two for extinct types, Cetotheriine and Cetotheriopsine. But while 
suppressing the subfamilies, he has retained the characters, the 
want of which induced me to frame one of them, in the diagnosis 
of the family itself. Im other words, the subfamily Agaphe- 
linæ was named for forms of Balenopterids. distinguished by the 
absence of pectoral folds and of a dorsal fin, yet Dr. Brandt, 
while suppressing it as unworthy of subfamily distinction, con- 
siders the development of such folds and of a dorsal fin as family 
characters.* The development or not of the folds and fin is 
certainly not of family value and should therefore be eliminated 
from the definition of the family, as it misleads both as to the 
prevalence of the characters and their value, and at the same 
time diverts the identifier from the path. Whether the characters 
are of subfamily value is another question, and one which need 
not be discussed here. 
In conclusion, it appears that I share the opinions of Dr. Brandt 
on most of the questions discussed, and I am happy to find that 
I can enroll myself under the banner of so able a leader; and I 
decidedly protest against being held responsible for views which 
I am as willing to oppose as he. As to the other points in 
which we appear to differ, I am fain to believe that it is due to the 
use of language more comprehensive than was meant by Dr. Brandt, 
and with the disposition to exercise that allowance for ambiguity 
which I would wish to have practised in respect to myself, prefer 
to surmise his real views from the general tenor of his works and 
thought, than to accept his exact phraseology.
