(Nesospingidae; Ϯ Puerto Rican Tanager N. speculiferus) Gr. νησος nēsos  island (= Puerto Rico); σπιγγος spingos  finch  < σπιζω spizō  to chirp; "6. NESOSPINGUS SPECULIFERUS.  Chlorospingus speculiferus, Lawr. Ibis , 1875, p. 383, pl. ix, fig. 1  ...  Hab. Porto Rico.  This peculiar Antillean form can, I think, hardly be referred to Chlorospingus; it has a much stouter and thicker bill and large Fringilline feet. I am not sure that its correct position is not with the Ground-Finches (Pipilo &c.), but for the present I propose to leave it among the Tanagers under a separate generic name." (P. Sclater 1885).
