In alcohol the {general color is a livid black. There is a dorsal series 

 of transvi'rso lijjfht slate-i^olored bantls, which widen at ea<*,li end into a

 about seven on the body and as many on the tail; sometimes more or 

 less; sometimes (continent with those before and behind them; soine-

The principal dill'ereiice in I'orm and strnctnre between this species 

 and A. pumfatum aresec^i in the abseiuie of any dorsal furrow, and a less 

 proiniiien(u> of that on the side of the tail. The limbs are more feeble, 

 the head narrower, the tail shorter, et(t.

 more ('Iniiisy, tlie lej^s weaker, the toes shorter than in Pennsylvania 

 spj'cimens. The te«'th, too, api>ear more transverse, and there is little

This species is found in drier jiroiiiid than is conociiial to most sal 

 amanders. I have taki'ii it in tiu' sandy ri'^ions of New Jersey and 

 Delaware.
