108 Mr. D. A. Bannerraan on the [Ibis, 



should turn up there at a time when P. k. fortanatus is 

 breeding. I am strongly inclined to agree with Messrs. 

 jNIathews and Iredale that Petrels and Shearwaters do not 

 wander hundreds of miles from their breeding quarters, and 

 I maintain that the African islands Shearwater must bear 

 the name I bestowed upon it, until it is proved to be 

 undoubtedly the same as the American bird. When this 

 has been done to my satisfaction I shall be the first to sink 

 my name and make it a synonym of P. k. borealis. As yet 

 I am not convinced that I am in error. 



Mr. Francis Harper, of the American Biological Survey, 

 has most kindly got together all the available data referring 

 to P. k. borealis in American waters, lie writes me under 

 date 17 August, 1919, as follows : — "I have just managed to 

 collect for you some data on the North American occurrences 

 of Puffinus borealis. It is known on this side only from 

 Long Island, Rhode Island, Massachusetts, and somewhat 

 doubtfully from Labrador. 



"Tiie Long Island dates range from August 6 to Octo- 

 ber 18 ; the Rhode Island dates from July 21 to November 16: 

 and the Massachusetts dates from August 2 to October 16 

 and perhaps November. 



'^ On August 8, 1915, Murphy and I collected seven 

 specimens, together with an equal number of P. gravis, off 

 Montank Point, Long Island, and saw a number of others. 

 There were four males (length in llesli 19"87-22'o0 in.) and 

 three females (2]*25-22'25 in.). The testes of the males 

 were small, and either white or half-pigmented ; the ovaries 

 of two iemales were noted as 'small': of the third, ' ^ in. 

 long.' 



'^ Colors of soft parts as follows : ' Bill straw-yellow, an 

 obscure dusky band across the bases of the nails. Tip and 

 edge of upper nail also dusky. Iris dark olive-hrown. 

 Outer side of tarsus, outer toe, under side of all toes, dusky, 

 with a pinkish tinge, irregular area toward tip of webs 

 dusky. Rest of webs, inside of tarsus, upper side of two 

 inner toes, flesh color, with pinkish tinge. Nails horn color, 

 with a dusky streak on each side extending to tip." "
