108 ON TEXAN REPTILES. 



calling for lighter color under the neck these snakes are 

 exceptions ; they are darker anteriorly and spotted nnder 

 the neck. The lighter color of the entire hinder portion 

 of the body apparently indicates that the species is in the 

 habit of lying in cover with but half of the length exposed. 

 This is Masticophis Jlavigularis of Bmi'd and Girard. 



Cyclophis vernalis ^De K.) Harl. ; Gthr. 

 Labials 7, infralabials 7-8, scutes 143 + 71, and 139 



+ 85. 



Philophyllophis majalis B. & G. ; Garm. 



Labials 7, infralabials 8-7, scutes 166 + 117, and 

 164 + 115. This form seems to have a greater number 

 of scutes under the body and a smaller number under the 

 tail than P. cesiivus. On the latter the body has about 

 155, and the tail about 130. 



The genus Philophyllophis was founded for Coluber 

 CBStivus of Linne. That species was placed in Opheodrys 

 by Fitzinger, 1843, followed by Cope. Gunther, 1858, 

 placed it in his Cyclophis the type of which is C vernalis^ 

 a form we can hardly regard as congeneric. The word 

 Opheodrys is a play upon the roots of Dryophis of Boie, 

 1827. 



Pantherophis Lindheimerii B. & G. ; Garm. 



According to the original description of this species it 

 diifered from P. alleghaniensis in having twenty-nine rows 

 of scales and a lighter coloration. The live specimens at 

 hand agree with these statements in regard to colors, but 

 difier in having only twenty-seven rows, thus agreeing in 

 this respect with the species from the northeastern states. 

 The differences between P. alleghaniensis and P. Lind- 

 heimerii parallel those existing between the Colubers, C. 

 constrictor and C. Jiaviventris. Instead of the glossy black
