Subfam. Tergipedinae.

This group contains forms with a somewhat compressed body, simple rhinophores, and a latero- 



al position of the anal papilla; the dorsal papilla; are short and thick, clubshaped, and, as it were, 



arranged in one or a few longitudinal series; the foot is rounded anteriorly. ■■ The masticatory edge 



of the mandibles bears mostly a single series of denticles; the tongue has most frequently only a 



singli of tooth-plates. The otocyst contains only a single otolith. 



The family comprises the genera: Tergipes (Cuv., Aid. et Hanc) with a single series of papillae 



and unarmed penis; Capcllinia (Trinchese) also with onlj one series of papillae, but with three series 



loth-plates dike the Galvinae) and with armed penis; Embletonia (Aid. et Hanc.) has one or more 



i papillae, a smooth masticatory edge, and unarmed penis; nearl) related with this genus is 



'1.1, which has, however, real tentacles land not head-lobes). Amphortna (Quatrefages) has 



largi Gl. ptyalinae, and armed penis; Galvina (Aid. et Hanc) has three series of 



GL ptyalinae, hut unarmed penis; Myja (Bgh.) resembles somewhat Tcrgipes, but has 



:100th masticatory edge; perhaps also the singular Forestia (Trinchese) in which the radula is 



rmed inti ••.ted hand, must be referred to this family.
