504 ON THE BIKDS OF HAINAN. [May 8, 



is most nearly allied to G. nyciliemerm, but, as may be seen from 

 tbe accompanying drawing (Plate XXXIY.), differs conspicuously 

 in many important particulars. 



Crown black with a slight blue gloss ; nuchal crest rather 

 long (2-5 inches) and similarly coloured, the longer feathers being 

 decomposed. 



Adult male. Nape and upper mantle pure white ; each feather 

 of the lower mantle, back, rump, and shorter upper tail-coverts 

 with one black submarginal band on each web, forming an arrow- 

 head black marking, which gradually increases in width towards 

 the tail, most of the feathers being also narrowly fringed with 

 black. "Wing-coverts similar, but with the black markings much 

 coarser. Longer upper tail-coverts and secondaries very boldly 

 marked with successive black arrow-heads. Primary-quills black, 

 with wide oblique white markings. Middle tail-feathers pure 

 white ; second and third pairs white, with wide (about 0-5 inch) 

 oblique black bands on the outer web ; the latter pair with some 

 irregular black marking on the inner web also ; remaining pairs 

 white, with wide oblique black bands on both webs forming an 

 irregular arrow-head pattern. Underparts black, some of the 

 feathers of the sides with narrow white middles. Iris brownish 

 yellow ; naked wattle and skin on sides of face scarlet ; bill greenish 

 white ; legs coral-red. 



Total length 35 inches ; wing 9*4 ; tail 20 ; tarsus 3*15. 



Adult female. Most nearly resembles the female of G. andersoni, 

 but is much darker. The feathers of the neck and mantle mostly 

 black with wide white shaft-streaks ; the uuderparts, including the 

 under tail-coverts, similar, but with wider white middles. Outer 

 tad-feathers uniform dark chestnut, with indistinct vermiculations 

 of black. Iris light brown ; upper mandible greenish brown, lower 

 dull green ; naked skin on face red ; legs and feet bright scarlet. 



Total length 21-5 inches ; wing 8-1 ; tail 8-8 ; tarsus 2-9. 



Mr. Whitehead secured three adult males and one female of 

 this splendid Silver Pheasant.
