Pareuthria janseni (Strebel, 1905) Fig. 6D

Material examined.

1 spm (10 × 14 mm).

Synonymy.

Euthria janseni Strebel 1905b: 622, pl. 21, fig. 7-7a; Strebel 1908: 28.

Pareuthria janseni , Forcelli 2000: 96, fig. 265.

Remarks.

The specimen analyzed in this study had light spiral stripes on the whole surface of the shell, which is characteristic of this species. Similarly, Strebel (1905b) commented that the last whorl presented 30 spiral stripes. This species is very similar to the species Pareuthria michaelseni , but it can be distinguished by a more globular last whorl, occupying ¾ of the total shell length ( Forcelli 2000).

Distribution.

Magellanic: eastern micro-basin of the Strait of Magellan ( Ríos et al. 2003), Punta Santa Ana (this record), Ushuaia ( Strebel 1905b), Beagle Channel ( Osorio 1999), Picton Island ( Strebel 1905b), and Cape Horn ( Osorio 1999); Puerto Deseado ( Forcelli 2000) and Malvinas/Falkland Islands ( Strebel 1908).
