MOLLUSCA 283 
The sculpture of Ka/e//a is finer and transverse to the whorl, so differs still more. 
It therefore may become necessary, if this shell be generally distinct from JZ. ornatella, 
to create a new genus. 
“When we consider the immense area on the Equatorial belt over which Aa/ze//a, 
Sztala, and this allied form are distributed, it appears that they fall naturally into a 
subfamily of their own which may be called the Siratinaz, Godwin-Austen, ome. nov. ; 
one that is sufficiently distinct from the Durgellinae on the one hand, with which they 
are associated over a large portion of their range, and from the Macrochlaminae on the 
other, where the area of association is more restricted and the differences in the animal 
much greater.” (H. H. Godwin-Austen.)
