204 FISHES OF WESTERN SOUTH AMERICA 
The Peruvian specimens differ from the types taken in British Guiana (Lori- 
cartichthys brunneus) in having a distinct bar across the back, on the first two scutes 
opposite the dorsal, in addition to the five behind the dorsal; one of the specimens 
with the margin of the lower surface of the caudal plates dark, caudal with a basal 
dark spot; margin dark in one, the entire caudal fin behind the basal spot spotted 
in the other. 
The lateral keels not completely coalescent. 
15397, 2, 82-97 mm. to tip of middle caudal rays, Rio Pacaya, Allen, August, 1920. 
15982, 1, 123 mm., Iquitos, Allen, September, 1920. 
Color of 15982 from Iquitos much lighter, markings indistinct, apparently 
accounted for by the greater amount of silt prevalent in most waters about Iquitos, 
although in this respect the Pacaya specimens are intermediate, and the river only 
moderately opaque at the time when I was there, brown in color, not turbid. The 
Rio Pacaya specimens lack the ocellus in front of the dorsal; the basal caudal spot 
present.
