Some of the flat-billed tyrants have perhaps more analogy with 

 it, particularly in their habits, but it differs from them in the 

 appearance of its eggs and manner of incubation, as well as in many 

 other important particulars. It seems to me to form an entirely dis- 

 tinct family Todidae, which cannot be included in any other. 



Sylvieola. 



Panda. 

 Sylvieola americana Linn. 



Dendrmca. 

 Sylvieola coronata Linn. The southern migration of this bird is 

 more extensive than I had supposed. It was extremely abundant in 

 the interior of Jamaica in the winter of 1864-5. 

 Sylvieola diseolor Vieill. 



Sylvieola Adelaidce Baird. This new species was described by 

 Professor Baird in his review of North American Birds. 



Setophaga. 



Setophaga rut ie ilia Linn. 



Turdus. 



Mimoeiehla. 

 Turdus ardosiaceus Vieill. Abundant. 



Mimus. 



Mimus polyglottus. Yar. portorieensis. Several specimens. A 

 variation in white markings is the most indefinite of characters, and 

 I am inclined to think that this bird, with orpheus, dom.inieensis and cu- 

 banensis* etc., should be considered as varieties of polyglottus. I have 

 never seen a specimen of M. dominieensis, but as Mr. Sclater, comparino- 

 it with Orpheus says of it "forsan ab illo vix distinctus," I presume it 

 cannot be the same as the present bird, as this is easiJy distinguished 

 from Orpheus. In a typical polyglottus the whole of the outer tail 

 feather is white as is the 2d, with the exception of a portion of the 

 outer and a scarcely perceptible spot on the inner web ; but the white 

 occupies only a small portion of the 3d and the extreme tip of the 

 4th. In the present bird the white occupies the whole of the 1st and 

 2d outer tail feathers and the inner web and basal half of outer web 

 of 3d, the basal 5th of outer web and tip of 4th and a scarcely percep- 

 tible spot on the tip of 5th. In Orpheus the white occupies all the three 

 external tail feathers except a small spot on the outer web of the 3d 



*Tlie Cuban mocking-bird is easily distinguishable from, polyglottus.
