CHITON. 
Puate XIII. 
Species 68. (Mus. Cuming.) 
Curron Quoi. Chit. testé oblongd, valvis undique tenuis- 
simé et creberrimé liratis, umbonibus subprominulis, 
levibus ; aut viridi, aut nigricante-olivaced, aut rubidé ; 
ligamento granoso-coriaceo. 
Quoy’s Curron. Shell oblong, valves very finely and 
closely ridged throughout, umboes rather prominent, 
smooth; green, or blackish olive, or dull coppery 
red; ligament granosely coriaceous.

Chiton viridis, Quoy. 
Hab. New Zealand. 
The colour of this species appears to be of one uniform 
tint, without any indication of pattern, varying from green 
to dull red. 
It has been dedicated to the zealous naturalist of the 
ship ‘Astrolabe’ by M. Deshayes in consequence of the 
name viridis given to it by M. Quoy having already oc- 
cured in Chemnitz, Conch. Cab. vol. viii. pl. 94. f. 794. 
(not vol. x. pl. 178. f. 1689.) ; this is scarcely allowable, 
however, as the word is only used in the diagnose, not as 
a specific name, “ Chiton extus viridis intus candidus’’, a 
variety probably of the C. Chiloensis. 
Species 69. (Mus. Cuming.) 
CHITON PUNCTICULATUS. Chit. testdé oblongd, anticé sub- 
attenuata, valvis subrotundatis, levibus aut concentricé 
striatis, peculiariter puncticulatis, presertim ad latera, 
puneticulis wregularibus ; subdistantibus, albidd, san- 
guineo lauté undatd, ad latera fusca, interdum omnino 
nigra ; ligamento corneo. 
THE FINELY PUNCTURED CuIToNn. Shell oblong, a little 
attenuated anteriorly, valves somewhat rounded, 
smooth or concentrically striated, peculiarly punc- 
tured, especially at the sides, punctures irregular, 
somewhat distant; whitish, showily waved with 
blood-red, brown at the sides, sometimes entirely 
black; ligament horny. 
Hab. P 
Tt will be seen by the examples of this species figured 
how much it varies in colour; the punctured character 
which I have selected to distinguish it is constant, though 
generally more or less obscured by erosion. 
Species 70. (Mus. Cuming.) 
CHITON PICEUS. Chit. testd ovatd, crassiusculd, valvis con- 
centricé planiliratis, lirarum interstitis elevato-striatis 
et interdum granatis, umbonibus subrostratis ; piceo- 
nigra, virescente utrinque summitatem wmbonalem ; 
ligamento corneo, processibus brevibus calcareis sete- 
formibus albidis profuse obsito. 
THE prtcH Curton. Shell ovate, rather thick, valves 
concentrically flatly ridged, interstices between the 
ridges elevately striated and sometimes grained, 
umboes a little beaked ; pitch black, greenish on each 
side the umbonal summit ; ligament horny, profusely 
beset with whitish short calcareous bristle-like pro- 
cesses. 
GMELIN, Syst. Nat. p. 3204. 
Hab. New Holland (on the rocks) ; Cunningham. 
This I believe to be the true C. piceus; it is a thick 
ponderous, shell, of which the ligament when in a good 
state of preservation, is covered with calcareous bristle-like 
processes as in C. spiniger, but much finer. 
Species 71. (Mus. Cuming.) 
CHITON FULGETRUM. Chit. testd ovatd, anticé subattenuatd, 
undique, sub lente, minutissime et creberrimé decussatin 
puncturatd, valvis terminalibus ceterarum areisque 
lateralibus subobscuré radiatim sulcatis ; rubido-fusca, 
undulis luteis nigrisque longitudinalibus peculiariter 
picté ; ligamento-corneo. 
THE LIGHTENING CHITON. Shell ovate, a little attenuated 
anteriorly, very minutely and closely decussately 
punctured, under the lens, throughout, terminal 
valves and lateral areas of the rest somewhat ob- 
scurely radiately grooved ; reddish-brown, peculiarly 
painted with longitudinal yellow and black zigzag 
waves ; ligament horny. 
Hab. ? 
This species, it will be observed, is distinguished by a 
very peculiar style of painting, which in the absence of 
sculpture, may be regarded of specific importance. 
Species 72. (Mus. Cuming.) 
CHITON LINTER. Chit. testd oblongd, anticé subattenuatd, 
valvis medio tumidis, undique levibus, aut minutissimée
