This, perhaps the most abundant salamander in North America, is 

 (luito variable in coloration, but not in proportions and struettiral jte 

 culiarities. Tiio.so of the latter which characterize it are the presence oi' 

 fourteen costal plicae; one well, and one little developed lateral se- 

 ries of mucous pores; the equal and regular distribution of teeth on 

 the mandible of males ; the compressed tail keeled above and tinned 

 distally ; the presence of a tubercle in the anterior canthus of the e.ve ; 

 the marbled color of the belly. In many quarts of specimens I lind 

 four specimens from southern localities; two in tlie I'hiladelpliia AiMd 

 eniy from Charleston, two in the Smithsonian from IJiloxi, .Miss., whicli 

 have fifteen plica', but one of the latter has fourteen on one side. In 

 specimens which have been preserved in too strong spirit th(5 pores 

 are rendered invisible; the same occurs when the spirit is impure or 

 weak. In soft specimens, the canthal tubercle sometimes disappears, 

 and in many young si)ecimens and some sidult females it does not ap- 

 peal' to exist. 



The head is more depressed and the muzzle prolonged than in species 

 of other genera. The eyes arc piominent; llic plica' behind them 

 strongly marked. These consist of one on each sitle the head and nape, 

 which convei'ge posteriorly and then turn abruptly outwai'd, to be 

 continued into the gular plica. A secLMid plica extends from the man- 

 dible across the rictus oris to the upper plica. A second longitudinal
