[Received January 24, 1871.] 



Euplocamus andersoni, sp. now 



E. facie rubra : crista et corpore subtus indigoticis : dorso toto, 

 alis et cauda yrisescenti-albidis, Mis lonyitudinaliter, hac 

 transverse fasciatis : remiyibus et rectricibus externe latins 

 niyro trans fasciatis : rostro pal/ide cameo. 



Entire upper parts greyish white, each feather having three or 

 more black irregular lines running parallel to the edge, and meeting 

 towards the end. Secondaries with broad transverse black lines. 

 Top of head and lengthened crest, together with the entire under- 

 pays, deep rich blue. Tail long ; middle feathers greyish white, 

 thickly covered with transverse black lines ; rest of tail-feathers 

 similar, but the black lines broader. Bill pale green. Legs and feet 

 greyish. Bare skin of face crimson. Size a little larger than E. 

 lineatus. 



I have taken the description of this apparently new form of Eu- 

 plocamus from a native drawing of the bird copied from life, and 

 kindly placed in my hands by Dr. Anderson, the Curator of the 

 Indian Maseum of Calcutta. The specimen was obtained in Burmah 

 on the Chinese frontier, and is apparently an intermediate form 

 between E. lineatus and E. nycthemerus. The E. andersoni differs 

 from the E. lineatus in the markings of the upper parts, which are 

 longitudinal, the feathers being entirely free from transverse markings 

 or mottling ; and may be distinguished from E. nycthemerus by the 

 closely striated middle tail-feathers, the differently marked outer 

 tail-feathers, the pale colour of the legs and feet, and the compara- 

 tively small size. There are no white central streaks to be seen upon 

 the flank -feathers as in E. lineatus ; but this is not of specific 

 importance, as that character varies considerably among different 

 individuals. The new bird can hardly be deemed a hybrid between 

 the two species with which it has been compared, as their habitats do 

 not join, and there is no appreciable way by which they might get
