Description. — Adult female, USNM 96942 (cotype of Leptodadylus 

 trivittatus), Montserrat, Campo Bello, Rio de Janeiro. Vomerine 

 teeth in two long, very heavy, transverse, narrowly separated rows 

 far behind the choanae; tongue a little more than half as wide as 

 mouth-opening, oval, not indented on its free posterior margin; 

 snout blunt, short and broadly rounded when seen from above, trun- 

 cate and sloping slightly forwards to the lip border in profile, the 

 upper jaw consequently not projecting beyond the lower; nostrils 

 more lateral than superior, projecting, their distance from end of 

 snout less than one-half that to eye, separated from each other by 

 an interval equal to their distance from eye. Canthus rostralis very 

 blunt, the loreal region slightly concave and slanting outwards con- 

 siderably towards the upper lip border. Eye large and prominent, 

 its diameter only slightly greater than its distance from nostril; 

 interorbital diameter 1% times the width of the rather narrow upper 

 eyelid, about equal to distance between nostrils. Tympanum small 

 but distinct, one-half the width of eye, separated from eye by an 

 interval nearlj'- as great as its own diameter. Fingers free, not fringed, 

 their tips scarcely dilated, not grooved above, second and fourth 

 subequal, reaching slightly beyond the base of penultimate phalanx 

 of third; no pronounced pollex, but subarticular and palmar tubercles 

 well developed; toes without webs or fringes, all their disks except 

 the fu'st one distinctly larger than those of the fingers, not grooved 

 above and with the terminal bones decidedly T-shaped; third toe 

 much longer than fifth, reaching well beyond the base of antepenulti- 

 mate phalanx of fom'th; a prominent blunt-edged inner and a smaU 

 wartlike outer metatarsal tubercle; a distinct inner tarsal ridge emanat- 

 ing from base of inner tubercle and extending nearly to heel; body 

 moderately slender, in postaxillary region slightly less than greatest 

 width of head; when hind leg is adpressed, heel reaches to posterior 

 corner of eye; when limbs are laid along the sides, knee and elbow 

 barely touch; when hind legs are bent at right angles to body, heels 

 considerably overlap. Skin of upper parts thick and smooth, appear- 

 ing minutely glandular under microscope; no prominent supratym-
