CHITON.—Ptate II. 
punctured engraving which is not visible to the unassisted 
sight; it is yet more closely allied to the C. levigatus, 
but may be distinguished by its broader growth. 
Species 8. (Mus. Cuming.) 
Cuiton Goopatiit. Chit. testd oblongo-ovatié, subgquad- 
rata, valvis terminalibus ceterarum areisque lateralibus 
punctis elevatis minutissimis subdistantibus aspersis, 
centralibus levibus, concentrice striatis ; olivaceo-nigra; 
ligamento squamato-coriaceo, squamis subumbonatis, 
nigro aut viridi-marmorato. 
Goopat.’s Carron. Shell oblong-ovate, somewhat square, 
terminal valves and lateral areas of the rest sprinkled 
with very minute rather distant raised dots, central 
areas smooth, concentrically striated; olive-black ; 
ligament squamately coriaceous, scales slightly um- 
bonated, black or green-marbled.

Hab. James Island, Gallapagos (in exposed situations, 
also under stones and ledges of rock); Cuming. 
This fine species, named after the late venerable Provost 
of Eton College, was the first newly described shell of Mr. 
Cuming’s collection. From C. magnificus, which it ap- 
proximates in general aspect, it may be at once distin- 
guished by its more oblong-square form, and want of lon- 
gitudinal grooves and divergent ridges ; in some specimens 
there is a series of faint blueish-green dashes on either side 
of the wmbonal eminence. 
Species 9. (Mus. Cuming.) 
Cuiton Bowernt. Chit. testd subelongato-ovatd, medio 
angulato-elevatd, valvis terminalibus ceterarum areis- 
que lateralibus radiatim ewiliter tenuisulcatis, centralibus 
levibus, concentricé striatis ; fusca, valvis spadiceo hic 
illic anticé flammulatis ; ligamento subtiliter granoso- 
coriaceo, nigro. 
Bowen’s Curron. Shell somewhat elongately ovate, an- 
gularly elevated in the middle, terminal valves and 
lateral areas of the rest faintly finely grooved, central 
areas smooth, concentrically striated; brown, valves 
marked here and there on the anterior portion with 
fawn-coloured flames ; ligament finely granosely coria- 
ceous, black.

Hab. Strait of Magalhaens ; King. 
Of a curious elongated form, peculiarly elevated along 
the umbonal eminence. 
Species 10. (Mus. Cuming.) 
CHITON AUSTRALIS. Chit. testé oblongo-ovaté, valvis ter- 
minalibus ceterarum areisque lateralibus radiatim 
liratis, iris subgranosis, rude undulatis, hic illic bifa- 
riam divergentibus, areis centralibus rudé longitudina- 
liter granoso-liratis, umbonibus levibus ; viridi-nigri- 
cante, medio viridiore umbonibus roseis; ligamento 
fortiter granoso-coriaceo, nigricante. 
THE SOUTHERN CurTon. Shell oblong-ovate, terminal 
valves and lateral areas of the rest radiately ridged, 
ridges subgranose, rudely undulated, here and there 
bifariously divergent, central areas rudely longitudi- 
nally granosely ridged, umbones smooth; greenish 
black, greener towards the middle, umbones pink; 
ligament strongly granosely coriaceous, blackish.

An eadem? Chiton evanidus, Sowerby, Conch. Illus. f. 139. 
Hab. Australia. Raines’ Island, Torres Straits; Ince. 
The very dark green body and pink umboes of this 
shell afford a contrast of colour similar to that exhibited 
of lighter hue in the C. Magdalenensis. 
Species 11. (Mus. Cuming.) 
CHITON ALBILINEATUS. Chit. testd subelongato-ovatd, 
valvis terminalibus ceterarum areis lateralibus levibus, 
nigricantibus, lineis subelevatis undulatis, interruptis, 
rugisve subdistantibus, conspicué albis, radiatis, areis 
centralis levibus, aut hic illic nigricantibus aut omnino 
cinereo-albo pulcherrimé et minutissime concentricé un- 
datis, summitate umbonali nigricante, lird lata longi- 
tudinali albidé utringue notatd, ligamento granoso- 
coriaceo, cinereo-albo. 
THE WHITE-LINEATED CuHItTon. Shell somewhat elon- 
gately ovate, terminal valves and lateral areas of the 
rest smooth, blackish, radiated with rather distant con- 
spicuously white, interrupted, waved, slightly raised 
lines or wrinkles, central areas smooth, here and 
there black or altogether very beautifully minutely 
concentrically waved with ash-white, umbonal emi- 
nence black, marked with a broad longitudinal white 
line on each side; ligament granosely oriaceous, pale 
ash. 
Sowsrsy, Zool. Journal, vol. iv. p. 368. 
Hab, Guaymas, Gulf of Califormia. 
The white radiated painting of this species is remark- 
ably characteristic; on a black ground, it exhibits an un- 
usually effective contrast.
