8. Montiea Puinipri, A. Adams. WM. testa orbiculato-conoi-

convexiusculis, cingulis transversis, equalibus, crenulatis, inter- 
stitiis longitudinaliter striatis ornatis ; margine umbilici callo 
spirali, fusco, radiatim striato cincto; columella in medio 
sinuata, ecallosa, antice obsolete bituberculata. 
Hab. China Seas. Mus. Cuming. 
The species most nearly resembling this is the Trochus Belcheri of 
Philippi, which I imagine is the Trochus calyculus of Wood. 
9. CLancuLus NopuLosus, A. Adams. (Pl. XXVII. fig. 2.) 
C. testa turbinato-conoidea, imperforata, albida, rubro varie- 
gata; anfractibus transversim sulcatis, et cingulis granosis 
ornatis, superne serie tuberculorum coronatis ; sutura canali- 
culata ; anfractu ultimo ambitu sulcato, ad peripheriam tuber- 
culato, basi planiusculo, cingulis granosis ornato; columella

lirato. 
Hab. Van Diemen’s Land. Mus. Cuming. 
This species has most of the characters of a Clanculus, but the 
whorls are nodulous and not granular. 
10. OmpHatiusca.atus, A. Adams. 0. testa orbiculato-conoi- 
dea, apice obtusa, umbilicata, livido-carnea; anfractibus planius- 
culis, cingulis granorum confertis, equalibus insculptis, inter- 
stitiis striatis, ultimo ad peripheriam subangulato ; umbilico 
aperto, intus callo spirali instructo, callo antice dilatato et 
tuberculato ; apertura orbiculari ; columella arcuata, simplice ; 
labro intus levi. 
Hab. Mogador. Mus. Cuming. 
The character of this shell is so peculiar, on account of the inter- 
nal spiral callus of the umbilicus, and the absence of characters which 
constitute allied forms, that I propose to consider it a subgenus of 
Omphalius, under the name of Anadema. 
11. Ompuativs sticricus, A. Adams. O, testa depresso-conica, 
late et profunde umbilicata, rufescente, fusco maculata ; anfrac- 
tibus planis, cingulis nigro alboque articulatis, anfractu ultimo 
ad peripheriam angulato, basi convexa, concentrice sulcata ; 
apertura orbiculari ; umbilico aperto, perspectivo. 
Hab. New Caledonia. Mus. Cuming. 
This is a very pretty little species, of a trochoid form, but some- 
what difficult to refer to any known group; the form is like Chloro- 
stoma, the markings like those of Gibéula, and the umbilicus as in 
Omphalius. 
12. GipBuLA PULCHERRIMA, A. Adams. G. testa umbilicata, 
turbinato-conoidea, alba, flammis coccineis radiatim picta ; an- 
JSractibus convexis, cingulis granulosis, transversis ornatis, ad 
suturas plicato-nodosis, sutura canaliculata; anfractu ultimo 
rotundato, ad peripheriam canaliculato, basi convexa, maculis
