or semilunar, with or without interior teeth on the margin or 
parietal wall ; lip simple or thickened internally or reflected ; 
umbilicus covered to widely open. 
Animal capable of complete retraction within the shell ; the 
jaw finely striate, or ribbed, sulcate, or plicate. 
Itadida : — central teeth tricuspid, laterals bicuspid or tricuspid, 
with an obsolete internal cusp 3 marginals usually wider than 
high, short, with two or three small cusps. 
Distribution : — world-wide 3 about 3,400 species known. 
Pfeiffer, Albers, Beck, Swainson, Ferussac, Tryon, H. and A. 
Adams, and others have proposed a great number of groups 
in which it is generally found that similar ones have a similar 
geographical distribution. Unfortunately there has been a 
lamentable want of consent amongst these and other authors as 
to the grouping, and there is no accepted system which is followed 
V>y the generality of conchologists 3 it would seem in fact as if 
each one had his own. In this list the system of Pfeiffer is 
followed, who makes 86 sections and 67 sub-sections.
