NAUTILUS. 159 
Pautlus raphawtstrunr. 
I do not find any additional information respecting the spe- 
cies either in the writers of the Linnean or of the Lamarckian 
school of conchology. Lamarck has contented himself with 
transcribing the Linnean description for his Orthocera rapha- 
nistrum. 
The only example in the Linnean cabinet that answers ade- 
quately to the definition, and our author, in the tenth edition, 
has indicated his possession of the species, is a large Orthocera 
(pl. 5, f. 4), which looks like that delineated by Soldani in plate 
37, figure M. It may, perchance, be identical with the Nodosaria 
equalis, as delineated in Sowerby’s ‘Genera of Recent and 
Fossil Shells,’ but no description accompanies that engraving. 
The cited figure of Ledermuller exhibits the general aspect of 
the example in the collection, but is so rude as to be irre- 
cognisable. 
Pautilus raphawus. 
Martini’s copies (Conch. Cab. vol. i. vignette 1, fig. A, B, C) 
of the cited engravings of Gualtier are referred to in the re- 
vised ‘ Systema.’ Both are quoted by Lamarck in his syno- 
nymy of Orthocera raphanus. Our author has indicated his 
possession of the species in his copy of the tenth edition of the 
‘ Systema,’ and a specimen which alone answers to the descrip- 
tion is still to be found in his cabinet. It is not unlike the 
figures in Gualtier and Martini, but is less pointed, and, in ac- 
cordance with the description, has the siphon less central than 
depicted in those engravings. 
Pautilus gvanunr 
Although described at some length, it does not seem that this 
species, which, from its declared resemblance to raphanus,
