that the side of the nail of the middle toe is considerably 
dilated, although not serrated, similar to what is observed 
among the Pelecanid(B. These characters offer a corroboration 
of the affinity of the Sternce to the family of the PelecanidcBy 
and particularly to the genus Phaeton, which approaches the 
Terns more closely than any other group of that family, in 
the smaller size of the membrane that unites the toes (see 
Linn. Trans, xiv. 505). It may also be stated on the other 
hand, that the same membrane of the Sterna 'pelecanoides 
deviates from its own genus, and approaches the PelecanidcB, 
in its being more dilated than usual. The wings are longer 
than the tail for a considerable extent, by which our bird also 
evinces another character, in common with the long-winged 
Tacky petes, or Frigate bird.
