T h e genus which I take the present favourable opportunity to illustrate, formed
a section or sub-genus of the genus Tropidurus, according to Weigmann, who, however,
was acquainted with two species only ; B r . Chilensis and P r . nigromaculatus.
O f the varieties of the former of these, that author has made no less than three
species ; hut these have been very properly reduced by M. Bibron to one onlyL
The last-named excellent erpetologist described several additional species,
which had been brought from Chile, by M. D ’Orbigny, and others ; and I received,
some years since, from Capt. King, three or four species w'hich were found
by him in the same locality, in the course of his well-known survey. The number
of species altogether, hitherto known, amounts to ten ; to which I have now the
opportunity of adding four entirely new, forming part of the interesting collection
of R cptilia made by Mr. Darwin. One of them, P r . Kingii, was already in my
collection, amongst those which were given me by Capt. King. The genus,
therefore, of which, but lately, two species only were known, now consists of
fourteen ; and it is liighly probable th a t more may yet be obtained by more prolonged
and extensive investigation in the same districts.
