This subspecit's is so far known only as a native of a lew ixuids in 

 northeastern Massachusetts near the town of Danvers. Such a limited 

 distribution for a land vertebrate is remarkable, as is als(» the fact of 

 its having so loti^' remained without introduction to science. It has 

 been known and noticed by .scientilic men of the neinhborlnxtd, it sei'ins, 

 for twenty years. 1 aitpend a letter of its only historian, S. P. Fowler, 

 to my friend F. \V. Putnam, who.se name the latter has«'onferred on it. 



Ainonjjf eighteen si)ecimeiis of this subspecies forwarded to me by 

 the lOssex Institute of Salem, one female exhibits witlely .separated sii- 

 l>erciliary rid^res; in a iiiiieteeiith, from New Harmony, Iiid., the rid;;('s 

 are a little more dii"<'ro;cMit and less aseendin^i, with scarce a trace of 

 the median supra|>arietal elevati<ui. A specimen of the var. America- 

 nils from Nebraska approximates sulliciently closely to the last sjjeci 

 men to indicates that the l-'owleri can not be regarded as under all .cir- 

 cumstances .separate or be accorded full specilli; rank.
