EIGENMANN: the PYGIDIID^, a family of south AMERICAN CATFISHES. 333 



nares, the filament extending very little beyond the other rays; ventrals nearly 

 reaching anal, their origin nearer caudal than to tip of pectorals; caudal rounded, 

 six in the length; origin of anal under middle of dorsal, distance between the base 

 of its last ray and the middle caudal ray 5.2 in the length ; origin of dorsal equidis- 

 tant from base of middle caudal rays and middle of pectorals, its last ray over the 

 middle of the anal, the distance between the origin of the dorsal and the base of the 

 middle caudal rays two in the distance between dorsal and snout in the type, 1.66 

 in the paratype. 



With many faint spots about as large as the eye ; in the type a dark streak along 

 the middle of the sides, another along the side of the back, and a third along the 

 edge of the belly. 



This species is similar in appearance to P. striatum, from which it differs in the 

 position of the ventrals, the pectoral filaments, etc.

These minute specimens came from near the type locality of P. paolence and 

 are probably the young; the ventrals do not reach the vent; there is a series of 

 minute spots along the sides, nearly confluent anteriorly; a series of larger spots 

 above it on the sides of the back and a series along the middle of the back.

Velhas. May 14, 1908. Haseman. 



Mr. Haseman notes that this is the only species he secured at the particular 

 locality where the only specimen of the present species was collected. 



Head 6.5; D. 9.5; A. 8.5, counting the minute rudimentary rays in both dorsal 

 and anal; P. 6; eye in anterior half of head; interocular three times in the head. 

 Teeth conic. 



Nasal barbel nearly as long as the maxillary barbel, which reaches the edge of 

 the gill-membrane. First pectoral ray with its filament equal to the length of the 

 head, much longer than the divided rays; ventrals reaching beyond the' vent, their 

 origin very little nearer tip of pectorals than base of middle caudal rays; origin of. 

 anal under middle of dorsal ; distance between the base of the last anal ray and the 

 middle caudal rays five and a half in the length; caudal narrow, a little longer than 

 the head, the accessory rays inconspicuous; origin of dorsal over middle of ventrals, 

 its distance from the middle caudal rays nearly two in its distance from the snout 

 (19 and 36 mm. respectively).
