JO 
MU REX frondosm 
TAB. CCCCXV1 .—Jig. 3. 
Spec. Char. Ovate oblong ; sutures in 8 or 9 
rows, subspinose deeply plaited;] trans- 
verse ridges numerous, rough ; aperture 
obovate; canal straight. 
Syn. Murex frondosus, Lamarck env. de Paris , 
51. Hist . Nat . VII. 573. 
T?his is probably Lamarck’s var. p as the spaces be- 
tween the sutures are simply rough, not scaly ; the 
sutures are so deeply plaited, that their edges are formed 
into a series of almost tubular spines, this being repeat- 
ed upon the several laminae of which the sutures are 
composed, as in most part of the Murices, gives them a 
peculiarly crisp aspect ; the canal is rather broad, and 
half covered. 
The Barton specimens of this beautiful Murex, are 
large and well preserved, but scarce. Miss Beminster 
has supplied me with two or three ; it has also been 
found at Highgate.
