 beyond the choana?, converging l)ackward and well separated; nostril 

 much nearer the tip of snout than the eyes, their distance from the 

 eye less than the diameter of the latter; upper eyelids narrower than 

 the interorbital space; tympanum a little less than one-half the diam- 

 eter of the eye, its distance from the eye less than one-half its diam- 

 eter; fingers with rather small disks, tirst equalling second; disks of 

 toes not smaller than those of the lingers; tip of tirst toe reaching disk 

 of second; two metatarsal tubercles, the outer being rather small and 

 obscure; series of plantar tubercles corresponding to metatarsals; no 

 tarsal fold; the bent limbs being pressed along the side, knee and 

 elbow, fail to meet; hind limb being extended along the side, heel

This is the largest of eleven specimens collected by us in Vieques. 

 The largest specimen from St. Thomas described by Reinhardt and 

 Luetken measured 31 mm. in total length. This species seems there- 

 fore to be somewhat smaller than K aiirlculatus. 



Coloration of living HpeGiinenn. — The larger specimens collected by 

 us in Vieques were pale gra}?^ with scarcely any dusky marking except 

 a dark streak from nostrils, through eye, over and behind the tym- 

 panum, a few dark mottlings on the posterior concealed part of the 

 thigh, and a dusky longitudinal line on inner side of tibia and tarsus. 

 The smaller specimens were of a uniform dull grayish brown above 

 with regular longitudinal dusky markings. 



llnbltat. — This species seems to be contined to Vieques and St. 

 Thomas and is apparently not common. Its occurrence on St. John 

 and St. Croix is somewhat doubtful, according to Reinhardt and 

 Luetken. It was not found by the U. S. Fish Commission parties in 

 Vieques during their visit in 1899, but a young specimen from this 

 island is in the Zoological Museum in Copenhagen.
