Type locality. Sandwich Islands [Hawaii, USA]. Type material. Potential syntypes: ANSP 20686, 1 shell + 2 fragments (11.3 mm long, "ex auct"), ANSP 20687, 3 shells (7.1, 7.2 and 7.5 mm long, "ex auct"), MCZ 31442 and 298486 ( Johnson 1994 ). Remarks. It is not known whether Pease collected the specimens deposited at ANSP and MCZ before or after the species description was published. Therefore, we consider them potential syntypes. Current systematic position. Aplysia parvula Moerch , 1863 (fide Eales 1960 ). Figure 2. Aplysiida types. A-B . Syntype of Syphonota elongata (= Aplysia parvula ), A.
