eye. The origin of the ventral a little behind that of the dorsal. 

 Ventrals a little loager thau the pectorals. Distance between dor- 

 sal and caudal two-sevenths of the length of the latter. The lon- 

 gest dorsal finrays extending over the first third of the caudal. Cau- 

 dal rounded. Body (in spirits !) brownish with dark blotches between 

 the eye and the gill-opening. Sides of the body with four or five 

 dark, broad, vertical bands, which continue on the base of the 

 dorsal. Vertical fins more or less irregularly striated with black. 

 Three specimens with a total length of 7 cm , 8,5 cm. and 9 cm. 



Atopochüus güntheri (Fig. 2 A and B) 

 D 1/6; A 10; P 1/9. 



This species agrees in several respects with A. Savorgnani Svge 

 (N. Arch Mus. (2) 1880, PI. III fig. 3, p. 42 and Buil. Soc. 

 Philom (7) III p. 97) , but differs from it in the number of anal 

 and pectoral finrays and moreover in the foUowing points: 



Height of the body one-thirteenth of the total length (caudal 

 included). Length of the head a little less than one-fiffch. The 

 greatest width of the head nearly equals its length. Maxillary 

 barbel more than twice as long as the diameter of the eye, a 

 very small mandibulary barbel: half the length of the diameter 

 of the eye. The arrangement of the maxillary teeth agrees with 

 H. E. Sauvage's description of A. Savorgnani. Mandibulary teeth 

 notched, placed in a great nuraber (circa 22) of transverse series, 

 consisting of circa 6 teeth each , and those of one half of the 

 mandible converging with those of the other half from before 

 backwards. Voraerine teeth conical, in a rather broad band. Eye very 

 small , placed between the second and last third of the length of 

 the head. Interorbital space nearly half the length of the head. The 

 humeral process does not reach the base of the dorsal spine. The 

 latter is not serrated , very short , shorter than the followiug finrays 

 and one-half of the length of the pectoral spine. Both , dorsal 

 and pectoral spine are fringed. The ventrals laid backwards, the 

 distance between them and the anal remains still more than half 

 their length. Caudal deeply forked.
