Show 564 DR. O. FINSCH ON THE BIRDS OF TRINIDAD. [Julie 23, of the secondaries rufous brown, with some indistinct dark bars; two middle tail-feathers dark brown with numerous (nineteen) blackish bars, remainder of the tail-feathers brownish black, with a broad (5"') white cross band before the narrow dark end; bill black horn-colour, pale greyish at the base of the lower mandible; legs dark greyish brown, claws paler.

Dr. Cabanis bas pointed out the characters of this apparently rare species, which is not mentioned in the work of Dr. Leotaud, in a very brief manner; a minute description therefore was necessary. Unfortunately I possess no specimen of H. griseus, Sw., which seems to be sufficiently distinct, not only in being considerably larger (as the measurements noticed by Von Pelzeln prove), but also in the coloration. Dr. Sclater notices, besides II. griseus, also a II. minor from Trinidad; but this latter " being so similar to //. griseus in every respect, except in size, I question whether it may not be a variety of age or sex of that species" (P. Z. S. 1856, p. 97). H. minor, as thus described, may be very probably only a smaller-sized specimen of the true H. griseus. Fam. LUSCINIADJE. MNIOTILTIN.E. 36. SYLVICOLA .ESTIVA (Gmel.).

Might not this be S. petechia, L., which Dr. Sclater (Cat. p. 32) considers to be different from S. eestiva 1 But, as Dr. Leotaud states, S. eestiva arrives only as a winter visitor in the island of Trinidad.
