The proportions are, however, much those of the G. microstomiis at the same age. This, with the large number of costal grooves, renders it almost certain that the full-grown individuals are much like those of the latter species, and very probably of near the same size. Skin everywhere quite smooth; no traces of pores on the head or paro- toid region in many siDecimens. Costal folds fourteen, distinct; head folds slighth' marked, the gular slight. A median dorsal groove. Head oval, rather flattened and broad; canthus rostralis somewhat marked. Mouth large; canthus behind eye, anterior canthus of latter marking middle of margin. Nostril a little nearer eye-fissure than length of latter, probably equal in older specimens. AVidth between anterior canthus of eye double length of fissure; external separated by one length of same, which is less than the distance between inner nares. Tongue small, as in other young, but not fissured or grooved, as in those of the two preceding species. Palatine teeth forming an arched series between nares, extending to their anterior border, and not beyond their inner border in the lateral direction. From their resemlance to those of A. microstomum of the same age I suspect they are similar in old individuals. Body rather slender; width of head at jaws four times in total length to groin, and .75 length to gular fold. Tail short, longer when older, equal from its basis to axilla. Limbs moderately stout; digits elongate; third and f
