272 Fretp Musreum oF Natura History — Zoéroey, Vor. X. 
Color very dark brownish green above, pale below; sides with 2 
lateral bands, partly broken into confluent black spots; dorsal, anal 
and both lobes of caudal each with 2 oblique, black bars; pectorals 
and ventrals each with more or less black mesially. 
Of this species only 3 specimens, respectively 105, 120 and 135 mm. 
in length, were taken. All are from the Rio Cupe at Cituro, where this 
stream is very rocky and seining is difficult. 
The variation in dentition in the specimens at hand has been noted 
above. From this it is evident that only the largest specimen, the type, 
is a typical Apareiodon. However, as no other differences are evident, 
we have identified them all as one species and we woe place them 
under the above named genus.
