p. 303), since figured (Exotic Orn., Part II., Jan. 1S67), but the 

 coloring below is very different. Of this last species I have a 

 female from Bogota, which agrees quite well with the descrip- 

 tion of the specimen, mentioned by Scl. and Salv. (Exot. Orn.) 

 as beinsr in the British Museum. The feathers of the sides and 

 thighs are of a clear rufous; the breast is paler and duller, on 

 which there are whitish transverse markings. The under tail 

 coverts are nearly white. 



It measures, length 12 in. ; wing 8; tail 6| ; tarsi 21. 



Notes on rare or little known Species. 



1. Icterus anratus, Bonap. 



Since the completion of my ''List of a Collection of Birds 

 from Northern Yucatan," Prof. Baird sent me two specimens of 

 an Icterus belonging to that collection, which had been overlook- 

 ed. They were also submitted to Mr. Cassin after he had finished 

 his monograph of the Icterid^e. He considered the species to 

 be undescribed; but I am of the opinion that, had he carefully 

 examined it, at the time of investigating for his Monograph, his 

 conclusion would have been different, and its true position would 

 have been assigned it. It is without question, I think, Icterus 

 auraiuSf Jhnap., Consp. Av. 1, p. 435, as it agrees with the de- 

 scription of that species, and for which the same locality is given, 

 viz., Yucatan. 



The bird to which Mr. Cassin has applied this name, is a spe- 

 cies that has generally been confounded with I. xanthomas, and 

 does not answer Bonaparte's description in Consp. Av., as I will 

 presently point out. 



I think Mr. Cassin was misled, in part, by taking it for granted 

 that the specimen which Bonap. states (Compt. Rend., 1853, p. 

 835) is in the Brussels Museum, when speaking of the species 

 confounded with xanthornus, is one and the same as /. aura tits of 

 his Consp. A v., a specimen of which he also says is in the Brus- 

 sels Museum. I infer that he means two distinct birds, as he
