— E. s. pickeringii and E. s. trilineata — may have to be united. 

 In my key of subspecies of E. sirtalis, the E. s. pickeringii was placed 

 inadvertently in section III, while it should have been placed in 

 section IV. 



Eutaenia sirtalis parietalis Say. 



Three from Hatzic, two from Sicamoos, B. C, and one from 

 Nelson and Vernon, B. C, respectively. Constant to its characters 

 in the interior, but the three specimens from Hatzic show an approach 

 to the trilineata form. This is produced by a diminution in the size 

 of the red spots anteriorly, and their obliteration on the posterior 

 part of the body and on the tail. 



Eutaenia elegans linealata Cope. 



Two from Tacoma, and one from Sicamoos, B. C. 

 Eutaenia elegans vagrans B. & G. 



Three from Nelson, B. C. 

 Crotalus confluentus lucifer B. & G. 



Vernon. 



Total number of species obtained, thirteen, of which eight are 

 batrachians and five snakes, two of the latter represented by two 

 subspecies each. 



An interesting feature in this collection is the remarkable exten- 

 sion of the northern range of the Spea hammondii intermontana, and 

 the Pityophis sayi bellona. The former had not been known pre- 

 viously north of Pyramid Lake, Nevada, and the latter, north of 

 the Humboldt River in the same State. 



Both are restricted to the Great Basin, and their northern range 

 indicates the extension of the fauna to a higher latitude than has 

 been hitherto known. This is consistent with the physical charac- 

 ters of the country, and with the indications furnished by the bird- 

 life, as I am informed by Mr. Rhoads. Another peculiarity is the 

 occurrence of Crotalus confluentus lucifer in the same region, instead 

 of the Great Basin form C. c. lecontei. The former is the coast 

 species, and has never been detected in the Great Basin. 



The species are distributed according to districts, as follows : 



PACIFIC COAST. 



Diemyctyhis torosus. 

 Hyla r eg ilia. 

 Rana ugilis aurora.
