I nave retained for the sake of uniformity the name Dorifera for the birds of the present genus, as it was employed by me in the previous volumes of this Monograph; but I admit that the more correct form of writing it would be Doryphora, as adopted by Messrs. Sclater and Salvin in their ‘ Nomenclator Avium Neotropicalium.’ In point of fact the name Doryphora will have to be suppressed among the Trochilide ; for it has already been employed by Illiger in entomology, and therefore the proper generic name to be used is Hemistephania of Reichenbach, as employed by Mr. Elliot. D. rectirostris comes from Ecuador, where it replaces the Colombian D. dudovicie, of which, in fact it is only a larger race with a somewhat longer bull. The following is a copy of the original description published by me in the ‘ Introduction : "— Bill and feet black; tarsi clothed with brown feathers; forehead brilliant glittering green ; crown and back of the neck reddish bronze, passing into dull green on the back; upper tail-coverts washed with blue; tail black, tipped with greyish brown, largely on the external feathers, slightly on the middle ones ; ander surface olive ; under tail-coverts grey ; wings purplish brown. I have not given a figure of this species, as there is not sufficient difference between it and D. ludovicie to be shown in a Plate DORIFERA EUPHROSIN A, Mus. & Verr. Mulsant’s Lance-bill.

I wave never seen the male of this species, which, however, appears to be known to Mr. Elliot, who regards ‘tas distinct from D. dudovicie on account of its small size and the peculiar bluish-green colour of the 5 sor “ 1 Jor = = frontal spot. I have in my collection a female collected by Mr. Edward Bartlett in the Peruvian Amazons, which I believe to be referable to D. euphrosine, the habitat of which is sapposed to be Ecuador.
