MUREX tuberosus. 
TAB. CCXXlX.—Fig. 1. 
Spec. Char. Ovate, pointed, transversely striated, 
with many blunt, short costae upon each 
whorle ; base convex. 
The number and bluntness of the knobs upon this Mu- 
rex are strongly characteristic ; its surface is rendered 
rough by lines of growth crossing the transverse striae, 
which are rather strong ; from the small portion remain- 
ing upon the specimen it appears that the beak is curved. 
A very imperfect specimen of this has been obtained, 
imbedded in a septarium, from High gate hill ; it is the 
one I possess, and the only one I know ; the probability 
of never obtaining better renders it necessary to figure 
this, as well as several other imperfect remains, since it 
is desirable to complete the list of shells found at High- 
gate, in conformity with the first intention of this work. 
MUREX minax. 
TAB. CCXXlX.—Fig. 2. 
Syn. Murex minax. Br cinder, jig. 62. 
Spec. Char. Short, transversely striated, spire 
tuberculated, acute ; last whorle ventricose, 
with two rows of tubercles ; the upper ones 
spiniform, furrowed ; base sulcated ; beak 
curved. 
This Murex is about half as long again as it is wide ; 
the last turn with the beak occupying the greater portion 
of its length. The plaited remains of lips of various ages 
are few, irregular, and but little prominent. 
A rare species from Highgate : I have the same from 
Grignon ; but 1 do not know that it is described by 
French authors.
