A CONTRIBUTION TO THE HERPETOLOGY OF BRITISH COLUMBIA. 



BY E. D. COPE. 



The present paper records the species contained in two collections 

 made in British Columbia. The first and less extensive was made by 

 Dr. and Mrs. G. F. Bodington, at Hatzic in the Matsqui Country, on 

 the Frazer River, near to the Umted States line. The fauna is that 

 of the Pacific Coast. The other and more considerable collection 

 was made by Samuel N. Rhoads, of Philadelphia, during an exten- 

 sive exploration of the country, made in the interest of zoological 

 science. His route extended from Tacoma (Washington) to Vic- 

 toria on Vancouver Island, and thence to Ashcroft in the arid 

 region east of the Cascade Mountains. Then it led one hundred 

 and fifty miles north to Lake La Hache about lat. 52° ; and then 

 returning to Ashcroft it extended eastward to the western base of 

 the Selkirk Range at Sicamoos, and to Vernon a little further 

 south. Mr. Rhoads returned to Revelstoke on the Columbia River, 

 and descended that stream about two hundred miles to Nelson, on 

 Kootenay Lake. Thence he went east to Field, near the summit of 

 the Rocky Mountains. The species collected represent a great 

 variety of climate and altitude. Thus species from Tacoma and 

 Victoria represent the humid coast fauna, and those from Ashcroft 

 eastward, belong to an arid and elevated country. No species were 

 found as far north as Lake La Hache. The species from the Rocky 

 Mountains represent a more elevated and less arid condition than 

 those prevailing at Ashcroft.
