PHILINE. 3 
synonymy of Philine, but a reference to Adanson’s work shows it 
to be a doubtful synonym and practically useless. 
G. O. Sars has proposed an arrangement of the Scandinavian 
Philines based upon the nature of the gizzard-plates, which may be 
calcified or cartilaginous, and the presence and number of uncini ; 
and his scheme forms an admirable basis for the classification of the 
entire genus. Monterosato proposes several sectional groups based 
on shell contour and sculpture, but as these features change gradu- 
ally as we pass from one species to another, the names he gives are 
hardly worth retaining. If sectional names are required the follow- 
ing scheme may serve until a study of the anatomy of all the species 
still unexamined, gives ground for a natural classification. 
Section PHILINE s. str. 
Shell smooth or with spiral strize or dot-series; type P. aperta. 
Includes Hermania Monts., type P. seabra; Ossiania Monts., type 
P. quadrata Wood; Megistostoma Gabb, type P. striata Gabb not 
Desh.,=P. gabbi Cossm. (Cretaceous). 
Section Laona A. Adams. 
Shell with latticed sculpture. Contains at present two species only : 
P. pruinosa Clark and P. zonata A. Ad. 
Section Jonanta Monts. 
Shell with an external pumice like reticulated layer. Type P. 
vestita Phil. No otherspecies are known to belong to this group.

Subgenus Patiine Ascanius. 
I have above expressed the opinion that the sections Hermania 
and Ossiania are no aid to a right comprehension of the internal 
relationships of this genus. As to Megistostoma, the type specimen 
before me shows no departure of value from typical Philine, except 
that the sculpture is not quite like that of any recent species. ‘The 
evidence of a thick inner lip is most unsatisfactory ; the posterior 
lobe of the lip is more produced than in the average P. aperta, but 
probably not more than extreme forms of that species. It is broken 
off in the type, and so appears more rounded than it really was. 
The following table is slightly modified from Sars. It is much to 
be desired that those species not yet sufficiently known to be inserted 
herein, be examined and their positions indicated.
