700 EIGENMANN— SIXTEEN NEW PYGIDIID^. 



Habitat, Rio Parahyba. 

 7074 C, type, 131 mm. Juiz de Fora. June 9, 1908, presented by 

 Dr. Ribeiro. 



In general appearance like Liitken's figure of hrasiliensis, dif- 

 fering notably in the position of the ventrals. 



Head 5.4 in the length ; D. 8.5 ; A. 8.5 counting in each case 

 the two rudimentary rays; P. 7; width of the head nearly equal to 

 its length; eye in middle of the head, interocular three in the length 

 of the head. Teeth conic, in bands. Right nasal barbels reaching 

 to above base of the opercular spines, maxillary barbels of right side 

 nearly as long as head, reaching to the second fourth of the pectoral, 

 both shorter on left side ; pectoral rather narrow, the outer ray 

 much prolonged, as long as head behind the nasal barbel, the fin 

 without the filament equal to the part of head behind a point mid- 

 way between eye and posterior nares ; origin of ventrals under 

 origin of dorsal, equidistant between base of middle caudal rays 

 and last third of pectorals, ventrals reaching much beyond vent, 

 almost to anal, equal to the snout in length ; origin of anal under 

 penultimate ray of the dorsal, distance between the base of its last 

 ray and the base of the middle caudal ray a little more than five in 

 the length ; caudal rounded, six and one third in the length ; dorsal 

 short, rounded, the distance between its origin and the base of the 

 middle caudal rays one and sixty-seven hundredths in the distance 

 between its origin and the snout. 



Sides and back profusely covered with confluent spots which 

 leave the light color as irregular vermiculations.

It is probable that the young specimens mentioned by E. & E. 

 belong to this species.
