'■'■Adidt (type. No. 1583, Science College Museum, Tokyo, Japan ; 

 Prov. Mutsu, Japan). In coloration exactly like ffi". hrevipes 

 (Peale), except that the greater wing-coverts are lighter slate-grey, 

 distinctly, though narrowly, margined with white ; the feathers of 

 back with paler (white) and more distinct terminal margins, the 

 dusky border to underside of wing narrower and interrupted along 

 outer margin, and inner webs of primaries with a conspicuous 

 lengthened wedge of pure white. Proportions, however, very dif- 

 ferent from those of (E. hrevipes, the bill being much longer and 

 slenderer, and tail less graduated. Length (skin) about 9-75 inches, 

 wing (primaries moulting), tail 3"80, its graduation 0*75, culmen 

 0*95, depth of biU through middle 0"25, tarsus 1'25, middle toe with 

 claw 1-40. 



" Another specimen from the same locality (No. 1.584, Science 

 College Museum, Tokyo) is quite identical in coloration, its 

 measurements (except length of wing, the primaries being partly 

 moulted) being as follows : — Total length (skin) about 9'30, 

 tail 4*00, its graduation 0-90, culmen 0-98, depth of biU through 

 middle 0-25, tarsus 1"10, middle toe with claw 1"30." {Ridgway, 

 in Hit.)

Adult male. Similar to (E. cooH, but purer grey and without the 

 dark patch on the rump ; median and greater wing-coverts greyer, 

 with whiter edges ; primary under wing-coverts white, the edge of 

 the wiog, especially over the ulna, more broadly black; secondary
