9. LEIOCEPHALUS ARENARIUS (Tschitdi). 



Four adult specimens from Chospiyoc, Iluarocondo River, April 

 20, 1915 (U.S.N.M. Nos. 60705-8), and one (U.S.N.M. No. 60811) 

 from Toranton, May 1, 1915; also one half-grown specimen (U.S. 

 N.M. No. 60810) from Ollantaytambo, 9,400 feet altitude, May 15,

Roux ^ has pointed out that L. rhodogaster Boulenger - is evi- 

 dently identical with this species. L. lineigularis Werner ' is appar- 

 ently another synonym. The type localities of L. rhodogaster and 

 L. lineigularis are very near together, and the descriptions of these 

 species are very similar. 



Ifl, TUPINAMBIS NIGROPUNCTATUS Spix, 



Two fine adults and one half-grown si^ecimen (U.S.N.M. Nos.
