Gen. AETHEDORIS. 
Alder & Hancock figure in vol. 5 of the Zoological Suciety’s ‘Tran- 
sactions,’ a form belonging to a new genus “‘ apparently related to 
Goniodoris.” As no specimen came into their hands, they could 
give no description. The most striking characteristic, seen in the 
drawing, is the expansion of the bilobed head, each lobe being semi- 
crescentic, with the apex curving backwards and the margin bearing 
12 to 14 conical dentations. 
A. INDICA. 
Figured, Alder & Hane. Trans. Zool. Soc. v. pl. 33. f. 20 (1864). 
Hab. Madras coast. 
Gen. Inari, Leuckart (1828). 
Euplocamus, Philippi (1836, part of). 
Body convex, smooth. Mantle indistinct, the margin bearing fila- 
ments, generally longest in front. The head is produced anteriorly. 
Rhinophores linear, laminated. Branchie simply pinnate, non- 
retractile. Odontophore with 4 spines in each tranvserse row, the 
two middle ones large, no central spines. A spinous buccal collar. 
Messrs. Alder & Hancock have thus divided the species :— 
a. Centre of back with filaments. Inner lingual spines falcate and 
nearly smooth ; external spines short. Spinous collar complete.

1 The figure seems to show that the rhinophores are retractile; if so the animal 
cannot be a Goniodoris; there is no means of judging as to the retractility of 
the branchize, which are ‘‘yoluminous and ramifying” and therefore probably not 
belonging to Chromodoris, The elongated tubercles covering the body and the 
sober coloration are also not characteristics of a Chramodoris.
