Type locality. “Damotha, prope Moulmein; provincia Tenasserim”.

Material examined. Lectotype (hereby designated: 1 shell marked as “type”, Fig. 5A–K ) ( NZSI M.16941/2), Damotha, Moulmain, coll. F. Stoliczka; 4 paralectotypes (3 adult + 1 juvenile shells [ Fig. 5L–O ]) ( NZSI M.33966/9); 1 shell ( NHMUK 1903.7.1.2856), Tenasserim, Moulmein, coll. Godwin-Austen ( Fig. 6 ).

Remarks. Stoliczka (1871) stated in the original description that very few shells were found. Thus, although one shell in the ZSI was marked as type, it is not a holotype, but a syntype, as the other four shells deposited in the ZSI. The specimen we examined in the NHM may not be a type specimen, because the collector (Stoliczka) is not indicated, but it agrees with the syntypes D. cylindrelloidea , and it was collected at the type locality.

Nevill (1878) mentioned that the “type” of E. cylindrelloidea is deposited in the ZSI. However, this is not considered a valid lectotype designation.
