moderately fine. Color in alcohol uniform dull brownish 
generally, little paler below. Length 178 mm, Rio Janeiro,

O. scapularis Fowler 4s a synonym, ‘The dark scapular 
plotch, so conspicuous in the fresh fish, fades with tong 
immersion in spirits. A comparison of the type, in the 
Academy, with the atove example, besides other Academy 
examples from Rio Janeiro and Colon, 162 to 170 mm., long, 
shows all in agreement. The older specimens have faded 
pale and are without markings, 
QO. ends 14 fontee may represent the young, and 
thus be simply an accidental straggler to Rhode Island, 
where it was obtained many years ago. +t shows several 
characters which do not appear conclusive to us as char- 
acters of immaturity. ‘the scales above the lateral line 
are in rows longitudinally parallel with the same its 
entire course and in greatly reduced numbers as compared 
with O. ruber, The scales of 0. nein 4 show 7to 9 radi- 
ating basal striae, and 27 or 28 apical denticles, 
OQ. poeyi (Scudder) Posy” we have not seen, and 
though it is described with different coloration most of

tion for 0. ruber. It however, seems to be founded on a 
more slender individual, the depth 3; according to Jordan 
and Fesiler,
