Eyes larg^i; contained three times in chord of ui^ier jaw aiitl one diameter from the tip. Tympanum small (females only seen), about three-fourth the size of the eye; behind not reaching the end of the jaw. Patches of vomerine teeth very small, circular, approximated, and situated on a level with the centers of the inner nares. These arc large, oblong, and widely separated. Tongue rather small, narrow. Eustachian ostia large. The skin is moderately smooth, but on very close examiiuition is seen minutely and closely dotted all over with small pits, and among theso on the under surfaces are scattered small glandiform elevations, whicli on being emptied are represented by the pits. This is sometimes seen in other species, but seldom so distinctly, and may be caused by some pe- culiar and temporary condition of the skin. There appears to be a very low and scarcely distinct dermal ridge from the eye along the sides, but none intermediate. The granulation on the buttocks is very low ami indistinct. The fore-arm is shorter than the hand; the femur is not (piite half the length of the bodj', aiul is about as long as the tibia. The hind feet are unusually long, considerably exceeding the tibia. The feet are veiy fully webbed, coming near li, catcsbiana in this respect, the web extend- ing between the tips of the toes, slightly excavated in the inner e<lges of the second and third. The terminal joint of longest toe appears to be entirely free and the second is rather narrowly margined. In alcohol the color everywhere above and on sides (even over tyni- pauum and on buttocks) is dark purplish-br
