Native. Septal, Sylvestral. Rather peculiarly distri- 

 buted, in its total absence from Scotland, while it probably 

 occurs in nearly every English county. I am not prepared 

 to cite authorities for the Tamus in any of the following 

 counties ; namely, Berks, Bucks, Northampton, Cardigan, 

 Radnor, Montgomery, Merioneth, Flint, Lincoln, Cumber- 

 land, Isle of Man. Deducting these eleven from the fifty- 

 two English counties (the Isle of Man being reckoned as a 

 county of itself, and Rutland not so) we have forty-one 

 only for the number of those which have been ascertained 

 to produce the Tamus. But as there are strong presump- 

 tions that it may be found in several among the eleven 

 counties above enumerated, I prefer to fix the comital es- 

 timate at 50, vvliich may be slightly too high, instead of at 

 40, which would certainly be too low.
