orbital. Females from Pebas, with eggs, have scattered white spots 

 on lower surface of body very pronounced, though the postorbital 

 flange is hardly developed. 



Bufo cseruleocellatus sp. nov. PI. V, upper figure. 



Body depressed, its width about equals that of head. No 

 bony ridges on head,. which is broadly depressed, though not con- 

 stricted from rest of body. Snout a httle depressed, contour as 

 viewed above little less than right angle. Eye large, though some- 

 what less than snout in length. Mouth large, rictus extending 

 slightly beyond eye. Lips thin, skin firm, and jaw edges trenchant. 

 No teeth. Tongue large, free for great portion posteriorly, and hind 

 edge triangular. Internal nares moderate. External nares well 

 separated, so that each would fall in external fourth of antero- 

 interorbital width. Latter depressed, or very slightly convex. 

 Lores a little concave, smooth. Tympanum small, vertically 

 elHpsoid, and vertical diameter about f horizontal length of eye. 

 Parotids large, well separated from eyes, though each equals about 

 If eye lengths. Along upper side of head from snout tip low fold 

 extends back, including upper eyelid externally and outer edge of 

 parotid. Fold on latter well marked, though not extending on costal 

 region. 



Skin largely smooth, though upper surfaces of limbs and hind pelvic 

 region above, with weak tubercles, a few of which are less developed 

 on lower surfaces of hind limbs and costal regions. Parotids and 

 eyebrows more or less granular. Lower surface of body otherwise 

 smooth . 



Limbs all rather slender. Fingers not webbed, second longest, 

 and first and third subequally shortest. Finger tips all with rather 

 well-developed tubercles. Toes webbed rather narrowly at bases, 

 and each with somewhat well-developed distal tubercles. Two equal 

 well-developed metatarsal tubercles. Fold of skin along outer tarsal 

 edge. 



Color in alcohol dark slaty-gray above, ground-color nearly uni- 

 form, marked with a number of scattered more or less rounded dusky 

 to blackish blotches, each indistinctly edged with gray, or paler tint 

 than general body-color, to form obscure ocelli. Upper surfaces of 

 these limbs also marked with similar blotches, as three or four on 

 each joint. Lower surface of body pale gray, evidently translucent 

 in life. Breast and throat all more or less clouded with slaty specks, 

 or obscurely spotted with paler or more whitish tints. 

 Length 23 mm.
