Remarks.— Jorunna funebris is a well known but poorly documented species, only recently coming under review (Camacho-Garcia & Gosliner, 2008). The group found together at RBE station 1 are well preserved. The patches of black vary in size and intensity, as usual for the species. Jorunna funebris is widely distributed in the Indo-West Pacific and Red Sea, and was recorded from Indonesia previously by Bergh (1890) and Tonozuka (2003).
The record from Singapore (Lim & Chou, op. cit.) was omitted from the 2008 review, possibly because Marcus (1976) had assigned it to Discodoris ? maculosa (no authority) based on the description of the jaws. However, not only do Lim & Chou identify their specimens as Discodoris annuligera in the addendum of the same publication, but their description and figures match published records. There are two species of D. maculosa: that of Cuvier, 1804, designated a nomen dubium by Dayrat (2010), and that of Bergh, 1884, synonymised with Tayuva lilacina (Gould, 1852), also by Dayrat (op. cit.). Since the latter is a Mediterranean and European Atlantic species, presumably Marcus was referring to Cuvier’s species, which is deemed unidentifiable. There is a dilemma in that Lim & Chou described pointed jaw rodlets from one of their specimens, which is not a character of Jorunna, and the item which caused Marcus to think it was a species of Discodoris.
