"snout, lips, maxillary and mandible naked or skin coriaceous, 
Color in alcohol uniform umber, little paler to slightly 
ochraceous below. Fins all dull brownish, dorsals little darker 
marginally and ventrals with innermost ray pale like belly, 
Length 300 mm, One without locality, doubtless from Rio Janeiro? 
Our example agrees in so many respects with Ribeiro's account 
end figure that we believe it to be the same species. In the 
deneric diagnosis Ribeiro says "“vomer provido de dentes curtos, 
obtusus, os palatinos d'una fila d'outros memores". Although 
the upper buccal fold is quite broad we cannot find any structures 
which may be considered as teeth or even denticles, The vomer is 
covered with thick, small, close-set papillae and few scattered 
papillae are found over the palatine region and elsewhere on the 
roof of the mouth, Other features, not in agreement, as given by 
Ribetro, are : D. VII, 28; A.27; lateral line with 88 scales; 19 
scales above lateral line. His figure does show, however, rather 
conspicuous upper front canines and preorbital apparently naked, while 
in our example the preorbital and shout are closely scaled. P.
