160 SPECIES OF THE SYSTEMA. 
apparently belongs to the same genus with it, has ever been re- 
cognised ; at least I do not find any further account of it in any 
of the works I have been enabled to consult: yet, from the 
details mentioned, and the limitation effected by the authenti- 
cated locality, its accurate determination may be reasonably ex- 
pected. Nothing, however, in either the cabinet or the manu- 
scripts of Linnzus dispels the obscurity in which it is at 
present involved. 
Nautilus rvadteula, 
Martini’s copies (Conch. Cab. vol. i. vign. 1, fig. G, G, g.) of 
the illustrative figures in Plancus are added to the synonymy 
in the revised copy of the ‘ Systema ;’ the originals have been 
referred to by Lamarck as illustrative of his Nodosaria ra- 
dicula. 
The figures e and r of Ledermuller are copied from those 
cited in Plancus. 
Pautilus faseta, 
Martini’s copies (Conch. Cab. vol. i. vign. 1, fig. D, d.) of 
Gualtier’s cited engravings are also referred to in the proposed 
new edition of the ‘Systema.’ These figures have been like- 
wise quoted by Lamarck in his synonymy of Orthocera fascia. 
Pautilus sipuncelus, 
Martini’s copies (Conch. Cab. vol. i. vign. 1, figs. F, f.) of 
Gualtier’s referred-to figures are added to the synonymy in the 
revised ‘Systema.’ . These engravings have been quoted by 
Lamarck for his Nodosaria siphunculus.
