In a revision of the North American Tailed Batoachia, published hi the Journal of the Academy of Natural Sciences, 2d series, voh i,, p. 281/ ( 1849*) we intimated a doubt a* to whether j$ Hre< jkn or ^ the axolotls were adult apimals. Their wonderful resemblance to the larvae of Amby$ tama punctate was our. chief ground for thia Velief. Since then, however, we have seen the description and figures by Sir JSyerard Home of & mexicanu^ m which he clearly indicates, in one individual at least, ovaries distended with eggs*.

This species, one of the most elegant of its genua, is the third hitherto described as found in the United States, for we have no doubt that the lisard referred to in Long's expedition, under the nartie ofAmeiva Us* elata> will come under this genus, and be closely allied to our. species. Ko specimen of this being extant at the present time in any known collection, a direct comparison with the other species of QnemidopkorU* was nofcjtossible* That A. tMelata, however, although closely allied to, is not identical with our species, we think that any one will be convinced on comparing Say's do* scription with the figures in pi.

The plates of the head above ( fig. 8), below ( fig. 2), and on the sides ( fig. 1), need no further description. The minute scale* of the back and upper portion of the legs contrast strikingly ' with the eight rows of large scales of the beHy and those of the lower part of the hind' legs, as well as with those of the inferior surface of the head and throat On the tail again, the scales assume; another character, well- opposed too; they are longer than |
