NESOSPINGUS
(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; Gundl. J. f. O. 1878, p. 168, 1882, p. 161(nest), et Añ. Soc. Esp. H. N. 1878, p. 190.   ...   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); "Nesospingus P. L. Sclater, 1885, Ibis, p. 273. Type, by monotypy, Chlorospingus speculiferus Lawrence." (Storer in Peters 1970, XIII, 254).
