General color above and below, blackish brown ; broad dorsal band 
from snout to base of tail lighter brown, edged with black ; lower sur- 
face sprinkled with small whitish dots, larger on chin, gular region 
and sides. 
Measurements (of type, from Van Denburgh, loc. cit.). — Total 
length 117 millimeters; tail (from anterior border of anus), 58; snout 
to gular fold 11 ; greatest width of head 7.5 ; snout to orbit 3 ; foreleg 
9 ; axilla to groin 30 ; hind leg 10.5 ; hind foot 5. 
Range. — Plethodon elongatus is known from four specimens . col- 
lected at Requa, Del Norte County, May 22 to 26, 1911. 
Life-history. — Van Denburgh (loc. cit.) mentions a young indi- 
vidual 42 millimeters in length, collected as above. This compares in 
size with the length attained by other west coast Plethodonts at about 
one year of age and suggests a summer breeding period for elongatus. 
This specimen (in alcohol) had the dorsal light stripe bright pink, 
clouded on the head and mid-dorsal line with dark brown.

Diagnosis. — Size moderate among California salamanders, total 
length up to 133 millimeters (5^4 inches) ; naso-labial groove present; 
costal folds 10 ; maxillary and mandibular teeth inconspicuous ; body 
coloration dark reddish brown, with scattered rounded spots, of vary- 
ing size, of yellow. 
Comparisons. — Distinguished from other California salamanders 
except Plethodontidae by presence of naso-labial groove and para- 
sphenoid teeth ; from Batrachoseps by development of 5 digits on 
hind foot, 10 instead of 15 or more costal folds, stouter form of body 
and spotted pattern of coloration ; from Aneides by less swollen tem- 
poral region, smaller maxillary teeth, 10 instead of 12 costal folds, and 
presence of spots more than 1.0 mm. in diameter in coloration; from 
Hydromantes by 10 instead of 12 costal folds, less flattened head, 
smaller maxillary teeth, unwebbed digits and yellow instead of gray 
markings ; from Ensatina eschscholtzii by spotted pattern of color- 
ation. 
Description. — Form stout among California Plethodontidae, limbs 
well developed, tail moderate; head truncate oval in outline from 
above; muzzle thick in profile, rounded at end, scarcely overhanging 
lower jaw; external nares terminal, opening laterally; sides of muzzle 
slanting, no distinct canthus rostralis; orbit large, nearly equaling
