According to Coues 1882, Calypte is a proper name (cf. Gr. myth Calypso, island-dwelling daughter of Atlas who bore Ulysses two sons);"CALYPTE COSTÆ.  Costa's Calypte.   ...   Here we have a very beautiful little bird, conspicuous not only for the rich brilliancy of its head and throat, but for the colouring of those parts being of an unusual hue - a glittering metallic-lilac, neither easy to describe nor to depict, and which can only be feebly represented even with the aid of silver and the finest copal colours   ...   CALYPTE ANNÆ.  Anna's Calypte.  ...  CALYPTE HELENÆ.  Helena's Calypte." (Gould 1856); "Calypte Gould, Monogr. Trochil., pt. 11, May, 1856, pl. [5, 6, 7] and text [= 3, pl. 134, 135, 136 of volume]. Type, by subsequent designation, Ornismya costae Bourcier. (Baird, Brewer and Ridgway, Hist. No. Am. Bds., Land Bds., 2, 1875, p. 453)." (Peters 1945, V, 136).
