DESCRIBED BY MR. BROOKS. 97 



gave the length of the wing of his type as 2'75 ; he probably 

 intended 2'95, which is the length of the wing in one of his 

 types ; in the other it is 2*82 ; and in the Comillah speci- 

 men 2*9. 



In poliogenys the entire throat is paler than in rubeculoides ; 

 and in two specimens out of the three is sordid white without 

 any fulvous tinge ; in the third it has a slight tinge of fawn 

 color. The breast in all three specimens of poliogenys is a 

 dull, pale, rusty buff, very much paler and duller than the 

 corresponding parts in rubeculoides ; and whereas the greater 

 part of the abdomen in rubeculoides is, as a rule, pure white, 

 in poliogenys nearly the whole abdomen is coloured like the 

 breast, and scarcely at all paler than this. Then in rube- 

 culoides the sides of the head, including the cheeks and 

 ear-coverts, are much the same olive brown as the back, while 

 in poliogenys these parts are distinctly a grey or earthy brown, 

 or as some would call it ashy brown. As regards bills, legs, feet, 

 and wing formula there seem no marked differences, though 

 the third primary in poliogenys seems to run proportionally 

 somewhat shorter. 



My specimen, which is precisely like the types, was sexed a 

 5 by dissection, and I entertain no doubt myself that the 

 male will prove to be blue like rubeculoides ; possibly I may 

 have males in the museum, but I have not time now to go 

 fully into this group. I merely write this note now at 

 Mr. Brooks' request to indicate that, so far as I can judge, 

 Cyornis poliogenys is a good species. Mr. Brooks' two types 

 are, one from the Sikkim Terai, the other from the Bhootan 

 Doars. 



I have also examined Mr. Brooks' type specimens of 

 Calandrella tibetana, and find that I have many more specimens 

 of this in my museum. These are what I believe to be the 

 true Calandrella pispoletta ; at any rate they appear to me to 

 be the Calandrella pispoletta of E. F. v. Homeyer, J. Fur. O., 

 1873, p. 196. They have the long tail and the peculiar grey 

 colouring. Mr. Brooks' two types have a dull earthy brown 

 baud on the breast, but are not spotted there, but other 

 specimens in our museum from Thibet are strongly spotted 

 on this breast band. 



This, however, is not the Lark figured and described by 

 Dresser as pispoletta which is C. heinii of Homeyer. Of this 

 latter we have a good many specimens from the north-west 

 Punjab procured during the winter. This has a tail of 2'3 

 to 2*5, while in the grey pispoletta it is 2*7 to 2'85. 



Besides these two species, which occur within our limits (for 

 we have specimens of the grey pispoletta (tibelana, Brooks,) from
