D. 16 — 18 (generally 17, rarely 15); A. 4; P. 15—17; Rings 

 II + 33—37 (generally 36). 



Head r.2 — 1.6 in trunk. Trunk 1.5 — 1.7 in tail. Snout straight, 

 1.9 — 2.5 in head, equal to or one eyediameter longer than 

 postorbital part of head. Eye 6 — 8. Coronet generally rather 

 low, obliquely directed backwards, with 5 more or less distinct 

 tubercles. Supraorbital tubercles generally well developed, in 

 front of them at each side a much smaller and often almost 

 inconspicuous one. Opercle with radiating ridges, often indistinct. 

 Occipital keel behind coronet without spines, at most having 

 a rough edge. Tubercles on cristae sometimes well developed, 

 in other cases small and blunt. Those on first, fourth and 

 seventh body ring and first, fifth, eighth, tenth or eleventh, 

 fourteenth and seventeenth tailring sometimes enlarged. The 

 shields are generally smooth, more or less distinctly ridged, 

 sometimes and not only in young specimens covered with 

 small tubercles. Filaments on tubercles very seldom present. 

 Dorsal on two last bodyrings and two first tailrings. The 

 ridge which carries the dorsal fin is low, much lower than in 

 //. hippocajnpus and the fin itself is much lower too. Colour 

 of alcohol specimens very variable. Generally dark brown or 

 black or brown with transverse black bands or elongate dots, 

 with or without numerous white spots. Sometimes yellowish 

 brown individuals occur, in which the tubercles and cristae and 

 especially the crista abdominalis trunci are darker. Still other 

 specimens are brown with large white dots, forming irregular 

 bands. Dorsal generally with a dark subterminal band. Length
