On looking through this list it becomes apparent that the ornithology of this part of Honduras, so far at least as is shown by Mr. Whitely's collection, differs in hardly any respect from that of the lowlands of Vera Paz, which has been already thoroughly explored. Out of these 135 species there are only three (Dendrornis nana, Coccyzus minor, and Picumnus olivaceus) that have not been observed in the above-named department of the adjoining Republic of Guatemala. Of these three exceptions, Coccyzus minor is of wide distribution and may likewise occur in Guatemala ; but the other two are southern species which appear here at the most northern limit of their range. We subjoin a few remarks upon such of the above-mentioned species as require notice. 1. TURDUS TRISTIS, SW. ; Scl. et Salv. Ex. Orn. p. 145. Out of three skins in Mr. Whitely's collection one belongs to the ashy-backed variety (T. leucauchen, Sclater); tbe other two are intermediate between this and the Mexican form T. assimilis, Cab. This confirms us in our opinion (expressed Ex. Orn. p. 145), that the two species may be safely reunited under Swainson's older name. See also Mr. Salvin's remarks on this Thrush (P. Z. S. 1867, p. 132). 46. ICTERUS MESOMELAS, Wagler. Mr. Cassiu, in his study of the Icteridae (Pr Ac. Sc. Phil. 1867, p. 51), has separated the southern form of this bird as I. salvini, distinguishing it by the absence of the narrow external yellowish margin of some of the secondaries, and its larger size. We do not consider this proposed species to be well founded. In the present examples some possess the yellow margin, but others not. In a |
