_Cristâ suprà cervicem elevatiore, suprà dorsum humiliore; tuberculis
verticalibus subdepressis, occipitalibus conicis; caudâ tereti._
_Amblyrynchus Demarlii._ Bibr. Hist. Rept. IV. p. 197.
This species was first described by Mons. Bibron in the “Histoire des
Reptiles,” and so fully as not to require any detailed account of its
characters here. It has not, however, hitherto been figured, and it is
thought very desirable to embrace so good an opportunity of giving a
representation of so interesting an animal. Its most important
structural peculiarities will be alluded to in the account of the next
species, which is an aquatic form, whilst the present is strictly
terrestrial. The toes are long, compared with those of the other, and so
unequal as to constitute essentially an ambulatory form.
By Mr. Darwin’s observations we are now enabled fully to confirm Mons.
Bibron’s suggestion, that this species was from the Galapagos, and to
establish the genus as strictly appertaining to that curious and
interesting locality.
