CONUS. 161 
Nautilus legume. 
Ledermuller’s engravings, only referred to in the final edi- 
tion, were taken from the cited ones of Plancus, from which 
the figures HE, e, of the first vignette in Martini’s ‘ Conchylien 
Cabinet’ (vol. i.), which are annexed to the synonymy in the 
revised ‘Systema,’ were likewised copied. These illustrations, 
as well as the cited one of Gualtier, have been quoted by 
Lamarck for his Orthocera legumen. 
Nautilus orthocera, 
The long list of localities, inserted by Linneus in the ‘ Mu- 
seum Tessinianum, is not devoid of utility; since, coupled 
with the circumstance of the indicated ‘“ Alveolus,” it has fur- 
nished us with a clue to the species intended by our author. 
It appears that the only two Orthoceratites provided with an 
alveolus (the siphuncle) to be met with in the enumerated dis- 
tricts are the O. duplex and the O. vaginatus, to the latter 
alone of which (delineated by De Verneuil in Murchison’s work 
on Russian fossils, pl. 24, f. 6) can the “ carinato-striatis” of 
the description beapplied. That fossil may, consequently, be 
regarded as the Nautilus orthocera of Linneus. 
I am indebted to Mr. Salter for the above information.
