Loukotka (1968) Several attested extinct Bororoan varieties were either dialects of Otuke or closely related: •
Covareca -
Santa Ana mission, Bolivia •
Curuminaca - Casalvasco mission, Bolivia • Coraveca (Curave, Ecorabe) -
Santo Corazón mission, Bolivia (unattested) • Curucaneca (Curucane, Carruacane) -
San Rafael mission, Bolivia (unattested) • Tapii -
Santiago de Chiquitos mission, Bolivia (possibly
Zamucoan) (See
Jesuit Missions of Chiquitos for locations.) Mason (1950) says the first four are "separate and very different", but Loukotka (1968) notes that nothing is known of Curave or Curucane (or of Tapii), that only 14 words of Curumina and 19 of Covare have been preserved.
Mason (1950) Mason (1950) lists the following varieties of Otuke: ;Otuke • Otuké • Covareca • Curuminaca • Coraveca (?); Curavé (?) • Curucaneca (?) • Tapii (?) Mason (1950) notes that Tapii may have been either Otukean or
Zamucoan. == Grammar ==
