longer than femur; hind foot about three-fourths length of body; 
tarsus about two-fifths length of foot; one low inconspicuous meta- 
tarsal tubercle at base of innermost toe ; toes slender except outermost, 
which is broad and flat ; toes, in order of decreasing length, 4, 3, 5, 2, 
1 ; webs very short, reaching about to end of innermost phalanx on 
fourth toe, but a narrow edging of web on side of each toe. 
Tongue broad, practically filling mouth, closely margining lower 
jaw anteriorly, truncate behind,' broadly attached for anterior two- 
thirds to floor of mouth ; internal nares small, widely separated, well 
back from tip of nose, opposite anterior border of orbit; vomerine 
teeth in two small separate rounded patches between nares. 
Surfaces of body everywhere smooth, with few low granular 
papillae on dorsal surface of body; plantar surfaces of palms and 
soles smooth. 
General coloration (in alcohol) above, dark gray ; triangular patch 
covering posterior half of each eyelid and posterior part of interorbital 
region, blackish; forepart of head above, pale gray; spot below nostril 
on each side of snout, stripe behind eye, bar on fore limb, and several 
rows of small spots on back, blackish; exposed surfaces of limbs 
specked with dusky ; ventral surface of body light grayish anteriorly, 
yellowish posteriorly. 
Gaige (1920, pp. 4-5) gives the following color descriptions of the 
living animals as seen in Washington. 
Female : back cacao brown, light spot on head pinkish cinnamon, warts on sides 
and legs cinnamon buff, sides of head and body dark olive buff, below flesh color 
which was most distinct on chin and legs, belly densely spotted with mustard 
yellow. A live male differed from the female in having a citrine drab back and 
the warts cacao browui ; the ‘ ‘ tail ’ ’ above was the color of the body with a dark 
stripe down either side, beneath darker. The ground color is most commonly old 
rose or brick red, but it may vary from cream white, through various shades of 
pink, gray, and brown to almost black. In the lightest and darkest specimens the 
pattern is fairly well obscured. The glandular ridge or row r of glandules on the 
side is usually dark tipped with golden yellow ; the dark spot on the head is almost 
triangular; the dark line on the wrist is seldom interrupted; the upper surface 
of the limbs is often set off from the lower by a dark line which merges gradually 
into the color beneath. The females are usually more brightly colored than the 
males. 
Description of larva. — Head-ancl-body 18 mm. ; tail 22 mm. ; body 
slightly wider than high; external naris protruding, nearer to orbit 
than tip of snout, aperture lateral; eyes small, well up on dorsal 
surface of head, interorbital space 3.5 mm. ; spiraeulum ventral, a 
transverse slit about midway of head-and-body length ; anus median, 
concealed by a ventral flap of skin; tail fin moderate, dorsal part 
evidently originating close to upper base of tail ; mouth region concave, 
8 mm. wide, 7.5 mm. in opposite (anteroposterior) dimension; upper 
lip (beak) a nearly straight transverse band of black about 6 mm. 
long ; lower lip minute, concealed beneath upper ; labial teeth in s / 10 
rows, occupying entire wddth of mouth region, first ‘row’ multiple, 
of several rows of minute teeth, second and third rows double, fourth 
row (just below mouth) interrupted at midline, sometimes doubled,
