50 BARBOUR — SOUTH AMERICAN VERTEBRATES eee: 
Diploglossus resplendens sp. nov. 
Plate 4. 
Type,— a single example, no. 7286, Museum of Comparative Zodlogy, 
from the junction of the Kaka and Beni Rivers, tropical eastern Bolivia; 
Frank J. Dunleavy, collector. 
This species belongs to the genus in which it is placed, in its restricted 
sense. The digits terminating in a large compressed sheath, into which 
the claw may be retracted, distinguish it at once from a Celestus, in which 
genus the ungual sheath is wanting. 
Lateral teeth simple, recurved, with rather obtuse crowns. Head de- 
pressed; not distinct from neck; snout short; canthus rostralis rather 
rounded; ear opening easily visible, roundish in outline; three praefrontals, 
azygos a little smaller, broader than long, separated from the frontal; 
frontal nearly twice as long as broad; parietal on each side separated 
from the frontal and supraoculars by two shields; nasal separated from 
the rostral; two postnasals; rostral somewhat. broader than the mental; 
the suture between the sixth and seventh supralabial falls below the centre 
of the eye; four chin shields on each side, of which only the anterior is in 
contact with the infralabials. Body somewhat squarish in cross section, 
but depressed. Forty-four rows of striate scales around the middle of the 
body. The adpressed limbs do not meet. Digits not markedly shortened, 
slender. Tail cylindrical, longer than head and body. 
Color very striking. Upper surfaces black, the back with nine white 
cross-bars, the tail, with eight. Of these, the distal three show a suffusion 
of yellow and pink. The ninth band on the body runs out onto the thighs. 
Lower surfaces of body rosy to deep pink; a fine red spot in the middle of 
each black band on the ventral surface of the tail. Limbs, laterally, gray- 
ish to brownish. 
This beautiful lizard is most nearly related to D. fasciatus (Gray) 
from Brazil. It is strikingly different in many respects, however, 
and its discovery has greatly increased the hitherto recorded range 
of the genus.
