THE HERPETOLOGY OF HISPANIOLA 71 



of the tympanum; fingers not webbed, the first slightly shorter than 

 second, which is equal to fourth; toes very slightly webbed at the base, 

 third scarcely longer than fifth; subarticular tubercles well developed; 

 small tubercles on sole of foot; two metatarsal tubercles, the inner 

 small and oval, the outer a little larger and round; an indistinct tarsal 

 fold; heels just touching when hind limbs are folded at right angles to 

 axis of body; hindlegs short, the tibiotarsal articulation barely reaching 

 to posterior border of tympanum when legs are adpressed ; skin of back 

 smooth except for a few elongate glandular ridges on the lumbar 

 region; a narrow glandular fold originating behind the eye, continuing 

 over the tympanum and along the dorsolateral region where it becomes 

 very indistinct; skin of chin and chest smooth, that of belly and 

 posterior femur finely granular; a median depressed area on belly, 

 with a shallow groove leading from it to each arm insertion, and a 

 very heavy lateral disk around it. Apparently no external vocal sac. 



Dimensions: Head and body, 21 mm.; head length, 7.5 mm.; head 

 width, 8 mm.; foreleg from axilla, 13 mm.; hindleg from vent, 26.5 

 mm.; tibia, 8 mm. 



Color (in alcohol): Dorsal surface drab, with an indistinct, darker 

 shield-shaped mark on occiput, followed by a faint chevron-shaped mark 

 between the shoulders; a wide dark line from the posterior corner of 

 the eye over the tympanum slanting obliquely back and ending at the 

 shoulder; sides below the dorsolateral region dark sepia; an irregular 

 dark crescent from above the groin to side of coccyx, merging with 

 the dark triangular postanal patch, of which the outer posterior angle 

 covers the posterior and lower surface of the femur, which is otherwise 

 wood brown above with a few small dark spots; arm, tibia, and foot 

 with irregular dark cross bars; ventral surfaces olive-buff clouded with 

 minute darker dots; edge of lower lip with small brown spots; knee and 

 lower side of tarsus dark sepia; palms of hands and lower side of fingers 

 and toes pale olive buff. 



Variations. — The type is the largest specimen of the examples at 

 hand. The hindleg is 114 to 137 percent of the total length in the 

 four adult topoparatypes, while the length of the tibia is between 35 

 and 43 percent of the total length. Including the type, the average 

 for these two relative measurements is 124.4 and 38.4 percent. 



The seven adult paratypes from Valle Nuevo have the hindleg 

 between 117 and 127 percent of the total length, averaging 122 per- 

 cent: the tibia is 36 to 43 percent, averaging 40 percent. 



A good deal of variation in color pattern is to be seen, as in the Loma 

 Rucilla paratypes two of the immature ones show a very distinct light 

 dorsal line bordered with dark sepia; another is pale olive above, with 

 scarcely a trace of the dark supratemporal or lateral markings; 

 another has clay-colored legs against which the dark oblique cross 

 bars and postanal patch stand out prominently. The belly in one or
