Results of a Voyage to East Spitsbergen. 49 



Lestris pomarina. [Stercorarius pomatorhinus.'] 



King Charles Islands. A Pomatorhine Skua observed on 

 the 12th August (p. 250) . 



Barents Island. Observed on the night of August 5th-6th 

 with Larus tridactylus and Lestris parasitica, flying in 

 troops of from five to fifteen individuals^ from north to south 

 along the low-lying strips. As this species was not seen 

 until the end of July, it is inexplicable where the '' crowds " 

 seen in August came from (p. 250) . 



Olga Straits. Appeared at the end of July, and became 

 frequent at the beginning of August (p. 251). 



[Regarding the numbers seen by Dr. Walter, it is interest- 

 ing to recall the fact that the Rev. E. A. Eaton (' Zoologist/ 

 1874, p. 3812) also noted the abundance of this species in 

 August in Hinlopen Strait, and at Low Land on the north 

 coast. I am afraid it is not possible, in the present state 

 of our knowledge of the summer distribution of this species, 

 to form an opinion whence these crowds of migrants came. 

 Parry observed it in 82° N., while sledging northward of 

 Spitsbergen. — W. E. C] 



Lestris parasitica. [Stercorarius crejndatus.~\ ' 



Whale's Point Harbour. Richardson^s Skua was a very 

 abundant species and observed far inland (pp. 244 & 246). 



King Ludwig Islands. June 12th to 14th : many pairs 

 observed (p. 247). 



Ryk-Ys Islands. Only one of the dark form seen on the 

 North Island on July 30th (p. 249). 



Barents Island. Observed on the night of August 5th-6th, 

 along with Pomatorhine Skuas and Kittiwakes, moving 

 south (p. 250). 



Olga Straits. Everywhere, and increasing in numbers and 

 frequency to the beginning of August, both black- and white- 

 bellied forms being found (p. 251). 



Lestris BUFFONi. [Stercorarius parasiticus (L.).] 

 East Coast of Barents Island. The Long-tailed or BufEon's 

 Skua was twice seen on the 5th of August on the firm ice 

 (p. 251). ^
