 in den beiden ersten Theilen meiner «Beiträge» besprochenen 

 Arten nicht unwesentlichen Antheil an den früher erzielten Resul-

 gehabt. Es würde jedoch zu weit führen, wenn ich diese schon 

 früher hervorgehobenen Ergebnisse an dieser Stelle nochmals dar-

ON BRACHYRAMPHUS PERDIX (PALL.) 

 AND ITS NEAREST ALLIES. 



(Plate VII). 



By Leonhard Stejneger. 



A specimen of «Murrelet» from Kamtschatka, just received, 

 shows that we have to remove Pallas's Cepphus perdix from the list 

 ol Synonyms. It comes nearest to Brachyramphus marmoratus (Gm.), 

 having uniform dusky tail-feathers and secondaries, as well as an 

 elongated slender bill, but the latter is somewhat longer, and the 

 coloration of the Upper parts in summer, is much more like that 

 of B. brevirostris (Vig.), the species which is usually called B. kitt- 

 lit\u\ It belongs to that group of the genus, which has the tarsus 

 shorterthan themiddletoe, and the under wing-coverts dusky gray in 

 the adults. The three species belonging to this group may be distin- 

 guished thus : 



a ) Exposed culmen not more than two thirds the length of 

 inner toe without claw ; outer secondaries broadly tipped 

 with white ; outer tail-feathers more or less white. 

 1. B. brevirostris. 

 a 1 ) Exposed culmen about equal to the inner toe without claw ; 

 all the secondaries and tail-feathers uniform dusky.
