Long. tot. 5i uuc. ; alw, 3~ ; caudaJ, 2 ; tat·si, 1}; rostri, ~ ; alt. rostri, i. Upper part of the body deep brown, with each feather margined with cinereous olive; the throat and breast cinereous olive, with the middle of each feather darker ; the abdomen, sides, and under tail coverts cinereous tinged with straw colour. Habitat, Galapagos Archipelago, (Charles Island~) I am nearly certain that this species is not found in James Island. I believe it came from Charles Island, and probably there replaces the C. psittacuius of James Island. I obtained three specimens, one male, and two females; from the analogy of so many species in this group, I do not doubt the old male would be black. SuB-GENUs.-CACTORNIS. Gould CACTORNIS dijfert a genere GEOSPIZA 1·ostro elongato, acuto, compresso, longitudine altitudinem excellente; mandibula: superioris mm-gine vix indentato; nm·ibus basalibus et vix tectis ; tarsis brevioribus, unguibus majoribus et plus cuTvatis. Cactornis scandens is the typical species. 1. CACTORNIS SCANDENS. Gould. PLATE XLII. C. intense fuliginosa, crisso albo; rost1·o et pedibus nigrescenti-brunneis.

Deep sooty black, with the under tail-coverts white ; the bill and feet blackishbrown. Female: Upper surface of the body, throat and breast intensely brown, with the margins of each feather paler ; the abdomen and the under tail coverts cinereous, tinged with straw-colour; the bill pale fuscous, and the feet blackish fuscous. Habitat, Galapagos Archipelago, (James' Island.) The species of this sub-genus alone can be distinguished in habits from the several foregoing ones belonging to Geospiza and Camarhynchus.
