abrasion. Under side of" mantle wiiite, sj^arsely dotted with 
large and small black spots, irregularly spaced. Foot rounded 
in front, sides approximately parallel and slightly frilled, 
ending posteriorly in an obtuse point, much narrower than 
mantle ; colour opaque white, fringed with a deep orange-yel- 
low border. Dorsal tentacles comparatively small, trun- 
cated, retractile within low sheaths, brown at the summit, 
white at the base. Oral tentacles, fairly long, linear, rounded 
in front. Genital aperture inconspicuous, situated about 
one-third the whole length from anterior end. Branchial 
plunles six, small, black, finely laciniated. 
Radula light straw-coloured. Lateral spines numerous, 
about 40 on either side : hooked, smooth, rapidly increasing 
in size outwards, the three most lateral, however, small. 
Average height of spines, "38 mm. No central spine. About 
40 curved rows in specimen examined. Formula, 40'040. 
Dim. — Total length 45, breadth 30, length of foot 42 mm. 
Hah. — Dredged in 20 fathpms, off Antechamber Bay, 
Kangaroo Island, January, 1903 (Verco). Dr. Verco has 
dredged two individuals of this peculiar form on two sepa- 
rate occasions. In the Australian Museum, Sydney, there is a 
single specimen, collected on the beach at Middle Harbour 
after a gale, which is probably identical. 
Oh 8. — Bergh's definition of BnJc/erdd mentions that the 
lateral teeth of the radula are furnished with fine denticules, 
but as Eliot finds (Proc. Zool. Soc, 1903, p. 373) that this is 
not a constant feature, we have not considered the simple 
teeth of our species a bar to its admission in this genus. 
The remarkable and artificial appearance presented by 
the ornamentation of this species resembles the hieroglyphic 
markings of primitive man, and suggests the species-name. 
Hypselodoris epicuria, i<pec. nov. 
Plate vii. figs 1-3. 
Body elliptic, oblong, fairly convex, highest in region 
anterior to branchiae. Mantle spiculose, of a rich red colour

tapering behind ; border waved : colour white, with a single 
row of largish yellow dots along the upper edge, and the
