CHITON.—Ptate XV. 
sprinkled with sharp solitary granules, posterior edge 
of the lateral areas denticulated, central areas very 
finely granosely striated; dull reddish-brown, den- 
ticles white, ligament horny, transparent. 
Sowersy, Pro. Zool. Soc. 1832, p. 58. 
Hab. Bay of Panama. 
The sculpture of this species is very similar to that of 
C. luridus; it may, however, be readily distinguished by 
the denticulated posterior edge of the lateral areas. 
Species 83. (Mus. Cuming.) 
Curron RETICULATUS Chit. testd oblongo-ovatd, valvis 
terminalibus ceterarum areisque lateralibus radiatim 
liratis, centralibus rudé et creberrime reticulatis ; sor- 
didé fuscé ; ligamento corneo, rugoso. 
THE RETICULATED Curron. Shell oblong-ovate, terminal 
valves and lateral areas of the rest radiately ridged, 
central areas rudely and closely reticulated ; dull 
brown; ligament horny, rough. 
Chiton textilis, var. Sowerby, Conch. Illus. f. 61. 
Hab. West Indies. 
The lateral areas are rather more than usually elevated 
in this species, whilst the central areas are peculiarly reti- 
culated; it has no affinity whatever with C. teatilis. 
Species 84. (Mus. Cuming.) 
CHITON PELLIS-SERPENTIS. Chit. testd ovatd, valdé con- 
ved, valvis subrotundatis, terminalibus, posticd umbo- 
natd, radiatim granatis, ceterarum areis lateralibus 
triradiatim granatis, granis grandibus, solitariis, arets 
centralibus tenuissimé sulcatis ; albidd, caruleo-viridi 
variegatd, maculd trigond nigricante per summitatem 
umbonalem utriusque valve ; ligamento squamato-co- 
riaceo, squamis grandibus, albicante ceruleo-viridique 
tessellato. 
THE SNAKE'S SKIN CHITON. Shell ovate, very convex, 
valves somewhat rounded, the terminal, posterior 
umbonated, radiately grained, lateral areas of the rest 
with three rays of grains, the grains large and solitary, 
central areas very finely grooved ; whitish, variegated 
with dark blueish green or verdigris colour, with a 
triangular blackish spot on the umbonal eminence 
of each valve; ligament squamately coriaceous, scales 
large, whitish, tessellated with blueish-green.

381. pl. 74. £17 to 22. 
Hab. New Zealand. 
Distinguished in all respects from any other species but 
especially by the bold solitary character of the grains. 
Species 85. (Mus. Cuming.) 
Curron Luripus. Chit. testéd ovata, depressiusculd, valvis 
terminalibus ceterarum areisque lateralibus granulatis, 
granulis irregularibus stipatis, ares centralibus subtili- 
ter granoso-striatis ; sordidé fusca aut rubente ; liga- 
mento corneo, rUugoso. 
THE LURID CuHrITon. Shell ovate, rather depressed, ter- 
minal valves and lateral areas of the rest granulated, 
granules irregular, crowded, central areas finely gra- 
nosely striated; dull brown or reddish; lhgament 
horny, rough. 
SowErsBy, Pro. Zool. Soc. 1832. 
Hab. Santa Elena, West Columbia (found attached to 
stones at a depth of five fathoms) ; Cuming. 
Mostly delicately granulated throughout, the granules 
on the terminal and lateral areas beng crowded miscella- 
neously, whilst those on the central areas are arranged in 
longitudinal lines. 
Species 86. (Mus. Cuming.) 
CHITON GRANIFERUS. Chit. testa ovatd, convexiusculd,valvis 
terminalibus ceterarum lateribus granatis, umbonibus 
subrostratis, levibus, antice utringue subtiliter sulcatis ; 
rubente, nigro maculata ; ligamento corneo, translucido. 
THE GRAINED CuITON. Shell ovate, rather convex, terminal 
valves and sides of the rest grained, umbones some- 
what beaked, smooth, anteriorly finely grooved on 
each side; reddish, spotted with black; ligament 
horny, transparent. 
Sowrrsy, Pro, Zool. Soc. 1832. p. 104. 
Hab. Conception, Chili (a single specimen found attached 
to a Mytilus at the depth of nine fathoms), Cuming. 
This species correctly described in the Proceedings of 
the Zool. Soc. appears to have been confounded in Mr. 
Sowerby’s ‘ Conchological Illustrations’ with the C. Gray?.
