When Pease established this group, his intention appears to have 
been that it should include all the minute, ribbed Columbellide 
occurring in the Indo-Pacific region. ‘The only species mentioned 
. by name in the original account of Seminella are Cithara ornata, 
Pse., and C. varia, Pse.; the former name appears to be a manu- 
script one, and it may or may not be the form subsequently 
described as C’tharopsis ornata. Fischer has apparently assumed that 
it is, for he gives the latter asthe example of the group; and if the 
name Seminella is considered worthy of retention, Fischer’s use of 
it for the well-marked group of C. troglodytes is, in my opinion, 
the most appropriate. As has been already mentioned, Pease, soon 
after founding this section, described the genus Citharopsis, in 
which apparently he also included all the small, costate Polynesian 
Columbellide.
