While Señor Pimentel gave credit to his informant, Señor Tenochio, he did not indicate the original source of the vocabulary; but the source may be defined approximately by a process of elimination: there is hardly a possibility that the terms were obtained from any tribesmen in Seriland, since they were all inimical to the whites, and since very few of them have ever known enough of the Spanish tongue to permit communication with the Mexicans; accordingly, it is practically certain that the Seri interpreter must have been either (1) a resident of Pueblo Seri or (2) an attaché of rancho San Francisco de Costa Rica (of which more anon); and in either case it would seem certain that the native informant could have been none other than the standard Seri-Spanish interpreter of the last half century—Kolusio. Indeed, Kolusio was, at the time, the only Seri habitué of Pueblo Seri possessing sufficient knowledge of the Spanish and enough intelligence and independence to “give his language”, and was one of the two frequenters of the rancho similarly equipped. Pimentel’s contemporary, Licenciate Manuel Orozco y Berra, contributed in important measure to systematic knowledge of the Seri, which he defined (apparently on the basis of the Tenochio vocabulary systemized and published by Pimentel) as a distinct linguistic family with two dialectic branches,[188] viz.: [188] Geografia de las Lenguas y Carta Etnográfica de México, Precedidas de un Ensayo de Clasificacion de las Mismas Lenguas y de Apuntes para las Inmigraciones de las Tribus, por el Lic.

I. _Upanguaima_, por los upanguaimas, en Sonora. 62. II. _Guaima_, por los guaimas, guaymas, gayamas, cocomaques, en Sonora. Orozco’s map assigns to the Seri family an immense area (recalling Villa-Señor’s “despoblado”) extending from just above the mouth of the Yaqui, northward to the thirtieth parallel on the coast, stretching inland nearly to Cucurpe, Opodepe, and Ures, and including Tiburon; the “Salineros” lying adjacent to the coast in the north, the “Tepocas” medially, and the “Guaymas” in the south, within this area. In elucidating the map he wrote, under the title “El séri.—El upanguaima.—El guaima”:
