Dorsal spine 2 times in length of head. Its posterior mar- 

 gin coarse, but without distinct serrae. First dorsal fin about 

 1 ^2 in head. Second dorsal largely replaced by a pad of fat, its 

 rayed part containing only 15 rays. 



Praeanal region 2,5—2,7 in total length (s. c). Anal part 

 of caudo-dorsal fin with about 80 rays. 



Pectoral spine somewhat longer than dorsal spine, 1,9 in 

 head, its hindborder is serrated. Pectoral fins well reaching ven- 

 trals. Ventrals rounded, as long as snout or distance from tip 

 of upper jaw to middle of eye.

First branchial arch with 6 -|- 20 gill-rakers, its inner side 

 with a short menbrane with rounded papillae. 



In the specimens from Glencoe, the color is a light browm, 

 paler below. The barbels are light or shaded by a fine dark 

 pigmentation. The fins are also fight colored, they show, how- 

 ever, traces of a darker coloring, especially marginally. In one 

 specimen, the pectorals are blackish for the apical half. It is 

 impossible to state if the coloring mentioned above is caused by 

 fading in the preserving fluid or not. The specimens from Her- 

 mit Hill have a very pronounced dark brow^n color with the 

 lower parts lighter and the ventral surface from the mouth to 

 the anal fin very pale. All the barbels are blackish, the mandi- 

 bulary ones setting off very sharply from the pale ventral parts 

 of the head. Fins dark on account of a fine dark pigmentation.
