J 843.] Mr. Blytk's Report for December Meeting, 1842. 943 



young appears to me to be a female in the plumage corresponding to 

 the hepaticus variety of C. canorus, which is so prevalent also in the 

 following species. 



Same page. For Cuculus Sonneratii, read C. poliocephalus, Latham, 

 vide p. 904. Both of these species (i. e. micropterus and poliocephalus J 

 have recently been obtained in southern India by Mr. Jerdon. 



Mr. Hodgson has also forwarded an apparently distinct species by 

 the appellation C. nisicolor, to which I have no hesitation in referring 

 the young specimen from Macao mentioned in a note to p. 240, ante. 

 It is closely allied to C. fugax, from which it is chiefly or wholly 

 distinguished by its much deeper colouring. Mr. Hodgson's example 

 would appear to be a remarkably small one, and is probably a female - r 

 but the difference of size between it and the young specimen from 

 Macao is not greater than occurs in the respective series of C. cano- 

 rus and C. micropterus now lying before me. Length about twelve 

 inches and a half, of wing six inches and five-eighths, and middle tail- 

 feathers five inches and three-quarters ; bill to gape an inch and three- 

 sixteenths. Colour of the upper-parts very dark pure ash- colour; 

 throat and cheeks the same, as in C. fugax: under-parts and tail 

 also as in the latter species ; but the flanks not barred (in the speci- 

 men) : throat below the chin contrasting with the dark ashy above and 

 laterally, and the central marking of the feathers of the throat deep 

 ash, like the rest of this colour, it being very dark on those of the fore- 

 neck. The Macao specimen is moulting its tail-feathers, but has the 

 wing seven inches and a half long, being probably a young male. Cap, 

 with the throat, ear-coverts, and sides of the neck, very dark ashy, 

 and several white feathers on the nape, as in some young examples of 

 C. fugax ; interscapularies dusky ash, very faintly rufous-barred, im- 

 parting a shade of that colour to the part ; scapularies, tertiaries, and 

 wing- coverts, successively more distinctly barred with bright rufous; 

 the fore-neck tinged and the plumage of the breast tipped with the 

 same; and the under-parts longitudinally streaked throughout with 

 dusky, shewing no trace of bars on the flanks : lower tail-coverts 

 dull white: bill and feet as in C. fugax. 



Since the Supplement to my Monograph on Cuckoos was published 

 (p. 240 ante J, Mr. Jerdon has favored me with copies of the descrip- 

 tions of Cuculidce in Lesson's Traile. The C. fugax is there des-
