3. Murex (Preronotvs) specrosus, A. Adams. 
M. testa ovato-fusiformi albida pallide rufo tincta; spira acuta, 
anfractibus septem, porcis transversis distantibus instructis, vari- 
cibus tribus foliatis, plicatis sublaciniatis postice in spina dilatata 
productis ; interstitiis postice nodatis; apertura ovali integra ; 
canali recto, clauso.

This is a very elegant species of Murex, which seems to be some- 
what allied to the M. alabaster of Reeve, and is one of that section 
of the genus with foliated winged varices and a closed canal. 
4. Breua arctica, A. Adams. 
B. testa ovato-fusiformi sordide alba epidermide fusco tenui induta, 
spira aperturam equante, anfractibus 5, erosis longitudinaliter 
plicatis postice noduloso-angulatis, transversim obscure sulcatis, 
anfractu ullimo ventricoso postice carina crenata ornato ; aper- 
tura ovali, labio expanso canali brevi lato aperto; labro tenut, 
postice sinu obsoleto instructo.

This is an example of Bela of rather larger form than most of the 
other species. The genus appears to consist of small Muriciform 
shells, concentrated chiefly in northern regions. 
5. Conus TrariLuim, A. Adams. 
C. testa parva turbinato-conica, spira elata, apice obtuso, anfracti- 
bus convezis, ultimo transversim sulcato, albida fasciis duabus latis 
cinereo tessellatis et puactis cinerascentibus ornata; anfractu ul- 
timo postice rotundato; apertura angusta, lineari, labro simplice 
acuto. 
Hab. Malacca. (Dr. Traill.) 
This is a small and very peculiar species of Conus, unlike in ap- 
pearance to any other example of the genus. The spire is elevated 
and obtuse, and the whorls are convex ; the last whorl is rounded at 
the shoulder and is transversely grooved throughout, and the shell is 
ornamented with two broad bands tessellated with ashy. 
6. Conus sevectus, A. Adams. 
C. testa turbinato-pyriformi, spira elata acuminata, anfractibus 
acute angulatis et fasciis rufis ornatis, anfractu ultimo acutim an- 
gulato ad peripheriam, antice transversim sulcato et angustato ; 
luteola maculis rufo-fuscis, in lineis transversis dispositis, et fascia 
albida antica, ornata ; apertura angusta antice effusa, labro valde 
postice inciso.

7. Rurzocuiius (CoRALLIOPHILA) CALIFORNICA, A. Adams. 
R. testa ovata, alba, rimata spira acuminata, anfractibus convevis, 
longitudinaliter nodoso-plicatis, transversim liratis, liris irregu-
