Dr. Waacen™* has figured and described Lytoceras rea., WAaG., 
from the Middle Oolite of Kutch, Western India, which is 
nearly allied to Lytoceras Eudesianum, D’Ors.; it is a magnificent 
specimen, 11} inches in diameter, with thirty fimbrie on its last 
whorl. 
Genus Hamires, Parkinson.—With reference to the Cretaceous 
forms having a conical shell bent in one plane or more without 
the bends being in contact, Professor Nrumayr remarks that a 
spiral curve of a particular curvature does not give sufficient 
data for the establishment of a distinct genus. With this 
view the recognised genera Amnisoceras, Ancyloceras, Baculina, 
Hamulina, Helicoceras, Ptychoceras, and Toxoceras, where the 
curvature receives many modifications, and exists in some of 
the examples in more than one plane, are all suppressed, and 
the whole series reduced to the single genus Hamites, which, in 
the primary significance of the word, implied a conical straight 
shell, as Hamutes elegans, p’Ors. (fig. 44), bent in one plane,

without the bends being in contact. The suture-line is divided 
into six lobes, the principal lobe always the under lateral 
mostly, divided into pairs of branches.
