Fam. TuEDiD^. 



1. Turdus ustulatus Nutt. 



" " Proc. Bost. Soc. of N. H., xiv., p. 276. 



Tres Marias, Jan., 1865, Grayson. 



"I found this bird quite abundant on the Tres Marias Islands when I was there in the months of January, 

 February, and April. It was very shy and timid ; this fact alone led me to believe that it was a winter visitant 

 to this locality — a stranger. 



" Since I made its discovery in this remote locality, I find that Prof. Baird, in his description of the above- 

 named species (Rev. of Am. Birds, p. 18), states as follows : ' This species hitherto has not been noted as 

 found outside the limits of Washington Territory and northern Oregon, nor as far east as the Rocky Moun- 

 tains — the most eastern point being Chiloweyuck, (July 3, 1859, Dr. Kennerly), where it was found breeding 

 very abundantly.' 



" The important fact that it selects the Tres Marias Islands for its winter migrations, and is nowhere found 

 on the main-land in this vicinity, is of extraordinary interest." 



2. Turdus grayi Bp. 



" " Proc. Bost. Soc. of N. H., xiy, p. 276. 



Tepic, Tres Marias, Grayson. 



" At times during the winter months it is abundant in the Tres Marias. Frequently met with In the tierras 

 calientes of the main-land; I found it breeding near Tepic in the month of May. It is gregarious and semi- 

 migratorius. There are many points of similitude in this species and our T. migratorius, especially in its 

 habits, but the colors in the plumage are very distinct. It is a Mexican species and found in various localities 

 of this region." 



3. Turdus fiavirostris Sw. 



" " Proc. Bost. Soc. of N. H., xiv, p. 276. 



Mazatlan, Tres Marias, Grayson ; Plains of Colima, Xantus. 



"Is also abundant on the Marias as well as the main-land, and may be found in either locality throughout 

 the year. It is an inhabitant of the woods, gregarious and semi-migratorius ; passing from one part of the 

 country to another in quest of the different kinds of berries, which are its chief subsistence. The resemblance 

 between this and our common robin of the Atlantic States is quite appreciable." 



This species appears to be peculiar to western Mexico. It seems to be rare in European 

 collections, as Messrs. Sclater and Salvin state (P. Z. S., 1870, p. 550) that a specimen 

 from Mexico submitted to them by Mr. Boucard, was the first to come under their notice 

 in collections from that country. Numerous specimens are in Col. Grayson's collection 

 from the Tres Marias and Mazatlan. It abounds also in the vicinity of Tehuantepec, 

 whence Prof. Sumichrast has sent many very fine examples. 



4. Melanotis ccerulescens (Sw.). 



" " Proc. Bost. Soc. of N. H., xiv., p. 275. 



Mazatlan, Tepic, Tres Marias, Grayson ; Plains of Colima, Xantus. 



" Very abundant in the Islands of the Marias, and one of the most interesting songsters of that locality 

 where it is very docile, inhabiting the thick woods. Upon the main-land, in the vicinity of Mazatlan, it is 

 not so common, and is very shy."
