● "*Holoquiscalus niger crassirostris (Swainson).¹   ...   ¹ Ridgway and Peters have adopted for this form the subspecific name jamaicensis of Daudin (Traité Elém. Compl. Orn., 2, p. 317, 1800), a procedure that appears to me hardly justifiable.  Daudin based his name by no means  exclusively on Brown's "Merops niger, iride sub-argentea" from Jamaica, but this is merely one of the references which he believed to pertain to one and the same bird, for which "plusieurs îles des Antilles, la Jamaïque et le Labrador" are given as habitat. The only specimens actually seen by Daudin, upon which the description of his Sturnus jamaicensis was probably based, are those sent to the Paris Museum by Maugé from Porto Rico and "St. Thomas" [= H. n. brachypterus].  I do not advocate, however, transferring Daudin's name to the Porto Rico form, and would rather consider it an unidentifiable mixtum compositum."
