A JR^E VISION OF THE GEISUS GENN.^US. 677 



at this latter place may prove to be abnormal. It appears to be 

 fon ad up to and sometimes above 5,000 feet, but its usual habitat 

 would appear to be somewhere between 2,500 and 4,000 feet. 



There is a specimen in the British Museum received from the 

 Hon. the East India Company's Collection, labelled "Bhutan Hima- 

 layas" c? No. 44.9;4.3. This of course is an incorrectly given 

 locality. 



The following birds also appear to be wrongly labelled : —

Description : adult male. — Intermediate between Gennoius horsfiddi 

 cuvieri and Gennceus lineatus lineatus, nearer perhaps to the latter 

 than the former. The markings on the upper plumage are very 

 fine and give the same unicolored appearance as is seen in true 

 lineatus at a distance, but when seen close by, the vermiculations are 

 found to be bolder and more defined. There is still sufficient 

 indication of the barring on the rump to make this part of the upper 

 plumage contrast with the rest, and in one specimen from Thazi- 

 Taungyi the barring is quite strongly developed. The flanks and 

 sides of the breast and lower neck have broad white shaft lines, and 

 the central rectrices are broadly white on the outer web. 



The female. — Difiers from that of horsfieldi and cuvieri in having the 

 whole tail above and below irregularly barred with pale dull rufous. 

 Of the three specimens in the B. M. Coll., two have the rectrices a 

 dull pale chestnut brown, and the third has them a chestnut rufous . 

 In each case the central rectrices are somewhat paler and more 

 rufous than the rest, but not sufficiently so to cause a contrast as 

 occurs in horsfieldi in similar cases. The type female has no pale 

 striae on the upper parts, but is redder than most female horsfieldi, 

 the others have these tiny central strias to the feathers, but are 

 otherwise more like normal females of that bird. All have pale 

 central striae to the feathers of the neck, breast and upper flanks, 

 similar to, though less pronounced than in the females of lineatus.
