ossified, are not roughened as in the other species of Scaphiopiis. 

 It is nearest the S. varius (from near San Antonio, Texas). In 

 that species the vomerine teeth are entirely posterior to the internal 

 nares ; in this one 'they are between the posterior borders of the 

 same. The lips are not cross-barred as in the S. varius ; and the 

 superior region has two pale lines on each side. In S. varius these 

 lines are replaced by a coarse marbling. As compared with Spea 

 hammondi, this frog differs in its larger size, lighter colors, and 

 the presence of the superior pair of light lines. 



It represents the S. hammondi in more noi'thern regions, and 

 the complete cranial ossification and larger size mark it as a more 

 fully developed form. 



Rana halecina Kalm. From Provo. 

 Eana pretiosa B. & G. 



A variety without a trace of dorso-lateral folds, and of a uniform 

 dusky color above and on the sides. Lip not striped. The pos- 

 terior part of the abdomen and the inferior face of the thighs are 

 salmon-red. Skin smooth ; diameter of membranum tympani 

 three-fifths that of the eye. Salt Lake City. This is the most

Sceloporus consobrinus B. & G. Provo. 



7. Atlanta, Idaho. 



Atlanta is a small town situated on the headwaters of the 

 South Boise River, on the southern drainage of the Sawtooth 

 Mountain Range. The valley is quite elevated, and is shut in by 

 granitic mountains ; water and vegetation are abundant ; and the 

 snow lies on the ground late in the spring. During a short visit 

 there in 1882, 1 obtained the following species : 



Amblystoma epixanthum sp. nov. 



Nearly related to Amblystoma mac7'odactylum Baird,and to be 

 placed next to that species in an}' synopsis of the genus.^ Costal 

 folds twelve. No canthus rostralis. Upper jaw overlapping 

 lower. Tail strongl}^ compressed, as long as head and body to 

 groin. Head wide-oval ; its greatest width one-fourth its total 

 length to the groin. Digits all rather short; four phalanges in
