OF LANCASTER COUNTY, 575 



THYROSTERNrM pensylvaiiicum, Ag. The two last named species have a imusky (xlor 

 and are called stiuk pots. The first can readily be distin^ruished from the Hccuiid 

 by its more deeply marked scales and the small lleshy warts inider the chin. 



ORDER 11. SA URIA— LIZARDS. 

 We have but t^yo kinds 

 Tropidolepus undulatus — a brownish species with diagonal markings of l)lack stripes 



and spots. 

 SciNcrs fasciatus— the five-striped lizard ; a specimen from East Florida appears to bo 

 identical with ours. 



ORDER III. OPIIIDIA or SERPENTS. 



Family — Crotalid.e. 



Crotalus horridus— "Bastard Rattle-snake," without the rattle; venomous; rare. 

 Distinguished from the true rattle-snake mainly by the absence of rattles. Occa- 

 sionally along the mountain ranges specimens may be found. 



Trigonocephalus contortrix, Holb.,—\\\e "Copperhead"; venomous. This reptile is 

 still found in the county, and especially along its wild southern border, where in 

 some localities, it is by no means rare. 



Family — Coluberidje. 



Bascanon constrictor, B. ^' 0. — Black-snake — by way of distinction called the racer. 



Not venomous. 

 ScoTOPHis allighaniensis, B. §■ G. — Also a common black snake, but not so slender as 



the racer. 

 Nerodia sipedon — common water snake; abundant, but harmless. 



fasciata — a very pretty mottled species of water snake. 

 Regina lebris — subaquatic in its habits. 

 ExTAiNiA sirtalis — the common garter snake; also resorts to the water in pursuit of 



tadpoles and other species of aquatic animals, 

 sauretia — the swift garter snake, also called the "ribbon snake"; is more slender, 



and the stripes broader and more distinct than in the common species. 

 Ophibolus eximeus — the common "hoiise snake""; is beautifully mottled with brown 



spots, with dark margins on a light ground. A specimen three feet long was cap- 

 tured near Lancaster, and is now in the Museum of the Linniean Society. 

 Heterodon platyrhines — commonly called the "Viper" or "Blower"'; but unlike the 



true viper, which is a foreign species, it is entirely harmless, although sometimes 



making a great show of pugnacity. 

 DiADOPnis punctatus — the ring-necked snake; is not rare. 

 Storeyia deKayi— quite common within the limits of Lancaster city, with small 



black spots along the dorsal line and sides; color in larger specimens of a 



brick red. 

 Celuta amoena — ground snake, or worm snake. 



It may be added in conclusion, that there are persons now living in the county of 

 Lancaster, who verily believe they have seen a species of green-snake within its limits 

 many years ago, but no recent case has occurred in confirmation of such a belief. 



IV. ORDER BATRACniA— FROGS AND SALAMANDERS. 



Family — Urodelid^e. 



SALAMANDRAerythronota— the most common species, under stones and logs; dark color 



with a yellowish dorsal stripe.
