iESALON REGULUS INSIGNIS Clark, new subspecies. 



Type.—Cat. No. lf4580U.S.N.M.; male, I^^usan, Korea; P. L. Jouy, 

 collector. 



A merlin from Korea which I have before me differs so much from 

 European examples and from specimens from Japan that it seems 

 probable it represents a new race. Unfortunately, the bird is in 

 juvenile plumage with a few feathers of the adult in the l)ack and one 

 in the tail. It resembles .JE. r. regulus from Europe in the same 

 plumage, but is much lighter throughout, with the brown streakings 

 below lighter and much narrower. The gray feathers which are just 

 appearing indicate that in the adult livery this bird will be much 

 lighter than its European representative. 



CERCHNEIS PERPALLIDA Clark, new species. 



Tijpe.^Cfit. No. 114579 U.S.N.M. ; male, Fusan, Korea; P. L. Jouy, 

 collector. 



This species resembles C. tinnunculus from Europe, but is paler 

 throughout, except the thighs, which are in sharp contrast to the 

 creamy white under parts. The gray on the head is paler, and is 

 continued down onto the shoulders and interscapulary region, grad- 

 ually merging into the rufous of the back; this color also occupies 

 the sides of the head and neck, extending down onto the sides of the 

 breast. 



BUBO TENUIPES Clark, new species. 



Type. — Cat. No. 114()18 U.vS.N.M.; male, Fusan, Korea; P. L. Jouy, 

 collector. 



Similar to B. huho from Norway, but smaller, the feet and claws 

 very much smaller and weaker, and the tarsus much more slender. 

 The coloration above resembles that of B. huho, but the ground color 

 is darker rufous, with the dark mottlings more extensive, except on the 

 nape, and the light areas on the primaries larger. Below this spe- 

 cies is somewhat darker rufous than B. huho: the feet are light 

 rufous, obscurely, but thickly, barred with brown. The feathering 

 of the toes is as in B. hengalensis. 



The average measurements of three males fi^om Korea are, wing, 

 439 mm.; tail, 245 mm.; tarsus, SO mm.; middle toe, 46 mm.; claw 

 of middle toe, 31 mm.
