Accipiter pileatus (De Wied) PI. col. 205, This is not correct, as may readily 

 be ascerlained by reference to numerous specimens of loth those species in 

 the collection of this Academy. 



In fact but a small degree of resemblance exists between any age or se.x of 

 the two species, so far as I have seen. The A. Cuoperi, is much the larger, nor 

 have I ever seen a specimen of this species assuming plumage at all approaching 

 that represented in Pi. col. 205. 



8. Circus cijaneus. (Linn.) 

 Young birds from near Jalapa. 



9. Ephialles atricapilla, (Natt.) PI. col. 145. 



10. Syrnium, ? 



A species to which I am not at present prepared to attach a specific name. 

 I have reason to suppose that it is one of the species which Mr. Gray has named 

 in his List of the Rapacious birds in the British Museum, of which no description 

 has come under my notice, if published. 



11. ISyctidromus Derbyanus, Gould. Icon. Av. ii. pi. 2. 



A young bird from the neighbourhood of Jalapa, where it lives all the year. 



12. Mumotus braslliensis, (Lalh.) 



Near Jalapa, found in thickets, iris red 



In the specimen brought by Mr. Pease, and also in two others from Mexico 

 in the Rivoli collection, the crown of the head is much lighter coloured than 

 is usual in South American specimens. 



13. Trogon mexicanus, Swainson, Gould. Mon. PI. 2. 



14. Trogon exalapensis, Du Bus, Esquisses Orn. I. pi. 2. 

 Two males, from the neighbourhood of Jalapa. 



15. Trogon amhiguus, 1. Gould. Mon. pi. 4. 



A young bird, sufficiently ambiguous at least to be referred to this species. Of 

 these three species, Mr. I'ease has the following note: "Live on the tierra icmplada 

 the greater part of the year, in the thickets bordering small streams, very shy, 

 but when alarmed flying only a short distance and endeavouring to conceal 

 themselves. The plumage appears to be very slightly attached to the skin, and if 

 you are so unfortunate as to wound a specimen, it is almost entirely lost in the 

 struggles of the bird." 



16. Alcedo americana, Gm. pi. Enl. 591. 

 Neighbourhood of Jalapa, all the year, 



17. Alcedo vestila, Lesson. Traite, I. p. 242." 



I give this name on the faith of labels attached to specimens in the Rivoli 

 collection, M. Lesson's description being too short to enable me to identify the 

 species satisfactorily. 



IS. Cyanocorax ornatus, (hesson.\ Rev. Zool. 1839, p. 41. 

 On the sides of the mountains all the year. 



19. Cyanocorax peruvlanus, (Gm.) Le Vaill. Ois. de Par. 46. 



The specimen brought by Mr. Pease, agrees exactly with the description of 

 Garrulus luxuosis, Lesson, Rev. Zool. 1839, p. 100, which is also Mexican. 

 I can find no difference, however, between the present specimen and the young 

 C. pernvianus, from South America. 



Mr. Pease notes : "This species lives on the sides of the volcanoes all the
