ON THE EUTiENIiE OF SOUTHEASTERN INDIANA. 



BY E. D. COPE. 



In a collection of snakes sent me by my friend, Mr. A. W. Butler, of 

 Brookville, Intl., specimens of the genus Eutaenia B. & G. considera- 

 bly predominate. These include, as is to be supposed, the two usual 

 species, E. sirtalis L. and E. saurita L. The former is represented by 

 four strongly marked subspecies. Besides these, there are two other 

 distinct species which have not been hitherto observed in Indiana, to 

 one of which it is necessary to give a new specific name. This is unex- 

 pected, but shows what can be done by thorough collecting, such as has 

 beeu undertaken by the members of the Indiana Academy of Sciences. 

 I append a list of the species and subspecies, with descriptions of the 

 novelties : 



1. Eutaenia sirtalis sirtalis Lirm. Nos. 318, 359, and 360, typical. No. "275 (two 

 >peeinieus) in their obsolete lateral stripes are intermediate between this and the 

 next subspecies. 



2. Eutaenia sirtalis ordinata L. 292, 314. 



3. Eutaenia sirtalis graminea Cope. Subsp., nov. 



This form is a uniform light green above, below yellow clouded with 

 green. Lips, chin, and throat uniform yellow. No stripes or spots on 

 the body, nor markings of any kind on the head. Scales 19 rows ; supe- 

 rior labials, 7; temporals, 1-3, first large; gastrosteges, 150; anal, 1; 

 urosteges, 66 pair, four of the latter undivided; lowest row of scales 

 smooth; length, 495 mm ; tail, 107. 



This form is the extreme in the direction taken by the E. s, ordinata, 

 where the bands are entirely wanting, but the quadrate lateral spots 

 remain. In the entire absence of black marks on the labial and ab- 

 dominal plates, this form differs also from its immediate allies. The 

 coloration in that of Cydophis cestivus. One specimen, Xo. 295. 



4. Eutaenia sirtalis obscura Cope. This form resembles at first sight the E. saurita. 



Nos. 319, 321. 



5. Eutaenia butleri, sp. nov. 



Scales in nineteen longitudinal rows, the inferior much the widest and 

 keeled. Superior labials seven. Temporals, 1-1 ; the second large, ex. 

 tending from parietal to labials. Oculars, 1-3. Parietals with the ex- 

 ternal border abruptly contracted. Gastrosteges, 144; anal, 1; uroste- 

 ges, 62. Head very little distinct, muzzle conical, a little protuber- 

 ant; eye not large. Ground color, above olive brown, which is marked 

 by the usual three longitudinal yellowish bauds. The median covers 

 one and two half rows of scales, and the lateral covers the second, 

 third, and fourth rows. Both are black bordered on both edges, the
