18. PHBY^OBATEACnrs aueitus, sp. n. (Plate XXVIII. fig. 2.) 

 Tongue with a free conical papilla in the middle. Habit slender. 



Head moderate, as long as broad ; snout pointed, projecting beyond 

 the mouth, with angular canthus and nearly vertical loreal region ; 

 nostril equally distant from the eye and the end of the snout ; 

 interorbital space narrower than the upper eyelid; tympanum 

 distinct, measuring nearly half the diameter of the eye. First 

 finger as long as second ; toes two-thirds webbed ; tips of fingers 

 and toes dilated into small disks ; subarticular tubercles small ; two 

 small metatarsal tubercles ; a very small tubercle not far from the 

 latter, on the inner side of the tarsus. The tibio-tarsal articulation 

 reaches the tip of the snout. Skin smooth, or with very small 

 warts above ; a narrow glandular fold on each side of the back 

 from the eyes to the sacral region, the two folds converging on the 

 scapular region ; a similar fold from the eye to the shoulder. 

 Greyish or reddish brown above, darker on the middle of the back, 

 with or without a filiform light vertebral line, which is continued 

 along the middle of the upper surface of the thigh and the inner 

 side of the leg ; glandular folds edged with blackish ; a few round 

 black spots may be present on the pelvic region ; limbs with rather 

 indistinct darker cross-bars ; hinder side of thighs blackish brown, 

 edged with whitish above near the vent ; inner side of legs 

 also blackish brown ; lower parts white, with small brownish spots 

 on the throat and breast in the female ; the throat blackish in the 

 male. Male with an internal subgular vocal sac. 



From snout to vent 37 millim. 



Three specimens from the Benito Eiver (G. L. Bates). 



The distinct tympanum distinguishes this species from P./jlicalus 

 Gthr., to which it bears some resemblance.
