Oral tentacles linear, projecting considerably beyond the 
mantle border when in motion. 
Radula. Lateral spines numerous, about 30 ; hooked, 
the inner edge denticulated ; surmounted on a strong base. 
Dim. — Length 34, breadth 8 mm.

Albania (?) verconis, spec. nov. 
Plate iv., figs. 1-4. 
Body oblong-ovate, rounded in front, moderately .flat- 
tened on top ; sides elevated ; a strongly acute tail with a dis- 
tinct central dorsal ridge, extends beyond the mantle edge 
when in motion ; on death this tail curled up. Colour, exqui- 
sitely tinted dorsally, with faint, semi-transparent, reddish- 
violet near the border, fading imperceptibly to a light brown 
in the central region, which is further traversed by a fine net- 
work of opaque white lines, not discernible nearer the margin ; 
ventrally of a uniform pale violet. Mantle serrated along the 
sides, and in parts upturned, produced frontally. Head, 
large, distinct. Foot acutely pointed, with a border frill. 
Rhinophores small, clavate, laminate, with about twelve 
lamina, non-retractile. Genitalia large, situated about one- 
fifth the whole length from the anterior end. Branchial 
plumes ten, simply pinnate, completely surrounding the vent, 
non-retractile ; colour, opaque white. 
Radula. Colour, brownish-yellow, deepest in shade at 
the dilated end of odontophore. Lateral spines, about 22 on 
either side, stout, hooked, the central four or five trifidated. 
No rachidian. About 42 straightish rows in specimen examin- 
ed. 22-0-22. 
Dim. — Length 27, breadth 11, height 9 mm. 
Hah. — A single individual dredged in 20 fathoms, off 
Antechamber Bay, Kangaroo Island, January, 1903 (Vercj). 
Ohs. — With considerable hesitation we have referred this 
species to Alhania. The general appearance, branchiae, and 
serrate edge of the mantle suggest this genus. Dr. Colling- 
wood describes a frontal veil in the type-species ; this was not 
observed in the living animal. The only specimen that was 
found has so shrunk that we cannot now decide on its ab- 
sence or presence.
