America is remarkable for differing widely from the North 

 American forms, while it much resembles the form found in 

 Argentina and Patagonia (C. cinnamominus cinnamominus) . 

 BuTEO soLiTARius Peale. From Hawaii. Although not 

 an American Hawk, this species is so little known that the 

 skin shown is of interest, especially as it closely resembles 

 the type in the Philadelphia Academy Museum. 



Dr. E. Hartert communicated the following descriptions 

 of new subspecies : — 



Alauda arvensis herberti, subsp. nov. 



This is the Skylark breeding round Bangkok in Siam. It 

 looks very much like A. a. wattersi, and belongs, like the 

 latter, to the group of subspecies formerly regarded as 

 another species, A. gulgula, but differs from A. a. wattersi of 

 South and Middle Formosa in being larger and having finer 

 striations on the chest. Wings, 4 ^ , 88-91 ; ? , 85*5 mm. 



Hah. Near Bangkok (Williamson). 



Type^ in the Tring Museum. ^ ad. Bangkok, 31. iii. 1915. 

 W. J. F. Williamson coll. Named after E. G. Herbert, to 

 whom we owe interesting material from Siam. This is the 

 bird called A. gulgula sola in Gryldenstolpe's list of the birds 

 of Siam, but A. a. sala is larger, heavier streaked on the 

 chest, has heavier bill, and inhabits North Formosa, not 

 Siam. 



Eremomela flaviventris tardinata, subsp. nor. 



? ad. Upperside olive-brownish, on lores and sides o£ 

 crown a whitish-grey superciliary line, a dark olive-brownish 

 one on lores and behind the eye ; lower portion of sides of 

 head, throat, crop, breast dirty white, creamy tingo on chest ; 

 lower abdomen, vent, and sides of vent lemon-yellow, thighs 

 whitish, under tail-coverts very pale yellow. Under wing- 

 coverts and axillaries brownish, almost like back. Edges of 

 primaries and inner secondaries, inner edges and tips of 

 rectrices whitish. Wing 52*5, tail 23 mm. (Bill in skin
