eyes ; teeth forming õ series in the upper jaw, 4 

 in the fower ; 9 g-ill-rakers on the lower part ot 

 the anterior arch. Dorsal slightly increasing to the 

 8 th. spine, which is three times in the head, the 

 21 th. only very little longer ; 7 th. solt dorsal the 

 longest, equal to base of soft dorsal plus 2 spines. 

 Pectoral and ventral extending to the vertical of 

 the 12 th. dorsal spine. Caudal peduncle somewhat 

 longer than deep. 



Brownish, tips of both lips black, a very short 

 oblique strip below the eye, another longitudinal 

 from the eye to tiie pectoral; beginning by this fin, 

 a series of nine vertical bars until the first, scale of 

 the lower ramus of the lateral line ; the following 

 scales of the lateral line are white on the anterior 

 half and black on the posterior ; no caudal spot. 

 Vertical fins with several series of dark spots (three 

 on the anterior dorsal, four to five on the posterior 

 part). Pectorals and ventrals colourless. 



A third specimen from the same river is so- 

 mewhat larger, 135 mm, D. XXII, 1!; A. I1I,S ; 

 pores ^f; 57 scales in the first series below the 

 lateral line. The general colour is somewhat dar- 

 ker as well as the dorsal fin, which lias only some 

 dark spots between the soft rays. It seems how- 

 ever to be the same species, which has brighter co- 

 lours in the youth.

Our species from the Mucury-systeme, a small 

 river which empties into the sea above the Rio 

 Doce, seems to be the nearest relative of Cr.yr/_^oii- 

 rensis Hasem., hitherto known only from Jagoára, 

 Rio Grande, from the Paraná-systeme, Minas-Geraes.
