Between Knoxville and Cade's Cove, 35 miles, the following are 

 found, Poly, elevata, form cincta, Taylor; Poly, spinom (Lea);

A NEW PHILOMYCUS. 



BY T. D. A. COCKERELL. 



Philomycus secretus n. sp. 



Length (in alcohol) 12 mm Mantle very dark grey, with numer- 

 ous small black spots, best seen at the sides. Body pallid, sole whit- 

 ish with an ochreous tint. 



Jaw light yellow, arched, with five strong ribs in the middle, 

 nearly the outer thirds being ribless. Teeth 9-11—13-1-13-11-9. 

 The side cusps on both centrals and laterals are very small. Penis- 

 sac as Binney describes for P. hemphilli. 



Hab Roan Mtn., Mitchell Co., North Carolina. (A. G. Weth- 



erby.) 



Mr. Wetherby sent me two specimens with these remarks : "A 

 small slug found here which I am quite sure has never been de- 

 scribed. It is never larger than these specimens ; lives deep down 

 in drifts of damp leaves, and never comes to the surface so far as my 

 careful observation of it for the last ten years goes to show. It is 

 "sluggish" in its habits; about all it will do when brought to the 

 light is to cautiously protrude its very short tentacles." (Litt., March 

 22, 1899.) 



By its jaw characters, this resembles only P. hemphilli. From 

 that, as described by Binney, it differs mainly in being only half the 

 size. Mr. Wetherby knows both species, and states that the present 

 animal is uniformly small ; further, although I was not able to make 

 a satisfactory examination of the anatomy, the genital organs appear 

 to be fully developed.

In a former paper on Japanese snails, I identified a species of 

 Eidota from Ushika, prov. Teshio, with the Helix Iceta of Gould, but
