Hoplodactylus tuberculatus, sp. n. 



Head large, oviform ; snout rather longer than the distance 

 between the eye and the ear-opening, once and three-quarters the 

 diameter of the orbit; ear-opening round, half the diameter of the 

 orbit. Body and limbs moderate Toes slightly webbed at the 

 base except outer two. Digits dilated as in H. pacificus, the length 

 of the slender distal part about equal to that of the dilated portion, 

 and nearly four times the width ; about ten lamellce under the 

 fourth toe, all nearly straight. Upper surfaces: Snout covered 

 with large granular scales, the rest of the upper surfaces with 

 granular scales interrupted by numerous blunt, conical, smooth 

 tubercles, recalling those of Gymnodactylus pelagictis in size and 

 arrangement but less regularly disposed in linear series on the 

 back, twenty four such longitudinal series on the dorsal region, 

 tubercles small on head and fore-limbs, largest on back, root of 

 tail and hind-limbs. Rostral twice as broad as high, with 

 median cleft above extending nearly half way to the free edge of 

 the scale ; a pair of supranasals succeed the rostral, and are 

 separated by a small scale in the median line ; nostril pierced 

 between the rostral, first labial, supranasal, and four small scales ; 

 12 or 13 upper labials and 10 or 11 lower, including the smallest. 

 Lower Surfaces: Mental smaller than rostral, triangular; three 

 pairs of chin-shields, inner largest, outer granular scales 

 adjacent to the labials much larger ttian the minute gular 

 granules ; abdominal scales larger, flat, hexagonal ; a median 

 series of wide scales under the tail. Tail cylindrical, tapering to 

 a tine point, one fourth longer than the head and body.
