I ai»i»eu«l a description of tiio typo speeiinen of tlie Ibjla Hcbuhna 

 llallowell (U. S. Pae. 11. It. Survey Kept., 35th parallel, Heptiles p. 21), 

 which I afterwards called JI, cadaccrina, owluff to the preoccupation of 

 Ilallowell's name. The single specimen known is now in bad condition, 

 and I um not sure that it should not bo referred to the //. rciiilla. The 

 descrii)tion now {(iven was taken from the specimen when nearly fresh. 



Size medium ; form stout; legs elongate ; head short, broad, breadth 

 less than three times in the total length ; muxzle rounded, little promi- 

 nent; canthus rostralis straight, elevated; lingers free; toes two thirds 

 webbed; the digits short, stout; the pallettes large ; a strong tarsal 

 wing or fold; eyes small ; skin smooth. 



Femora unicolor behind; no dark labial border or dark or light lat- 

 eral stripes; color j>ale, with indistiiuit blackish dorsal spots. 



Tiio heel of the extendetl hind limb extends to between tlie orbit and 

 the end of the mn/./Ie; the largest digital dilatations e(pjal the tym- 

 panum, which is indistinct and cue-fourth the size of the eye. The eye 

 is smaller and less prominent than usual, its long diameter measuring 

 the width betwten canthus rostralis at orbits, one and one-third times, 

 and two thirds length of the brachium. Tool oiu^ aiul three-fourths and 

 one and live-sixths breadth of head at canthus oris ; vomeriiu'/ teeth 

 entirely between the luires, which appear larger than the ostia of the 

 Eustachian tubes. 



Sacral diai»opliyses elongate; triangles very narrow proximally; 

 upper surface slightly convex, thus ditfering from the eximia, where they 

 are broader, Halter, and not so produced. Skin nearly smooth above; 

 abdominal areolatioiis not extending on the sides; a pectoral fold. Toes 

 stout, niargineil ; the dilatations large (not proportionally to the digits), 

 except on tiu' thumb. 



Above gray, with an iuterocular and numerous dorsal irregular black- 

 ish spots. Cantiius rostralis and band behiiul eye dark shaded; lij) an«l 

 prebrachial region light, dark punctulate. Limbs indistinctly cross- 

 barred ; below yellowish, immaculate.
