and it is now hard to resist the conclusion that. they have to be 
regarded as an “ Order,” to which the name TUBINARES has been 
applied from the tubular form of their nostrils, a feature possessed 
in greater or less degree by all of them, and one by which each may 
at a glance be recognized. They had been variously subdivided ; 
but to little purpose until the anatomy of the group was subjected 
to comparative examination by Garrod and W. A. Forbes, the latter of 
whom summed up the results obtained by himself and his predecessor 
in an elaborate essay (forming part ix. of the Zoology of the voyage of 
the ‘Challenger’) which shewed determinations that differed greatly 
from any that had been reached by prior systematists. According 
to these investigators, the 7'ubinares are composed of two Families, 
PETREL, Prion turtur. (After Buller.) 
Procellariide and Oceanitidx, whose distinctness had hardly before 
been suspected !—the latter consisting of four genera not very much 
differing in appearance from many others, while the former includes 
as subfamilies Diomedeinx (ALBATROS), with three genera, Diomedea, 
Thalassiarche and Phebetria, and the true Petrels, Procellariing, in 
which last are combined forms so different externally and in habit 
as the Diving-Petrels, Pelecanoides or Halodroma, the Storm-Petrels, 
Procellaria, the Flat-billed Petrels, Prion, the FULMAR, the SHEAR- 
WATERS and others. Want of space forbids us here dwelling on 
the characters assigned to these different groups, or the means which 
have led to this classification of it, set forth at great length in the 
essay cited where also will be found copious references to previous 
studies of the Petrels.” 
! Tt is due to Prof. Coues to state that in 1864 he had declared the genus 
Oceanites, of which he only knew the external characters, to be ‘‘ the most 
distinct and remarkable” of the ‘‘ Procedlariex,” though he never thought of 
making it the type of a separate Family.
