Remai'h^. — The direct relationship of this new salamander is not 

 easy to trace. In the coloration of its legs it resembles very strongly 

 the Californian Pletliodon croceater^ which also has a long tail, but 

 here the similarity ends, for the shape of the head and the dentition 

 as described b}" Cope are entirely different, besides many other dis- 

 crepancies in relative length of toes, of limbs, and in number of costal 

 folds, etc. 



With our conmion eastern Plethodon glutlnosus the new species has 

 very little in common except the minute, pale, dust-like sprinkling of 

 the dark skin. The proportions are entirely different, P. shertnani 

 being much slenderer with a much longer and slenderer tail, while the 

 dentition is still more at variance, P. glutinosus having the vomero- 

 palatines extending Ijcj^ond the choanse and a single, undivided para- 

 sphenoid patch. The fifth toe is also relatively much longer than in 

 P. glutinosus. 



The proportions of P. seneus., on the other hand, are similar, except 

 those of the head, which in this species is broad and squarish. The 

 tail, also long and slender, is more cylindric though less tapering 

 toward the tip. The hands and feet are also very different, being 

 very broad and the digits distinctly widened at the tips (tig. 6). The 

 coloration, moreover, is radically different and the dentition almost as 

 much so, for while in P. shermani the teeth are large and few, the 

 -vomero-palatine series short, unusually far apart behind and placed far 

 away from the distinctly divided parasphenoid patches, in P. seneus (tig. 

 2) the teeth are small and ver}^ numerous, the vomero-palatine series 

 long, unusually close together behind and the parasphenoids on an 

 undivided patch. Finally, while in the former the choanas are large, 

 in the latter the}' are uncommonly small. 



Were it not that P. jordunl (lig. 3) has the parasphenoid patches 



divided by a narrow groove we would scarcely have needed mention it 



in this connection, inasmuch as proportions and dentition otherwise is 



sufficiently different. It is a much stouter built animal and the teeth
