The CMlognatTia perhaps ought rather to be considered a sub-order of the Diplopoda 

 than the Chilopoda. They are diplopod in their pedal characters, and still have the flat- 

 tened bodies of the chilopods, Avith the legs articulated at the sides. The Class is cut 

 up into many orders, sub-orders, sub-families and sub-genera, to which, in a limited 

 list, it was not thought necessary to adhere. Nor can it be supposed, from the little 

 that is absolutely known of the local myriapoda of Lancaster county, that this list 

 includes all the local species. Sufficient are however enumerated and arranged, to give 

 some idea of what the county contains. With but limited material, assisted by the 

 excellent paper of Dr. Wood of Philadelphia, this list has been compiled. 



IIERPETOLOGY.i 



REPTILIA, CLASS OF REPTILES. 



The animals belonging to this class have been long and tolerably well known under 

 the common names of Turtles, Terrapins, Snakes, Frogs, Toads, Lizards, Salamand- 

 ers, Newts, &c., and although generally harmless, the larger portion of our population 

 regard many of them with feelings of aversion. The class is usually divided into four 

 orders, namely, C HE L ONI A, 8 A URIA, OPUIDIA and BABTBACHIA, only a small 

 number of species of either of which are known to inhabit Lancaster county. 



ORDER I. CEELONIA or TESTUDINATA—TURTLES. 



CiSTUDA clausa — the common "land tortoise" or "box turtle;" sparsely but widely 



distributed over the county. 

 Chelydra serpentina — the well-known "snapping turtle;" very much prized by epi- 

 cures, and found in all our streams, especially in ponds and mill-dams. 

 Emys (Graptemys, Ag.,) geographica — the j^eculiar yellow curved map-like lines with 



which it is marked gave rise to the specific name. 

 (Chrysemys, Ag.,) picta — the scales of the carapace are beautifully bordered with 



yellow, and the base with red markings, hence the common name of "painted 



terrapin." 

 (Nanemys, Ag.,) guttata — is distinguished by small yellow spots on the black 



carapace; numbers are often associated together in the same pond, and sunning 



themselves on a log, stone or stump, in the water. 

 (Glyptemis, Ag.,) insculpta — A pretty species, scales of the shell deeply grooved 



in radiating lines from an elevated centre — legs and neck deep-orange coloi'ed 



when young. 

 (Ptychemys, Ag.,) rubriventris — a doubtful species, 

 megacephela ? — the large river terrapin ; at one time exceedingly numerous in the 



Susqviehanna river, but now becoming rather scarce. It is considered next in 



excellence to the snapping turtle. 

 OzoTHECA, Ag., odorata — commonly called the "stink pot."
