THE collection from which this notice is taken was made 

 several years ago by Dr. Edward Palmer for the Museum 

 of Comparative Zoology. It contained twenty snakes, 

 nineteen lizards, three turtles, thirteen frogs and toads 

 and one salamander; in all, fifty-six species, represented 

 by several hundred specimens. Especial interest attaches 

 to it, because of the pains taken by the doctor to secure 

 series of young and old, and the care with which he fixed 

 the localities and the dates of capture. The scarcity of 

 new species or varieties is accounted for by the fact that 

 the same regions had been visited by the collectors of the 

 Mexican Boundary Survey. Yet, although the ground 

 had been so well traversed before this collection was made, 

 it contains a number of forms not previously included in 

 recent fauna! lists of their respective localities^ 11
