ORNITHOLOGICAL EXPLORATIONS. 331 



33.1. Stercorarius pomarinus. — This species is given in the "Liste" 

 (p. 3, No. Ill) under the name of Lestris pomarina, as occurring iu 

 Kamtschatka and Bering Island. If the information is reliable, this 

 constitutes a veritable addition to the number of Kamtschatkan species. 



Diomedea nigripes "Audub." is now given as the only albatros from 

 Kamtschatka and Bering Island. I need hardly add that the identifi- 

 cation is entirely erroneous, but lb proves that I was completely justi* 

 fied in the suspicion expressed by me above under JSTo. 35 (p. 310). 



78.1. Chaulelasmus streperus. — This species is given as obtained on 

 Bering Island. It has probably been taken during the spring migra- 

 tion, 1883, while I was in Petropaulski. 



Merganser merganser. — The authors identify the Kamtschatkan and 

 Bering Island birds as " Mergus merganser americanus,^^ saying, however, 

 that " Le male adulte ne se distingue de celui de la forme europ6eune 

 que par la couleur de I'abdomen, ros^e au lieu de saumon, et par le vert 

 brillant du sommet de la tete et du cou, remplac^ par le violet." Com- 

 pared with what has been said above of the two species (p. 176 seqv.) 

 it is plain that Messrs. Dybowski and Taczanowski are entirely mistaken 

 in their identification. 



Brachyramphus Jcittlitzii. — The " BrachyrampMts sp. ? " of the former 

 lists has now been changed to ^^ Synthliborhynclms sp. ?" {Synihliborhyn- 

 elms sic!). What is it, after all, if it is not B. JdttUtzii f 



Cerorhinca monocerata has been dropped altogether, without good 

 reason, as it seems. 



The eflect of this "Liste" upon the foregoing synopsis is as follows: 



We have to eliminate Nos. 35 and 122, and to add Stercorarius poma- 

 rinus and Chaulelasmus streperus. The number of well authenticated 

 birds is, therefore, still 186, as in my synopsis.
