Leiuperus marmoratus Dum. ct Bibr. 



From Vincocaya and Puno. 



Leiuperus sagittifer Sciimidt. 



Many specimens. From Arequipa, Juliaca, and Puno. From these ex- 

 amples a regular series leading from the one species to the other may he 

 selected. The existence of so many intermediates suggests that sagittifer 

 may be no more than a variety. 



Bufo chilensis Tscnunr. 



Many toads were collected under the impression that several species were 

 represented ; a careful examination and comparison includes them all in one. 

 The toad of the Titicaca Valley and the mountains differs from that of the 

 coast ; those of these localities are smaller, and have the black blotches nar- 

 rowed down to mere spots which makes them appear much whiter. There 

 is much variation in the coloration ; some have few spots and small, others 

 many, and others are so dark as to render the marks obsolete. Many are 

 rough with small spines, others are smooth. In some cases the warts are 

 greatly developed, in others the skin is quite free and glossy. "With the 

 cutaneous fold on the tarsus ; the very young are dark colored and have 

 yellow feet. From Arequipa, Vincocaya, Puno, and Carapata. 



REPTILES. 



Saukians. 



Fhyllodactylus gymnopygus Dum. et Bibr. 

 Taken from beneath rocks on the plains near Arequipa, Peru. 



Leiolaemus signifer Dum. et Bibr. 



Very common on the plains' around Vincocaya and Colca, at an altitude 



of 14,500 feet. 



L. maculatus Gray. 



Abundant on the hills around Lake Titicaca. None were found on the 



summits, where signifer was so very plentiful. 



L. Belli Gray. 

 Two examples presented by Col. E. A. Flint, were from the Cuzco Valley. 



Ophidians. 

 Tachymenis peruviana Tschudi. 

 We are indebted to Col. E. A. Flint for one young and three adults 

 from the Cuzco Valley. This species is quite variable. These examples 

 have eight upper labials, the eye over the fourth and fifth, and in three of 

 them there are two anteorbitals instead of one. The colors are of the usual 

 pattern and very distinct.
