REPORT OF THE DIRECTOR 1923 93 
The sides of the body and tail and the legs above are rather uni- 
formly mottled with pigment, the interspaces being dull yellow. The 
lower half of the sides in some specimens, however, is more strongly 
pigmented and in strong contrast with the immaculate venter. The 
tail above, particularly the distal half, is slightly keeled as in larvae 
of D. fuscus. Thereare no striking differences in the body pro- 
portions of the larvae of this species and of D. fuscus but the 
head seems to be somewhat broader in the latter. Where the ranges 
of the two species overlap, it may be impossible to separate the 
young larvae except by the amount of the gill reduction for a given 
size. In the larvae here considered the gills are reduced to short 
stubs which are pigmented and bear two or three unpigmented 
terminal filaments. 
Desmognathus phoca (Matthes) 
Grandfather mountain, October 11th-12th, (4000 feet) ten; 
Swannanoa Gap October 14th, three; Montreat, October 16th, 
seven; Stoney mountain, October 18th, seven; Mount Pisgah, 
October 18th, one. 
Several examples of this species strongly resemble, superficially, 
Leurognathus marmorata Moore. They have the 
same light buff ground color on the back and these light areas are 
more or less separated by darker pigment. The difference in pattern 
lies in the greater development, in Leurognathus, of the dark 
pigmented areas which are disposed in rather large blotches alter- 
nating with the buff patches; in D. phoca the dark pigment 
rather narrowly surrounds the light areas as indicated in Dunn’s 
figure }. 
Old and dark individuals are rather hard to distinguish from 
certain specimens of D. quadra-maculatus, especially when 
the dorsal pattern has been obliterated and the venter becomes well 
pigmented. 
Desmognathus quadra—maculatus (Holbrook) 
Grandfather mountain (southwest side) October 11th—12th, 
(4000 feet) ninety; at 4500 feet, five larvae; Mount Mitchell, 
October 21st, (4500 feet) ten; at Camp Alice (6000 feet) five; 
Montreat, October 16th, eleven; Stoney mountain, October 18th, 
six; Swannanoa Gap, October 14th, five. 
Any stone or stranded log in the mountain streams may furnish a 
hiding place for one or more specimens of this salamander. They
