1891.| BAKER—ON NEW SPECIES OF MURICID. Let 
but little larger than the first ; the tip of the apex is bent down to one 
side and concealed in the succeeding portion of the whorl; there is no 
carina and the whorls are smooth and glossy in texture, and of a light 
horn color; a view of the lateral outline shows a well rounded profile 
with rather a strong varix at the left side; after passing this varix, 
the whorls are crossed by four spiral lire, which are made nodulus by 
the crowded condition of the varices ; the suture of the embryonic whorl 
is well developed and a trifle impressed. This apex resembles that of 
Murex brevispina, M. nigrospinosus and M. recurvirostris, but is at once 
distinguished by the absence of a carina near the base of the last whorl. 
It more nearly resembles that of AMurex similis, except that the whorls 
are more rounded than those of drandarts. 
This is the only species of the RA‘nocantha group (there are but 
two, the other being cornutus, Z.) that I have been able to study. I 
have before me eight specimens of this species all in perfect condition, 
and the apex shows no variation. © 
Subgenus Chicoreus Monte. 
Murex Rurus, Lam. io

° . . . / 
The embryonic apex of this species consists of* one \ 
broad, flat whorl, which is of a reddish or rosy tinge ; Fic. 2. 
the tip is immersed in the body of the spire, and is considerably bent 
down to one side; there is no carina and the whorl is rough and 
coarse in texture, nearly approaching to granulose ; there is no varix 
at the ending of the embryonic whorl, but the four spiral lire, and 
the longitudinal costz gradually appear and grow stronger as the shell 
increases in size ; the whole apex of the shell for three whorls from the 
top is of a deep rose color. 
Of this species I have seen three examples in perfect condition 
and the characters expressed in the above diagnosis show little or no 
variation. 
Murex Salleanus, A. Ad, may be included here as a synonym. 
I have examined many hundred of this species from Florida, Yucatan, 
and the West India Islands, and do not for a moment hesitate in refer- 
ting this species to rufus. 
Murex PLIcIFERUS, Sowerby. 
The apex of this species consists of two and a half 
rounded, waxy whorls of gradual increase ; the first, or 
tip, is a little oval knob, which is not bent down or 
immersed as in most of the species examined ; a carina Fig. 4.
