extending so far inward, and contain fewer teeth. Parasphenoids 

 in an incompletely divided patch, as in P. glutinosus. Costal grooves 

 17, counting axillary and inguinal. Appressed limbs fail to meet 

 by 4| interspaces, compared with 3 in P. glutinosus. The whole 

 form of the body is much more slender, or slimmer, than that of 

 P. glutinosus, the tail longer and the head and body cylindrical 

 throughout. Toes webbed and with 2 joints free. 



Color bluish-plumbeous above and unmarked. Below brownish- 

 plumbeous, occasionally with a few small white spots along mid- 

 lateral line, where dark dorsal color fades into lighter ventral color. 

 Legs colored like body. Throat lighter than the belly and mottled 

 with white.

 No. 17,231, Port Allegany, McKean County, Pennsylvania, June 9,

 Indiana County, Pennsylvania, fall, 1908 (R. W. Wehrle); Nos. 

 19,114 and 19,115, Two Lick Hills, Indiana County, Pennsylvania, 

 September, 1911 (R. W. Wehrle); Nos. 19,118 and 19,124, same 

 data as last. 



This new salamander appears to be closely related to P, metcalfi 

 Brimley, except that it is slimmer and with more costal grooves. 

 It is probably a northern offshoot of that form. Further, it appears 

 isolated, and, with the present state of our knowledge, necessary to 

 admit it as distinct. Quite remarkable is the fact that it should 

 have remained so long unnoticed or confused with P. glutinosus. 

 The maximum length of our examples is 139 mm., and the minimum 

 length 44 mm. 



(Named for Mr. R. W. Wehrle, who collected most of our examples, 

 and also presented many local collections of cold-blooded vertebrates 

 to the Academy.)
