THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 147 
are only very slightly keeled below. ‘The number of chevrons cited by Lilljeborg 
is two more than in any American specimen of 2B. physalus I have examined, but 
Flower’s Falmouth (Eng.) specimen had the same number as the Greenland 
skeleton, as will be seen by reference to p. 139. 
Lilljeborg’s measurements are as follows:

OPINIONS OF EUROPEAN CETOLOGISTS REGARDING THE OCCURRENCE OF B. PHYSALUS IN 
AMERICAN WATERS. 
In the Ostéographie (8, 236) Van Beneden and Gervais express the opinion 
that Cope’s Stbbaldius tectirostris is probably the same as 6. physalus (for which 
they use the name B. musculus), but they had not seen the type, nor did they enter 
into any discussion of the subject. In 1889, again, Van Beneden includes Green- 
land in the range of this species, probably on the basis of the observations of Fa- 
bricius (7, 224), and remarks, “various authors have reported it at New England,” 
referring doubtless to the observations of Dudley, Cope, and Allen. 
‘Swedish measure.
