A CONTRIBUTION TO THE ORNITHOLOGY OF NEPAL. 313 



b. No black streak through the eye. 



3. Back always grey ; chiu and throat 

 black in summer only; small amount of 

 white on wing; smaller; wing, 3 3 to 



3-6 ; bill at front, 0-4 to 0-46 ... alba.* 



4. Back black in summer, often partly 

 black in winter ; chin and throat always 

 white ; considerable amount of white on 

 wing; larger; wing, 3*55 to 3'75 ; bill 



at front, 0*5 to 3*53 ... ... leucopsis. 



B. Black of head joined to black of breast, no white streak 

 down sides of neck. 



5. Back always grey ; less white on wing ; 

 smaller ; wing, 3*45 to 3*7 ; bill at 



front, 0"45 to 0"5 ... ... per sonata. 



6. Back black in summer, often partly black 

 in winter ; larger amount of white on 

 wing ; larger ; wing, 353 to 3*9 ; bill at 



front, 0-52 to 56 ... ... hodgsonu 



I have given the above table, not with the intention of in- 

 structing others, but rather to enable anv one to judge whether 

 I have correctly identified the species I obtained in Nepal. 



Motacilla amurensis, I only know from the description and 

 plate given by Mr. Seebohm {Ibis, 1878, pp. 345-346) ; it has 

 not been found in India, and is merely included because it pairs 

 so well with ocularis in the same way that leucopsis does with 

 alba, and hodgsoni with personata. The dimensions of amurensis 

 are not given ; nor is it stated whether it has the back grey in 

 winter ; but this is probable, I imagine. 



Winter examples, or young birds, of hodgsoni not showing 

 any black on the back can only be distinguished from personata 

 by the greater amount of white on the wing, by the conspicu- 

 ously larger bill, and generally by the larger size.

Three males, September, November, December. — Length, 7*8 

 to 8-1 ; expanse, IM to 11-75 ; wing, 3-73 to 3-75 ; tail, 3-85 

 to 4-2 ; tarsus, 0-9 to 0-95 ; bill from gape, 0-7 to 0*73 ; bill at 

 front, 0-5 to 0'53 ; closed wings short of tail, 2-3 to 2-4. 



Crown to nape black ; a broad black gorget ; chin, throat, 

 and an irregular band down sides of neck, pure white. 



Two females, September and December. — Length, 7*4 and 7'7; 

 expanse, 11 and 11'3; wing, 3*55 and 362; tail, 36 and 



* Including dukhunensis. Whether this should be retained as distinct is again a 

 raatter of opinion. — Ed.
