History. — Dicamptodon ensatus first came to the attention of 
naturalists in 1824 when Dr. Priedrick Eschscholtz, physician to the 
Russian explorer, Otto von Kotzebue, discovered a specimen in a foot- 
hill canon in central California. Eschscholtz accompanied Kotzebue 
on both of the latter’s voyages around the world and devoted much 
of his time while in port to collecting natural history specimens. On 
his second visit to California in September to November, 1824, in com- 
pany with Kotzebue he visited the Santa Clara Mission, sailed up the 
Sacramento River as far as the site of the present city of Sacramento, 
and made a trip from San Francisco to San Rafael Mission, thence 
overland to Fort Ross, returning by boat to San Francisco. The third 
journey was made early in October, between the second (or third) 
and twelfth of the month. It is probable that the “ Triton ensatus” 
was obtained at that time, somewhere in the neighborhood of Fort 
Ross in Sonoma County. Unfortunately the exact locality at which 
the type specimen was obtained must remain in doubt, for against the
