MUREX. 299 
Murex Badplontus, 
The Pleurotoma Babylonia of authors (Sowerby, Conch. Man. 
f. 8379) is marked for this species in the Linnean cabinet. In 
the revised copy of the ‘Systema’ 52 (as in the ‘Museum Ul- 
rice’) has been substituted for 51 in the reference to Gualtier : 
the synonymy thus amended becomes correct, although some 
of the cited figures are of rather rude execution. ‘The details of 
the ‘Museum Ulric’ answer to the well-known characteristics 
of this graceful shell. 
Sluvex Favawius. 
The Plewrotoma nodifera (Crouch, Introd. Lam. Conch. pl. 17, 
f. 4) of authors is marked for this species in the Linnean cabinet, 
and correctly agrees with its description. 
i 
Murex cols, 
The Fusus colus of authors (Martini, Conch. Cab. vol. iv. 
pl. 144, f. 1842) is marked for this species in the Linnean 
cabinet. Naturalists have long recognised that shell as the 
more typical form of colus, through the description in the 
‘Museum Ulvice,’ and the careful selection in that work of the 
only three figures (Rumphius, Gualtier and Argenville) that are 
really illustrative of the intended type. Klein’s cited drawing 
is a bad copy of Lister, plate 917, f. 10, which Deshayes 
refers as a variety to Fusus colus. The synonymy in the 
‘Systema’ is very bad, especially in the twelfth edition, where 
F. longissimus was introduced by the reference to Seba (19 was 
a misprint for 79; plate 19 only contains Crustacea), and great 
latitude of variation permitted by the addition of “ Variat 
ventre tereti et angulata.”
