A^ pennata. This bird, in India, has always a rudimentary 

 crest. 1 obtained it near Moulmein. But I do not approve of 

 classing the former in Hieraetus. 



P. 91. For Francolinus perlatus read, "the Perdix oculea of 

 Hardwicke's illustrations." The common Pegu Francolin {Fr. 

 phayrii, nobis) I consider to be distinct from F. perlatus of China 

 (and now of Mauritius) . It is less stout, and the male has more 

 developed spurs ; but the two are very similar in plumage. 



P. 92. Falco sacer proves to be not uncommon in the extreme 

 N.W. of India, in the Sulimani range, &c. This, with F. cherrug, 

 F. lanarius, &c., are emphatically desert Falcons, as the Hiero- 

 falcones are Arctic, and the Peregrine group might be termed 

 cliff Falcons. To these desert Falcons Gould^s Hieracidece (the 

 adult and young of apparently the same species figured as dif- 

 ferent) approximate nearly; and surely, also, those antipodal 

 species that have been ranged in Hierofalco. 



P. 93. I now think that Oriolus indicus and 0. chinensis are 

 the same, but I want better Chinese specimens to judge from. 1 

 obtained both O. indicus and 0. tenuirostris at Moulmein, but 

 the female only of the latter, which is very similar to the female 

 of 0. indicus, excepting in the head and the form of the bill. 

 The female of O. tenuirostris is still a desideratum. 



The following notes ai'c extracted from Mr. Blyth's more recent 

 letters : — 



" Two distinct races of Cuckoos have been confounded under 

 the name Cuculus striatus, Drapiez, but were distinguished long 

 ago in the ' Madras Journal ' by Lord Arthur Hay, — a larger aud 

 a smaller species. The former is C. striatus, Drapiez, from Java ; 

 and we have it, identically the same, from Malacca and from 

 Mussoree. It is C. affinis, A. Hay. The latter is C. tnicropterus, 

 Gould. This I have never seen from the Malayan region, but 

 it is common in Burmah during the rains. I obtained there 

 also, in the cold season (at Moulmein), the young of Cuculus 

 canorus ; and C. himalayanus in Upper Martaban, 



"Gould gives Strix flammea in his list of birds from near 

 Bankok (P.Z.S. 1859, p. 151). He must mean S.javanica, which
