This name appears in a paper of Latham’s published in 1848. To it is referred a vocabulary of Tolmie’s. The area where it is spoken is said by Latham to be 50° 30' and 55° 30'. The name has become established by long usage, and it is chiefly on this account that it has been given preference over the Naas of Gallatin of the same year. The latter name was given by Gallatin to a group of languages now known to be not related, viz, Hailstla, Haceltzuk Billechola, and Chimeysan. Billechola belongs under Salishan, a family name of Gallatin’s of 1836.
