of the snout, much shorter than the parietals ; one pree- and 

 two postoculars ; temporals 1 + 1 ; six upper labials, second 

 and third entering the eye, fifth largest ; four lower labials in 

 contact with the anterior chin-shields, which equal the pos- 

 terior in size. Scales in 15 rows. Ventrals 203 ; anal 

 divided; subcaudals 26. Cream-colour (in spirit), above 

 with three black streaks, interrupted by the pale borders of 

 the scales, the middle one on the vertebral row of scales, the 

 lateral between the fourth and fifth rows (counting from the 

 ventrals) ; a blackish transverse band on the base of the tail ; 

 ventrals and subcaudals black antero-mesially. 



Total length 530 millim. ; tail 45. 



A single specimen, from the Camapuam-Rivcr district. 



Pimelodas [Pseudorliaindia) nicjriharhis. 

 D. 1/6. A. 17. P. 1/8. 



Head bony above, granulated; occipital process obtusely 

 keeled, twice as long as broad, extending to the basal bone of 

 the dorsal spine. Adipose fin one sixth of the total length 

 (without caudal), about two thirds its distance from the dorsal 

 fin. The maxillary barbel extends to the origin of the anal, 

 the outer mandibular to the extremity of the pectoral. Length 

 of head two sevenths of the total (without caudal) ; eye rather 

 larger, a little nearer the end of the snout than the extremity 

 of the opercle, its diameter once and a half in the length of 

 the snout. Dorsal fin much higher than long, the spine 

 strong, but little shorter than the anterior branched rays, 

 measuring two thirds the length of the head. Pectoral spine 

 a little longer than dorsal, serrated on both sides. Caudal 

 fin deeply forked, with the lobes pointed, the upper being the 

 longer. Upper parts and fins powdered with black, most 

 closely on the ventrals and anals and on the barbels, which 

 are almost black. 



Total length 155 millim. 



Two specimens, from the Camapuam River. 



Girardinus Iheringii. 



D. 9. A. 9. V. 5. L. lat. 28-30. L. transv. 8. 



Height of body about two sevenths of the total length 

 (without caudal), length of head one fourth. Diameter of 

 the eye exceeding the length of the snout, less than the width 

 of the interorbital space. Origin of the dorsal above the 

 middle of the anal in the female, a little nearer the end of the
