Genus Hoploscaphites, Nowak. 
At least four species of this genus have been described, but the examples 
are mostly too fragmentary or too immature to allow of definite specific 
identifications.

Of the twelve specimens referable to the group of M. soutoni, five are 
too fragmentary to be definitely identified with any of the types mentioned 
below, but the remaining examples show great variability, as do the specimens 
described by Dr. van Hoepen. The specimen (No. C 19441) referred to as 
close to Baily's type, the suture-line of which was figured by the writer,* 
seems to be the most typical, though it has a considerable number of bifurcat- 
ing ribs. A fragment (C 19469) is probably also close to the type, whereas
