(Figures considerably magnified.) 
Species 185. (Mus. Cuming.) 
Curron corrueatus. Chit. testé ovati, valvis terminali- 
bus radiatim costatis, posticd pared, retusa, areis la- 
teralibus bicostatis, valvis omnibus undique granulato- 
corrugatis; viridi, nigricante maculatd ; ligamento 
arenaceo, tessellato. 
THE WRINKLED CHITON. Shell ovate, terminal valves 
radiately ribbed, posterior small, retuse, lateral areas 
two-ribbed, all the valves granulosely wrinkled 
throughout; green, blotched with black; ligament 
arenaceous, tessellated. 
Hab. ? 
Distinguished by a beautiful surface of minutely wrinkled 
sculpture, the posterior terminal valve being unusally small 
whilst the anterior is large and broadly radiately ribbed. 
Species 186. (Mus. Cuming.) 
Cuiton Exicuus. Chit. testé oblongo-ovatd, subangusti, 
valvis levibus, sulco utrinque summitatem umbonalem ; 
rufescente, albimaculaté. 
THE MINUTE CurTon. Shell oblong-ovate, rather narrow, 
very minute, valves smooth, with a groove on each 
side the umbonal summit; pale red, mottled with 
white. 
Sowersy, Pro. Zool. Soc. 1832. 
Hab. Lord Hood’s Island. 
An extremely minute species of which the characters 
are only to be detected with the aid of a lens of consi- 
derable power. 
Species 187. (Fig. 187. Mus. Hanley, 
Fig. 190. Mus. Forbes.) 
Cuiton Hanutyi. Chit. testé oblongo-ovatd, medio eleva- 
tiusculd, valvis granulis minutis conspicuis, in seriebus 
longitudinalibus ordinatis, pulcherrimé exculptis, circa 
umbones levibus ; albidé aut nigricante tinctd. 
Hanuey’s Cuiron. Shell oblong-ovate, rather elevated 
in the middle, valves very beautifully sculptured with 
conspicuous minute granules arranged in longitudinal 
rows; whitish or stained with black. 
Bran, Thorpe, Brit. Marine Conch. Supp. p. 263. f. 57. 
Hab. Britain. 
Remarkably distinguished from any of the British Chz- 
tons by its conspicuous longitudinal rows of granules, which 
rather approximate in character to those of some of the 
larger exotic species, C. luridus e.g. 
Species 188. (Mus. Cuming.) 
CHITON COLUBRIFER. Chit. testa oblongo-ovatd, medio 
elevatiusculd, valvis terminalibus ceterarum areisque 
lateralibus peculiariter plano-granulatis, centralibus 
strius circularibus et obliquis subtilissime reticulatis ; 
albidd, nigro maculatd ; Uigamento squamoso. 
THE SNAKE-MARKED Cuiton. Shell oblong-ovate, some- 
what elevated in the middle, terminal valves and 
lateral areas of the rest peculiarly flatly grained, 
central areas very finely reticulated with circular and 
oblique strize; whitish, blotched with black; liga- 
ment scaly. 
Hab. iy 
Approximating somewhat in the style of its sculpture 
to the C. rugulatus. 
Species 189. (Mus. Cuming.) 
CHITON PusILLUs. Chit. testé oblongo-ovatd, subangusté, 
minima, medio elevatiusculd, valvis levibus, areis cen- 
tralibus minutissimée punctulatis, valvd posticd terminali 
conspicue umbonatdé ; albidd, rufescente subindistincté 
tincta. 
THE sMALL Curton. Shell oblong-ovate, rather narrow, 
very small, somewhat elevated in the middle, valves 
smooth, central areas very minutely punctured, pos- 
terior terminal valve conspicuously umbonated ; 
whitish, rather indistinctly tinged with light red. 
Sowerrsy, Pro. Zool. Soc. 1832. 
Hab. Pacasmayo, coast of Peru (found on a coral reef in 
seventeen fathoms water, nine miles from land) ; 
Cuming. 
The umbonated summit of the posterior terminal valve 
is somewhat unusually inclined backwards in this little 
species. 
January, 1848.
