5. Plirynosoma platyihinos Girard. One speciaieu from Bliss, Idaho, August 8; two — a male and 
a female — from the lava plains between Shoshone and the Snake River, August 7. In the 
latter locality the species was abundant. The two specimens there secured have the series of 
enlarged gulars almost obsolete, it being represented on each side by two or three scales slightly 
more pointed than the other gulars. The number of femoral pores is 8 in the male, 10 in the 
female. The tympanum is fully scaled iu one, only partially so in the other. 
6 . Ciiemidophoru.s tigri.s Baird & Girard. The “sand lizard” was the most abundant species iu 
Snake River bottoms. A single specimen wms collected near Bliss, Idaho, August 8. This 
seems not to differ from Owen’s valley specimens, and wo therefore follow Dr. Stejneger iu 
the use of the above name. 
7. Thamnoplii.s Vagrans (Baird A: Girard). Although the six garter snakes brought iu by the 
expedition show considerable color variation, they unquestionably represent a single species.

specimens, Clearwater River near Lewiston, Idaho, August 15; 1 specimen. Potlatch Creek 
near .1 uliaetta, Idaho, August 16 ; 1 specimen, Wardner, Idaho, August 18 ; 1 specimen, Umatilla, 
Oregon, August 23.

Spokane River near Simkane, in September, 1802, by Mr. A. J. Woolman. 
9. Crotalus lucifer Baird & Girard. A single specimen taken on the Snake River between Twin 
Palls and Shoshone Falls, Idaho. The rattler is saiil to be not ahTuidaut in that vicinity.
