Article XIII. — A Si^nopsis of the Reptiles and Amphihians of 

 Illinois. By H. Garman. 



PKEFATOKY NOTE. 



This synopsis is presented largely as it was written several 

 years ago. Before a final report on our reptiles and amphibi- 

 ans is prepared, it is sincerely to be desired that examples of 

 every Illinois species may be in the Illinois Laboratory collection 

 for description, and that the local features of the fauna may be 

 brought out by a critical comparison of Illinois specimens with 

 collections from other parts of the United States. Specimens of 

 the following species, and observations upon them, are especially 

 desirable: Cistudo ornata^ Chrysemys picta^ Fseudemys hiero- 

 glyphica, P. concinna^ Heterodon simus, Ophiboliis rhomhomacu- 

 latus, Nerodia sipedon war. fasciata, Rana areolata, R. sylvatica, 

 Hyla cin«rea, Desniognathusfusca,Spelerpes ruber, Amblystoma 

 jefi'ersoniayinm and A. punctatum. 



A few additional species known to occur in adjacent states 

 may be looked for in Illinois. 



Chelopus guttatus may occur in northeastern Illinois. It 

 has been found in northern Indiana and in Michigan. 



Aspidonectes ferox has been found in the Ohio River, and 

 is likely to occur in this stream and in the Mississippi, along 

 our borders. 



Hyla squirella has been taken at Brookville, Indiana, by 

 Mr. A. W. Butler. It is a southern species, most likely to 

 occur in the south part of the State. 



Amblystoma copianum was described in 1885 by Prof. 0. 

 P. Hay from a single specimen taken at Irvington, Indiana. 

 It seems to bear a general resemblance to the young A. tigrinum 

 just from the water. It may be distinguished from all re- 

 corded Illinois members of the genus by the presence of eleven 

 costal grooves and two plantar tubercles.
