is of a smoky brownish gray. It will be seen from the table of meas- 

 urements that tbe bill is as big as that of a full grown Haliceetus leuco- 

 cephalus, notwithstanding the fact that the knob at ihe tip of the upper 

 mandible has not yet disappeared. The lores are naked, with only a 

 few scant bristles. 



During the first days of June, 1883, after I had left Petropaulski, 

 one of the natives secured for me the contents of a nest and one of the 

 parents, No. 92735. In the nest were two eggs containing nearly 

 hatched young, and as the hunter accidentally broke one of the eggs, 

 he only sent me the foetus in alcohol. ■ The down of the latter (No. 

 92990) is pure silky white all over.

The Osprey, lik6 the other raptores feeding on salmon, is very 

 abundant in Kamtschatka. To the islands, however, this species only 

 comes as an occasional visitor. A specimen was recorded, as seen 

 on Bering Island, May 24, 1883, during my absence in Petropaulski, 

 whiere, as will be seen from the list of specimens collected, on the same 

 day I secured two specimens, it being then very numerous at the few 

 open places on the rivers and along the coast. 



It will be seen from the measurements given below that the eastern 

 birds are not smaller than European examples. Two Japanese speci- 

 mens in the collection are still larger, so that»the existence of a smaller 

 race, " on'ejitoiis," in Japan seems to be out of the question, as already 

 remarked by Captain Blakiston. 



With the Japanese specimens those collected by me agree very well 

 as to color, the spots on the breast being even darker and larger, if 

 anything, in the latter, and the shafts of the rectrices are brown at the 

 lower end. They are consequently referable to the Old World typical
