may coalesce, I agree with Lord Tweeddale that they should not be 

 specifically united ; for I also have never seen a specimen of B, Jon- 

 gicawlatn that could be mistaken for B. pi/rrJinps or B. cineracea {cf. 

 Walden, B. Burm. p. 131); the grey in the tail of the latter is a 

 very good character, and easily recognizable. B. pyrrhops is nothing 

 more than a large race of B. cineracea. The measurements of ilr, 

 Blanford's Pegu skin are as foUows :— Total length 9-6 inches, cul- 

 men 0-9, wing .5-2, tail 5-5, tarsus 0-75.
