 Ambltstoma opaca — terrestrial in their habits, but partial to moist localities, 

 Triton millepunctatus — this species is aquatic and has a membrane along the tail, fin- 

 like. There are perhaps other species inhabiting Lancaster county, as such have 

 been captured in adjoining counties. 

 Menopoma allighaniensis — this is the "hell-bender" of the fishennan; it is the largest 

 species known to our county, and within the past few years has become com- 

 mon in the Susquehanna, and has been captured at Safe Harbor, Columljia and 

 Marietta. A specimen in the collection of the Linnsean Society is nearly eigh- 

 teen inches in length. 



Family — Ranid.e. 



Rana ijipens — our most common species of frog. This species was at one time very 



numerous in the county of Lancaster, but being diligently sought by epicures as 



a delicate edible table relish, is becoming very rare, especially as its favorite 



haunts are rapidly being drained and giving way to cultivation. 



fontinalis — commonly called the "Bull-frog," and is distinguished from the common 



species by dermal folds along the dorsal line; one taken near Lancaster city, 

 halecina — the spotted or shad-frog, 

 sylvatica — the wood-frog, 

 palustris — the marsh-frog. 

 Hylodes gryllus — the small cricket-frog. 



Hyla versicolor — the northern tree-frog or tree-toad. There seem to be two kinds of 

 tree-frogs in Lancaster county, vTuless the difference in color is merely sexual; 

 one is a dark farm color, mottled with black; the other has small eyes, more 

 prominent and of a greenish color, with only a large blotch across the shoulders 

 and a dark band on the thighs. 

 BuFO americanus — the common toad; repulsive to some people, but at the same time 

 harmless and useful in gardens as an insect scavenger, 

 erythronotus — deemed a southern species, but found in the county.
