one in the Academy collection obtained by Orton. The 
Wilkes examples are faded dull and nearly uniform brown. 
Synodontidse. 
Synodus japonicus (Houttuyn). 
The material in the collection seems to correspond 
in large measure to the characters of the present species. 
It apparently would represent mostly the dark or greenish 
phase ascribed to the species. Besides these we have in- 
cluded the examples in the Academy recently described as 
S. dermatogenys Fowler,(12) with the conclusion the same 
must be submerged as a synonym. It is based on 9 specimens, 
the type and 2 paratypes evidently representing the red 
phase, while the 2 remaining paratypes are likely the green 
phase. None of these examples show the large scales on the 
lower cheek, as indicated by Jorden and Evermenn.(13) The 
cheek below shows little or no indication of scales in 
most cases, and when so, the scales are always smaller
