on 

 the neck. On the other side of the head the large spot is 

 connected with the streak but not with the spot behind the 

 orbit, though extending a sharp angle toward it. This 

 specimen agrees, on one side, with E. arnata as figured by 

 Dr. Giinther in Biol. Cent. Amer. Kept., pi. 1.
