CHITON.—Prats XIX. 
‘Species 122. (Mus. Cuming.) 
Cuiton Rissor. Chit. testd ovatd, valvis terminalibus 
ceterarum areisque lateralibus tenué granoso-striatis, 
obscure concentricé corrugatis, centralibus creberrimée 
striolatis ; cinered; saturatioré variegati'; ligamento 
minutissime granuloso-coriaceo. 
Risso’s Curron. Shell ovate, terminal valves and lateral 
areas of the rest finely granosely striated, obscurely 
concentrically wrinkled, central areas very closely 
striated; ash colour, variegated with darker ash; 
ligament very minutely granosely coriaceous.

Hab. Mediterranean. Coast of Sicily; Philippi. 
The specimen here figured has rather a gigantic appear- 
ance from the circumstance of its being unusually large, 
and further magnified to the scale of the species which 
accompany it. 
Species 123. (Mus. Cuming.) 
Curron ADELAIDENSIS. Chit. testd subabbreviato-ovatd, 
undique, sub lente, minutissime reticulata, valvis termi- 
nalibus ceterarum areisque lateralibus tenuiliratis, liris 
undulatis, centralibus levibus, areis lateralibus non 
elevatis; livido-olivaced lutedque, medio fusco flam- 
mata, valvarum marginibus posticis fusco articulatis ; 
ligamento granato-coriaceo, granis peramplis. 
Tue ADELAIDE CuiTon. Shell somewhat shortly ovate, 
yery minutely reticulated throughout, under the lens, 
terminal valves and lateral areas of the rest finely 
ridged, ridges waved, central areas smooth, lateral areas 
not raised ; livid olive and yellow, flamed with brown 
in the middle, posterior edges of the valves arti- 
culatedwith brown; ligament granately coriaceous, 
erains very large. 
Hab. Port Adelaide, New Holland; Harvey. 
A very characteristic species which there is no fear of 
confounding with any other. 
Species 124. (Mus. Cuming.) 
CHITON cILIATUS. Chit. testd oblongo-ovatd, valved anticd 
terminali radiatim octo-liratd, ‘interstitiis undatim 
granoso-striatis, parvd, retusa, areis lateralibus anticé 
uniliratis, decussatim granoso-striatis, centralibus longi- 
tudinaliter granoso-striatis, granis undique obtusis ; 
cinereo-viridi, medio lutescente sparsim tincté; liga- 
mento corneo, setis perpaucis obsito. 
THE CILIATED CuHIToN. Shell oblong ovate, anterior 
terminal valve radiately eight-ridged, interstices un- 
dately granosely striated, posterior small retuse, 
lateral areas anteriorly decussately granosely striated, 
grains obtuse throughout; ash-green, sparingly 
stained with yellow towards the middle; ligament 
horny, beset with a few bristles.

Hab. New Zealand ; Earl. 
This shell approaches so nearly to the C. Hindsi, that 
it might almost be regarded as a variety ; upon comparing 
it, however, with the young of that species it will be found 
that the grains of the central areas are arranged with 
more longitudinal precision, whilst the posterior terminal 
area is more retuse.

CHITON LONGICYMBA. 
For this species see Plate XXV. Being an extremely 
variable one, I have thought it necessary to give repre. 
sentations of further varieties.
