2 1 take opportunity to state that the specimen of Sceloporus couchi, reported 

 by me from Devil's River, Texas (Proc. A . N. S., 1903, p. 540), proves to be the 

 subsequently described S. merriami Stejneger. I was misled by Baird's state- 

 ment of the number of femoral pores, which Stejneger finds to be erroneous 

 upon a careful examination of the type.
