"cf." is an abbreviation from a Latin word (confer) and means 'refer to' or 'compare with', here it means it could possibly be Samla bicolor or perhaps something closely related, or at least similar in appearance.
Samla cf. bicolor is characterized by its translucent body with a white dorsal region. The cerata are relatively long, basally translucent orange, followed by a broad whitish region, then a broad medial translucent orange region, then whitish again, with a distinctive orange ring at the apices. The rhinophores are whitish orange, basally translucent orange, with an orange tip an an medial translucent orange band. The white oral tentacles are long and smooth.
Samla cf. bicolor differs from Samla bicolor by its long cerata, and by the lack of the flattened tips of the oral tentacles.
It also fits the description and the picture of Catriona sp. in IPN page 371 pretty well, but the rhinophores are not thin and smooth like in most species of the family Trinchesiidae  F. Nordsieck, 1972 .
This species was posted on 24 July 2011 at these websites as Flabellina cf. bicolor (Kelaart, 1858) [Eolis],
Korshunova et al. (2017) reinstated the genus Samla  Bergh, 1900 within the new family
Samlidae  Korshunova, Martynov, Bakken, Evertsen, Fletcher, Mudianta, Saito, Lundin, Schrödl & Picton, 2017,
and moved Flabellina bicolor (Kelaart, 1858) into the genus Samla  Bergh, 1900.
I changed it on 8 December 2017 into Samla cf. bicolor (Kelaart, 1858) [Eolis].
