differences. The light dorsal spots are smaller and more heavily outlined 

 with dark. They do not break up until the animal is practically mature 

 and the dorsal color is almost black, whereas in fusca it is seldom even 

 in the smallest specimens that they have not coalesced into a light dorsal 

 band. When these spots do coalesce in monticola portions of the dark 

 outline are left as conspicuous dark spots on the generally pale dorsal 

 band. The ventral coloration is practically uniform and lacks all trace 

 of the mottling so conspicuous in fusca. The sides are not mottled as in 

 fusca, but the dark lateral band merges gradually into the pale ventral 

 surface. In the young the ventral surface is unpigmented. A uniform 

 pigmentation gradually encroaches on the belly from the sides inwards 

 and from behind forwards, so that the last unpigmented part of the ven- 

 tral surface is between tlie fore legs. Eventually the whole belly is uni- 

 formly and lightly pigmented. In some specimens this pigmentation is 

 fairly dark, never however becoming as dark as in quadramaculata. In 

 comparing monticola with the latter it should be remembered that mon- 

 ticola usually retains traces of the dorsal pattern and never has the light 

 lateral band so characteristic of young and medium quadramaculata. 



The only sexual difference discernible in this form is the very slightly 

 more flexuous outline of the jaws in the male. 



Remarks. — This animal is between fusca and quadramaculata, with 

 which two species it has been hitherto confused. Although very closely 

 related to fusca, it does not seem to intergrade with it in the mountains 

 of Virginia and West Virginia where they occur together. So far as 

 known fusca does not occur in the mountains of North Carolina. 



Distribution. — From Clarke County, Virginia, and (Treenl)rier County, 

 West Virginia, south in the Alleghanies to Brevard, North Carolina, and 

 probably into Georgia. Zonal range. Transition and Canadian. Vertical 

 range, 500-4500 feet. 



Specimens examined. — Sixty-three, from localities as follows: North 

 Carolina: Brevard (type locality), 21; Burnsville, 1; Spruce Pine- 

 Mica ville, 1 ; Cane River, 3; B Ian tyre, 2; Sunburst, 3; Joanna Bald, 

 near Andrews, 1; Tatula Mt., near Highlands, 1. Virginia: Berry's 

 Ferry, Clarke County, 1; Hanging Rock, Clarke County, 8; Clarke 

 County, 1; Delaplane, 2; Stony Man, 1; Augusta County, 2. West Vir- 

 ginia: Greenbrier County, 2; Baileysville, 2; Star Creek, 2; Horsepen 

 Creek, 1 ; Big Stony Creek, near Barger's Spring, 1. 



Desmognathus ochrophsa carolinensis subsp. nov. 



Type from spring near top of Mt. Mitchell, North Carolina, altitude 

 "over 6500 feet"; No. 31,135, male adult, U. S. National Museum; col- 

 lected October 5, 1902, by Brimley and Sherman. 



Diagnosis. — Similar to ochrophsea, but larger, with dark belly, and 

 with a tubercle canthus oculi. Transformed specimens, 44-113 total 

 length; length of head and body, 24-54 mm.
