Original illustration of Doris propinquata Pease 1860

Here is another message concerning the white and purple-spotted chromodorids described from Hawaii by Pease and Garrett. In this one I post the original illustration of Doris propinquata, Pease, 1860 

Doris propinquata was originally described (Pease, 1860) without an illustration. Bergh (1881: Pl. G, fig  1-2) subsequently published a painting by Andrew Garrett, which we assume was available to Pease. He called it Chromodoris propinquata.

Here is Pease's description of the external colour:
Colour above bright yellow, becoming white at the margins, which are bordered irregularly with purple; four oblong dots of the same colour in front of the dorsal tentacles. Dorsal tenatcles purple on the outer portion. Branchial plumes edged with the same colour. Length 1 inch 3 lines. This Doris possesses the same habit of vibrating its branchial plumes as Doris vibrata.

Kay & Young (1969) suggest this is probably C. vibrata, because they both vibrate their gills, but it could also be Risbecia imperialis which does the same. The large posterior foot is much more like a species of Risbecia than a Chromodoris.
