From his discussion of the claims of Lestris richardsoni to be considered a good species, 

 the author passes to review the entire subfamily, recognizing the following genera and spe- 

 cies :— 



I. BuPHAGUS, Moehr. 1, B. skua (Briinn.). 2, JB. antarcticus (Less.). 



n. Stercoeaeius, Briss. S, S. pomarinus (Temm.) {lege pomatorhinus) . 4, S. parasiticus] 

 Briinn. 5, /S. richardsoni (Sw.). S.hardyi(Bp.). 7, S.spinicaudalBp.). 8, (S. 6«</om (Bole). | 



The nomenclature of this paper is eccentric, the author having apparently imbibed somoj 

 untenable views of G. K. Gray's on this subject. S. richardsoni has not proved valid. The 1 

 four unquestionable Jagers of the Northern Hemisphere are carefully distinguished and 

 adequately described, with copious synonymy. See same author at 1874, Birds of the North- 

 west.
