upper lip. Eye large, prominent, its diameter IK times its distance 

 from nostril, a little less than its distance from end of snout; inter- 

 orbital diameter equal to width of upper eyelid, equal to distance 

 between nostrUs. Tympanum not visible. Fingers moderately 

 long, free, with distinct lateral ridges, their tips ending in ball-shaped 

 disks which are not enlarged; second and fourth subequal, reaching 

 to base of penultimate phalanx of third; a slight elongate wartlike 

 rudiment of a pollex, and two larger palmar tubercles; toes webbed 

 only at the base, with fringes along their sides, their tips also rounded 

 but not wider than the preceding phalanx, third longer than fifth, 

 reaching halfway to base of penultimate phalanx of fourth; a promi- 

 nent elongate inner and a very small round outer metatarsal tubercle ; 

 subarticular tubercles on feet and hands very well developed; a faint 

 inner tarsal ridge. Body broadly elliptical in shape, in postaxillary 

 region a little narrower than the head. When hind leg is adpressed, 

 heel reaches slightly beyond tip of snout; when limbs are laid along 

 the sides, knee and elbow overlap considerably; when hind legs are 

 bent at right angles to body, heels meet. Skin of upper parts heavily 

 tuberculated, with elongate glandular ridges prominent between the 

 shoulders and on the back; a slight dermal ridge from posterior corner 

 of eye to angle of mouth ; a large round inguinal gland in the groin in 

 the male; ventral surface minutely pitted with glandules, but not 

 granular except around the anus. No skinfold across chest or belly, 

 and apparently no external vocal sac in the male. 



Dimensions. — Head and body length 35 mm.; head length 15 mm., 

 width 15.5 mm.; femur 17 mm.; tibia 18.5 mm.; foot 17 mm.; hand 

 9.5 mm. 



Color in alcohol. — Dorsum light wood brown, with a lighter band 

 between the eyes, followed by a darker triangle; an indistinct reticu- 

 lation of sepia outlining the heavy dorsal glandular ridges ; femur and 

 tibia with two wide, dark, diagonal bars; venter cream color, with a 

 sprinkling of very fine tawny dots on the chin. Posterior femur 

 cream color with indistinct tawny reticulations. 



Remarks. — This species is very common in the biological reserve 

 at Alto da Serra, living among rock piles along the mountain streams. 

 Some from this place were sent to H. W. Parker, British Museum 

 (Natural History), who wrote on June 7, 1937 that they "agree with 

 our specimens from the same locality and with a cotype of C. duseni 

 Andersson. I believe this is neither more nor less than C. asper 

 Werner, so that duseni and semipalmatus should be regarded as 

 synonyms. This, I believe, was Lutz' view." Barbour (1925, p. 8) 

 regarded semipalmatus as umhrinus, after comparing it with the 

 type of the latter.
