CHITON. 
Prate XI. 
Species 58. (Mus. Cuming.) 
Curton ZELANDIcus. Chit. test@ subelongato-ovatd, valvis 
medio levibus, utrinque creberrimé granulatis ; nigri- 
cante-fuscd, lined conspicud luted utrinque summitatem 
umbonalem utriusque value ; ligamento corneo, laté 
expanso, valvarum latera partim obducto, setis perpaucis 
brevibus, spicularum vitrearum cristis densissimis viri- 
dibus munito. 
Tur Znatanp Carron. Shell somewhat elongately ovate, 
valves smooth in the middle, very closely granulated 
on each side; blackish brown, with a conspicuous 
yellow line on either side the umbonal summit of each 
valve; ligament horny, widely expanded, partially 
spread over the sides of the valves, furnished with a 
few short bristles and a row of very dense tufts of 
blueish-green glassy spicule.

Chiton fascicularis, Chemnitz. 
Chitonellus Zelandicus, Gray. 
Acanthochetes Hookeri, Gray. 
Hab. New Zealand. 
This very striking fasciculate species may be regarded as 
the tropical analogue of the C. crinitus of our own shores, 
presenting an almost similar distribution of colour and 
sculpture more highly developed. 
Species 59. (Mus. Cuming.) 
CHITON AMICULATUS. Chit. testd oblongo-ovatd, valvis 
posticd utrinque rotundato-lobatis, medio emarginatis, 
umbonibus subrostratis ; alba; ligamento corneo testam 
tenuiter obducto, undique, nisi ad umbones, brevipiloso, 
setarum cristis parvis perpaucis asperso. 
Tr CLOAK-CLAD Cutron. Shell oblong-ovate, valves 
posteriorly rotundately lobed on each side, emargi- 
nated in the middle, with the umbones slightly 
beaked; white; ligament horny, thinly spread over 
the shell, covered with short hair, except at the um- 
bones, with afew small scattered tufts of bristles.

Chiton vestitus, Sowerby. 
Hab. Arctic Ocean. 
This is without doubt the original species of the amicu- 
late tribe, inhabiting the shores of Northern Europe, de- 
scribed and figured by Pallas in the Transactions of the 
Academy of St. Petersburgh above referred to; the shell 
immediately following, hitherto assigned to this species by 
Mr. Sowerby, is of larger size and entirely enveloped by 
the mantle, of a thick coriaceous cellular structure.

CuITon cuLamys. Chit. testi oblongo-ovaté, valvis levi- 
bus, posticé utringue rotundato-lobatis ; nived ; pallio 
coriaceo, super testam omnino obducto. 
THE cLoak Curton. Shell oblong-ovate, valves smooth, 
rotundately lobed posteriorly on each side; snowy- 
white, mantle coriaceous, spread entirely over the shell. 
Chiton amiculatus, Sowerby (not of Pallas) Tankerville 
Catalogue. 
Hab. ? 
The mantle of this species appears to be of a coarse 
cellular structure, the cells being mostly filled with flat- 
tened warts, as it were, of the same coriaceous substance. 
As shown in treating of the preceding species it is not the 
C. amiculatus of Pallas. 
Species 61. (Mus. Cuming.) 
CuITon TuNIcATUS. Chit. testd oblonyo-ovatd, anticé sub- 
attenuata, valvis medio lird plané latiusculé notatis, 
utringue superficialiter concentricé et radiatim sulcatis, 
et minutissimée punctato-reticulatis ; ligamento corneo, 
late expanso, valvarum latera obducto ; undique nigra. 
THE TUNICATED Cuiton. Shell oblong-ovate, somewhat 
attenuated anteriorly, valves with a rather broad flat- 
tened ridge along the middle, concentrically and ra- 
diately superficially grooved, and very minutely pune- 
tately reticulated on each side; ligament horny, 
widely expanded, spread over the sides of the valves ; 
black throughout.

Hab. Sitka, New Archangel; Sir Edward Belcher. 
Several specimens of this interesting species were taken 
alive by Capt. Sir Edward Belcher at the above-mentioned 
place during the voyage of the Sulphur. 
April, 1847.
