Tethys robertsi Pilsbry, 1895 Figure 5 A–D

Tethys robertsi Pilsbry, 1895: 89; 1896b, pl. 55, figs 5, 6.

Type locality.

West coast of Mexico.

Type material.

Holotype (original designation, "the type"): ANSP A7029, 1 specimen (ca 92 mm long preserved; W.H. Jones, leg.) [shell removed and figured by Pilsbry (1896b: pl. 55, fig. 5) but not found, should be ANSP 66307].

Remarks.

Pilsbry (1895) cited plate 55, figures 4 and 5, but when the plate was published the next year, the captions showed figures 5 and 6, the latter being correct. The specimen has the sole covered by small black dots (Fig. 5D), which is not mentioned in the original description nor by Eales (1960).

Current systematic position.

Aplysia robertsi (Pilsbry, 1895) (fide Eales 1960).
