SCALARIA PoRRECTA. Scal. testd ovato-elongatd, fused, politd ; an- 
Sractibus octonis, connatis, superne rotundatis; costis acutis, 
superneé aculeatis ; anfractu ultimo septemdecemcostato, pallide 
fasciato ; aperturd ovali, ad basin truncato ; umbilico nullo. Axis 
43 lin. 
Hab. Straits of Malacca; from seventeen fathoms, among mud. 
ScaLarts vutpina. Seal. testd elongatd, fuscd ; anfractibus nonis 
rotundatis, connatis; costis obtusis, rotundatis, lineis elevatis de- 
cussatis ; suturd profundd ; anfractu ultimo novemcostato, ad basin 
obtuse carinato ; aperturd rotundd ; umbilico nullo. Axis 3 lin. 
Hab. Island of Quibo, Veragua, Central America; from thirty 
fathoms, among mud; the temperature below being 58°, and at the 
surface 82°. 
A pretty little shell, which, under first impressions, the propriety 
of placing in Scalaria might be called in question, though it pos- 
sesses the characters assigned to the genus. Still there is a differ- 
ence of character and appearance, which creates a momentary hesi- 
tation. But, together with its deep suture, the basal whorl is pro- 
vided at its inferior surface with a blunt keel, which is also to be 
met with in a few other species of Scalaria, but I am not aware in 
any other genus, and which induces me to place it here without the 
least doubt as to the propriety of its location. 
The following new species of Murex were collected, with three 
exceptions, during the voyage of the Sulphur, under the command 
of Sir Edward Belcher, C.B., and figures of them will shortly be 
published in the ‘ Zoology’ of the Voyage. These descriptions are by 
Mr. Hinds. 
Murex AntILLarum. Mur. testd subfusiformi, pallidd, trivaricosé ; 
anfractibus septenis rotundatis ; varicibus tribus rotundatis, spi- 
niferis, postice fornicatis ; ad angulum anfractuum spind unicd 
elongatd, deinde quinque breviusculis ; interstitiis tri-, vel rariis, 
quadri-fariam noduloso-costatis, lineis transversis fuscis penicil- 
latis ; canali elongato, aperto, prope anfractum basalem subflexo, 
spinis duabus cavis gerente. Axis 18 lin. 
Hab. Tortola, West Indies. Mus. Cuming. 
This shell is another of those typical forms of Murex which have 
recently become somewhat numerous, and which appear to be con- 
fined to the tropical seas. I am strongly disposed to think that it is 
meant to be represented in fig. 69 of the ‘ Conchological Illustrations,’ 
which is mentioned as a variety of M. Motacilla, though there are 
still some little points of difference. A fine specimen often permits 
a conchologist to clear up his doubts as to specific importance, and 
I have had the assistance of such in drawing up the above descrip- 
tion. Indifferent specimens are not uncommon, and Mr. Sowerby, 
jun. had most probably only such, and was compelled to leave it as 
a variety of M. Motacilla. 
Murex centriruca. Mur. testd gracillime fusiformi, pallide cor-
