Bufo punctatus, Camp (1916a, pp. 509, 512). Description of larva; habits. 
Bufo punctatus, Grinnell and Camp (1917, p. 144, fig. 4). Range in Cali- 
fornia. 
Bufo punctatus, Stejneger and Barbour (1917, p. 29; 1923, p. 26). General 
range. 
Diagnosis. — Size small, smallest Bufo in California, head-and-body 
length less than 75 millimeters (3 inches) ; parotoid glands short, 
rounded, placed low on shoulder region ; cranial crests inconspicuous 
or lacking ; eyes widely separated ; warts very small, low and scattered, 
red-tipped in life. 
Comparisons. — Distinguished from other California Salientia ex- 
cept Bufonidae by presence of small but distinct parotoid gland on 
shoulder region; from other California Bufonidae in general by very 
small low warts; from Bufo alvarius by small size, straight instead of 
curved cranial crests, and presence of reddish tips on warts. 
Description. — General size small ; head and body depressed ; limbs 
relatively slender; whole head including muzzle flat-surfaced above; 
head truncately triangular as viewed from above, thin in profile ; tip 
of muzzle at nares overhanging lower jaw; canthus rostralis dis- 
tinct; external nares opening dorsolaterally below canthus rostralis; 
side of head below canthus and orbit steep ; orbit large, its length 
nearly one-half length of head, margin of orbit projecting slightly 
beyond jaw; eyes widely separated, interorbital space about two-thirds 
length of orbit ; cranial crests small, varying from slight lines of gran- 
ules to distinct low ridges, but scarcely in evidence on living animal ; 
each crest composed of straight longitudinal ridge along inner border 
of orbit joined to short transverse ridge extending between orbit and 
parotoid gland to above tympanum; tympanic membrane 0 A 7 al or 
nearly round, vertical diameter about one-half length of orbit; paro- 
toid gland short, rounded or triangular in outline, of moderate height 
and smooth-surfaced, anterior border over middle of tympanic mem- 
brane; upper arm not deeply embedded in skin of body; forearm 
nearly equal to hand in length ; two metacarpal tubercles, one opposite 
fourth finger, the other opposite first; numerous smaller tubercles on 
plantar surface of digits; digits slender except first, in order of 
decreasing length, 3, 1, 4, 2 ; dorsal surface of body evenly rounded ; 
more than half of femur free from skin of body ; femur usually 
slightly longer than tibia ; tarsus about two-thirds length of tibia ; foot 
slender ; two small metatarsal tubercles opposite first and fifth toes ; 
toes in order of decreasing length, 4, 3, 5, 2, 1 ; web deeply incised, 
only half of the one (basal) phalanx of fourth toe included; outline 
of lower jaw acutely oval. 
Tongue narrow, less than half width of mouth at angles of jaws, 
oval in outline, attached along anterior two-thirds; internal nares 
large, placed far forward in mouth. 
Labial region with enlarged warts; eyelids warty, interorbital 
region smooth; tympanic membrane smooth; parotoid glands covered 
with papillae ; warts on dorsal and lateral surfaces of body small, low, 
and scattered ; warts on lateral surface of head below tympanic mem- 
brane and on exposed surfaces of limbs more closely spaced than on 
body.
