THE BIRDS OF NEW JERSEY. 69 



104 Thalassidroma pelagica (Linnaeus). 

 Storm Petrel. 



Adults. Length, 5.50-5.75. Wing, 4.50-4.90. Plumage similar to that of 

 Wilson's Petrel, from which it is easily distinguished by its smaller size and 

 much shorter feet tarsus, .90-.95. 



There seems to be no record of this species from New Jersey, nor is 

 it certain that it occurs even off our coasts. The only evidence of the 

 latter is a statement of Lawrence's for New York, and one of Krider's 

 referring to a specimen secured at Philadelphia after a storm. 1 The 

 little Petrels were so much confused in the old days, however, that 

 these statements might easily have referred to either of the other 

 species. 



106 Oceanodroma leucorhoa (Vieillot). 



Leach's Petrel. 



/ 



PLATE 6. 



Adults. Length, 7.50-8.50. Wing, 6-6.25. Entire plumage, sooty brownish- 

 black, except the upper tail-coverts, which are white, somewhat mottled with 

 blackish ; tail, distinctly forked ; feet, entirely black. 



Pelagic, occurring off our coast during the autumn and winter, 

 retiring to the coasts and islands from Maine northward to breed. 



Turnbull states that a number were driven inland in August, 1842, 

 during a 'gale. 



December 18th, 1890, one was taken by Mr. W. V. Wilbank, 2 on the 

 Delaware River at Tinicum, and Mr. I. N. DeHaven secured another 

 on the thoroughfare at Atlantic City August 24th, 1893. 2 Both of 

 these 1 have examined.
