Althon^di tlie form wiiidi presents this sin^^idar eliaraeter is not typ- 

 ical of the species, 1 do not consider it to lie referable to any other. 



IJesides the original two specimens of (Ireeii, I have seen threeothers 

 bearinff cirri, which 1 took with two noncirrigerous ones on the slope of 

 tlie IMack Mountiiins of Nortli Carolina. These specimens are otherwise 

 of typicid ciiaracter. 



Tlie cirrus is a larval character retained, which, were it peinianenr, 

 wouhl be of ;>eneric value; but it is not so, and in this case an individ- 

 ual feature only. The same peculiarity I have observe<l in two speci- 

 men; of S. chirnplcrKs sent by Sumichrast from Mexico, and in speei- 

 nuMis of S. lotiijicnwUis and S. (jiiltolinv(itiis I'roni the I'nited States. 

 The other charai^ters of this variety, thonjih marked, are nn)ddied in 

 various intermediate dejjrees in individuals from various, especially 

 southern, localities. The form of the tail is Just as in the typii-al variety, 

 though Ilolbrook has stat«-d them to diller. 



This species is very al)undant in Tennsylvania, and exteinls its range^ 

 with decreasing nund)ers, to iMaine. It differs in its habits from the 

 .V. Umgicnndus in being to a great extent a water animal, and less fre- 

 quently found under bark and stones. It is oidy in shallow, stony 

 brooks that it occurs, however, and ciin not be called a<piatic in the 

 serse in which the Tritons are. It is very active, and wriggles and 

 runs from the jiursuer in thesanienninner as, and generally in company 

 with, the Ih'smognathm fiisca. It is one of those species whose meta- 

 morphoses arc prolonged and which remains in the larval state until 

 nearly grown. 



This species appears to be the one to which must be referred the
