1842.] Malayan species of Cuculidoe. 917 



tern parts of Java are generally of this description. In the extensive 

 central plains intervening between abrupt, conical, and elevated 

 mountains, and which are generally in a high state of culture and 

 covered with flourishing towns and villages, I have rarely observed it. 

 This bird retires into the deepest coverts, and having a dark plumage, 

 it is with difficulty surprised. Its peculiarities, both as to voice and 

 habits, have not, as far as known to me, been observed. Its habits 

 are very different from those of C. (Eudynamys) orientalis and the 

 C.flavus, both of which are very abundant in Java." The specimen 

 here described was brought from Singapore. 



Subgenus Chrysococcyx, Boie (1826), v. Lampromorpha, Vigors, 

 v. Chalcites, Swainson. (Metalline Cuckoos.) The members of 

 this group absolutely resemble the first or typical Cuckoos in struc- 

 ture, being merely characterized, in addition to their very small 

 size, by the resplendent metallic hues of their plumage. 



At least three inhabit the Malay countries, two of which are des- 

 cribed by Dr. Horsfield in Lin. Trans. XIII., 179, and one of them 

 more elaborately in his ' Zoological Researches in Java' ; besides which 

 the next appears to be not uncommon in the Malay peninsula, if 

 not also in the Tenasserim provinces.

 286, — the female; C. metallicus, Vigors, Ibid. XV. 303, — the young, 

 as satisfactorily shewn by specimens in transitional plumage. (Banded 

 Emerald Cuckoo.) What are evidently the male, female, and 

 young, of a species which appears to be referrable to the foregoing, are 

 clearly identical with one another, the intervention of the female 

 livery assisting to demonstrate the necessity of bringing the above 

 synonyms together. Length of a splendid male fully seven inches, of 

 wing four inches and a quarter, and tail three inches, its outermost 

 feathers half an inch shorter; of bill to forehead (through the feathers) 

 five-eighths of an inch, and tarse half an inch. Bill, in the dry specimen, 

 translucent pale straw-yellow, both mandibles tipped with dusky. 

 All the upper-parts, with the breast, brilliant dark emerald-green, the 

 feathers silky in texture, and having a rich and slightly aureous 

 silken gloss; belly, sides, and under tail-coverts, with the inside of 

 the wings anteriorly, white, transversely barred with shining green ; 

 tail like the back, a pair of unmoulted old feathers, next to the uropy-
