south. This region is more of a high plateau country than is the habitat 

 of schencki, where the dissection is more mature. The range of nitidus is, 

 then, that less dissected northern portion of the Southern Blue Ridge, 

 which is also the region of Leurognathns marmoratus and of Plethodon 

 yonahlossee. The type is remarkable in lacking a tongue, the slit for the 

 tongue stalk being a mere groove. This is evidently due to some accident, 

 but the animal seemed to be normal and to be getting along quite well 

 without its complicated hyoid apparatus. 



Eurycea gutto-lineata (Holbrook). 



Mt. Sterling (1800 feet), one adult and 16 larvae in spring; Anniston, 

 one adult in spring ; Morrisville, one adult in spring ; Crozet, tWQ,adults in 

 spring. 



Eurycea longicauda (Green). 



Mt. Sterling (1500 feet), one adult under a log in woods. 



New record for North Carolina. In the South, as in the North, this 

 animal seems to be working eastwards, but only north of the Potomac has 

 it made much headway. 



Eurycea bislineata bislineata (Green). 



Midway, 1 larva; Manteo, 1 adult; Abingdon (2000 feet), 2 adults, 

 1 larva; Spring City (1500 feet), 3 adults. 



It seems necessary, upon careful consideration, to separate the animals 

 of the Southern Blue Ridge as a race of bislineata. This race is almost 

 immediately recognizable, but it is rather hard to frame a definition, on 

 account of its variability in color. I name it for Mrs. H. H. Wilder, 

 who has done a great amount of work on the life history of the typical 

 form. 



Eurycea bislineata wilderae, n. sp. 



Type, M. C. Z., No. 5848, adult male; White Top Mt., Va., 4000 feet 

 (under log in woods) ; July, 1919; E. R. Dunn, collector. 



Diagnosis. — Similar to E. bislineata bislineata, but adult male usually 

 with cirri on upper jaw, and somewhat more slender in form, tail longer, 

 markings usually a narrow black line on sides, broken or absent on distal 

 half of tail. 



Description of Type. — Costal grooves 15, counting axillar and inguinal. 

 Four intercostal folds between appressed toes. Head width 6'/ 2 times 

 in length from snout to vent, head length 4'/2 times in length of body. 

 Head an elongate oval with blunt snout. Snout swollen, eye a little longer 

 than its distance from tip of snout. Sides of naso-labial groove, swollen 

 and prolonged into a cirrus whose tip is free and which is not an extension 

 of the edge of the lip. Outline of upper jaw convex as viewed from the side, 

 angle of jaw below eye and very narrowly separated from lower eyelid — 

 a short groove connects edge of lip with groove of lower eyelid. A groove 

 from eye along side of head almost to gular fold — latter on sides of neck to 

 just above insertion of arm. Vomerine teeth series closely approximated
