Discodorididae 
Carminodoris bramale (Fahey and Gosliner, 2003). Playa Pichilingue, La Paz, Baja Califor¬

Eugenia, Baja California Sur (Bertsch et al. 2000). 
Previous northe rnm ost locality: Paradise Cove, Malibu, Los Angeles Co., California (Behrens 
and Henderson, 1981). 
Remarks: The specimen from Santa Cruz Island appeared to be dull orange to rust colored, but 
had the distinctive “halos” of lighter pigment around the rhinophores and gill plume described by 
Behrens and Henderson (1981) for this species (Figure ID). 
Few specimens of this Californian species have been found since its original description 
(Behrens 2016), so it is noteworthy that “dozens” have been observed, including some mating and
