2. An Arrangement of Stomatellid^e, including the cha¬ 
racters OF A NEW GENUS, AND OF SEVERAL NEW SPECIES. 
By Arthur Adams, R.N., F.L.S. etc. 
Stomatellid^e. 
Head broad, proboscidiform ; tentacles subulate, with a fimbriated 
lobe at their inner bases; eyes on peduncles at their outer bases ; 
mantle with the front edge entire ; muscle of attachment crescentic, 
open in front; foot with a lateral membrane. Operculum rudimen¬ 
tary or none. Shell imperforate, with a crescentic muscular impres¬ 
sion, open in front. 
The family Stomatellidce differs from that of Haliotidce in the 
mantle not being fissured anteriorly, in the muscle of attachment 
being in the form of a horseshoe round the sides and posterior part of 
the mantle, instead of being oval and central, and in the shell not 
being perforated. In their habits they are littoral, living on coral 
reefs and attached to stones near the shore. Some of the genera, as 
Gena , Stomatella and Stomatia, have considerable locomotive powers, 
and glide, especially Gena, with some degree of celerity. The latter 
genus and Stomatia possess the faculty, common to some other kinds 
of mollusca, of spontaneously detaching a considerable portion of the 
hind part of the foot when disturbed or irritated. 
Stomatella, Lamarck. 
Animal spiral, retractile within the shell; tentacular lobes trian¬ 
gular, with the front edge fringed ; foot small, not tubercular, not
