CHITON VIRESCENS. Chit. testa ovatd, valvis levibus, mar- 
gine postico crenulatis ; vivide virescente ; ligamento

lated along the posterior edge; bright pale green; 
ligament horny. 
Chiton stramineus, var. Sowerby.

Sufficiently distinguished in form from the C. stramineus. 
Species 127. (Mus. Cuming.) 
Curron coarcratvs. Chit. testd oblongo-ovatd, valvis medio 
levibus, subrostratis, ared reniformi utringue minute 
granuloso-aspera, deinde levigatd, valvd posticé termi-

THE CONTRACTED CuiToNn. Shell oblong-ovate, valves

SowErsy, Pro. Zool. Soc. 1841. 
Hab. Island of Bohol, Philippines; Cuming. 
The sculpture of this shell is very similar to that of the 
fasciculate species of the Mediterranean. 
Fig. 128 and 133. (Mus. Cuming.) 
Notwithstanding the apparent dissimilitude in these 
shells, Iam forced to the conclusion that they are both 
varieties of the C. rugulatus, Sp. 118, 
For Sp. 128 and 133, see Plate XX VI. 
Species 129. (Mus. Cuming.) 
CHITON PUNCTULATISSIMUS. Chit. testd ovatd, levi aut, 
sub lente, minutissime reticulata, et obscure puncturata ; 
luteo-rufescente, concinné lentiginosd, interdum hic illic 
intense rubido-castaned ; ligamento minutissimé squa- 
muato-coriaceo. 
THE FINELY PUNCTURED CurIToNn. Shell ovate, smooth, 
or, under the lens, very minutely reticulated, and 
obscurely punctured ; yellowish-red, prettily speckled, 
sometimes stained in parts with deep reddish chesnut ; 
ligament very minutely squamately coriaceous. 
SoweErsy, Pro. Zool. Soc. 1847. 
Hab. Shores of Peru, (found on dead shells at a depth of 
from six to ten fathoms) ; Cuming. 
Obscurely punctured and neatly freckled in colour 
throughout. 
Species 130. (Mus. Cuming.) 
CHITON CATENULATUS. Chit. testd subelongato-ovatd, 
valvis terminalibus ceterarum areisque lateralibus striis 
concentricé rugulatis, centralibus creberrime minute 
liratis ; virescente-flavd ; ligamento corneo. 
THE CaTENULATE Carton. Shell somewhat elongately 
ovate, terminal valves and lateral areas of the rest 
wrinkled with concentric strie, central areas very 
closely minutely ridged; greenish yellow, ligament 
horny. 
SowErBy, Pro. Zool. Soc. 1832. 
Hab. Inner Lobos Island, coast of Peru (under stones at 
low water) ; Cuming. 
Partaking rather of the character of C. rugulatus. 
Species 131. (Mus. Cuming.) 
Curron PALLIDULUS. Chit. testd elongata, valvis termi~ 
nalibus ceterarum areisque lateralibus concentricé 
undulato-rugatis, centralibus minute asperis ; undique 
albidé ; Uigamento corneo, arenaceo, albido. 
THE PALE Curron. Shell elongated, terminal valves and 
lateral areas of the rest concentrically undulately 
wrinkled, central areas minutely rough; whitish 
throughout ; ligament horny, arenaceous whitish. 
By 
Hab. 
In detail of sculpture, this shell is not much unlike the 
C. rugulatus, from which however it may be distinguished 
by the semilunar form of the valves. 
Species 132. (Mus. Cuming.) 
CHITON PULCHERRIMUS. Chit. testd oblongo-ovatd, medio 
subangulatim elevato, valvis terminalibus conspicué 
tricostatis, costis nodulosis, ceterarum areis lateralibus 
tricostatis, costis quoque nodulosis, areis centralibus
