Gray). Lesson, in his description of C. sericeus, quotes the 

 number of the figure which represents A. zenuhia. 



A young male from Mysol in my collection is not to be distin- 

 guished from the specimen, described further on, of C. auri- 

 ceps. But it has only put on two metallic shoulder-coverts, and 

 two of the neck-stripe plumes, and that on one side only. One 

 of the dorsal feathers is tipped with metallic-green. On the 

 habits of this species, consult Miiller (/. c). 



34. Chalcostetha ASPASioiDEs, (G. R. Gray), P. Z. S. 1860, 

 p. 349, " Amboyna.'' 



A species doubtfully separable from C. aspasia. 



35. Chalcostetha porphyrol^ma, (Wallace), P. Z. S.1865, 

 p. 479, " Macassar.'' 



The violet-purple throat at once distinguishes this species from 

 C. aspasia. 



36. Chalcostetha proserpina, (Wallace), P. Z. S. 1863, 

 p. 32, c? 2 , " Bourn." 



A larger bird than C. aspasia, the middle and greater wing- 

 coverts not metallic, but otherwise exactly like it. A Bourn 

 example marked a female, in my collection, presents no features 

 (its larger dimensions excepted) whereby it can be distinguished 

 from the young male of C. aspasia already noticed, beyond 

 that the tail is dull brown, and not black, and w^ants all traces 

 of a silky or metallic gloss. This, as far as my investigations 

 permit me to state an opinion, is a characteristic of the female 

 in some, if not in all, of the Eastern Sun- birds. 



37. Chalcostetha auriceps, (G, B. Gray), P. Z. S. 1860, 

 p. 348, '' Batchian, Teruate." 



Hab. Sula Islands, Batchian, Gilolo (Wallace). 



This species is to be readily distinguished from the four last 

 by the top of the head being bright golden green ; otherwise 

 it is closely allied. An example of a female (so marked by 

 Mr. Wallace) in my collection, from Ternate, is above cinereous- 

 brown, washed with olive-green on the dorsal region. Occi- 

 pital feathers with pale cinereous edgings. Cheeks, chin, 

 throat, and upper part of breast greyish-white; remainder of
