Berthella sp. from Brazil

February 2, 2006
From: Vinicius Padula

Dear Bill,

I don´t know what species this specimen of Berthella belongs to. Maybe Berthella stellata.

Locality: Rio de Janeiro, Brasil. Atlantic Ocean. Depth: 1 meter. Length: 8 mm. 30 January 2006. Intertidal. Photographer: Vinicius Padula

In the same locality the specimens of Berthella agassizi are pink, with different appearance to this animal (I´m travelling and haven´t photos to send now).

Best wishes,
Vinicius Padula

Dear Padula,
One you stop travelling,  some photos of pink B. agassizi would be very welcome. It's possible these are B. stellata. Marcus (1957) described Berthella tupala from Brazil, which I am pretty sure is now considered a synonym of the widespread B. stellata.
Best wishes,
Bill Rudman
