Neopilina galatheae Lemche, 1957

( Fig. 1 A)

Neopilina galatheae Lemche 1957: 414 , figs 1–4.

Due to the presence of 10 specimens from the type locality: East Pacific, off Costa Rica (09°23'N, 89°32'W),

3590 m, the first record of a living representative of the monoplacophora was not only a sensation but also led

to numerous detailed studies of the morphology and anatomy of this representative of an ancient lineage. Later the species was recollected in abyssal depths from the following localities:

­ specimen number unknown; 3000 km further north of the tip of the southern end of Baja California, 2780–2810 m [it remains unclear whether the author refers to N. galatheae or only to Neopilina sp.] ( Wolff 1961)

­ 3 specimens from Mexico, Baja California, off Cape San Lucas (22°32.5'N, 109°40.8'W), 2781–2809 m ( Parker 1961)

­ 1 specimen from the East Pacific, off Costa Rica (10°07'N, 89°50'W), 3718 m ( Menzies & Layton 1962)

­ 1 specimen (mentioned as “ Neopilina aff. Galatheae ”) from the southeastern Pacific, off Chile (05°51.7'S, 81°48.8'W), 5300–5320 m ( Moskalev 1977).
