Height 12 — 18; head 6 to S-'/j, 1.7 — 2.9 in trunk. Tail equal 

 to or slightly longer than head and trunk. Eye 7 — 10, about 

 I ' ., time.s in snout, which goes 5'/^ to more than 6 times in 

 head. Cleft of mouth horizontal, at least in adults not closing 

 completely, reaching far behind eye, twice to nearly three 

 times in head. Origin of dorsal before gillopenings, which are 

 rather wider than eye. Maxillary teeth in 2 series, an outer 

 one of about 13 to more than 20 small, subequal, compressed 

 teeth inclined backwards, and an inner series of 8 or more, 

 stouter, conical teeth. There may be in young specimens a 

 third outer series of small, soon disappearing teeth. Intermaxillary 

 plate with an outer series similar to the outer maxillary ones, 

 inside of them a group of caniniform teeth of which 2 — 3 

 median ones are the strongest. On vomer a single or an incom- 

 pletely biserial series. In each mandible a series of about 20 

 to 30 compressed, subequal teeth, inside of them anteriorly 

 about 6 canines. These teeth as also the inner maxillary ones 

 and those on intermaxillary plate are depressible. The colo- 

 ration shows many varieties of which the following have been 

 observed in our region. 



a. Brown with numerous white or yellow spots; gillopenings 

 may be black {i/tch-agris, c/i/orostigiiia). 



h. Brown with numerous more or less distinct and more or 

 less distant small or irregularly ovate or transverse black 

 spots {buroensis, grisco-badius Blkr., duivcnbodi), sometimes 

 almost uniformly brown. 

 Outside our re^ion the most distinct varieties are:
