In the size of the radula and the shape of the teeth the present 
specimens (text figs. 10—12) seem to differ from the type described 
by Eliot (1907, p. 333). In two specimens 
examined the radula had 18 (-|- 2 incomplete) 
rows, the largest with about 40 hamate teeth 
on each side of the bare rhachis; each tooth 
with a bifid or trifid denticle at the outer side 
of the cusp (text-fig. 11). Penis (text-fig. 13) 
and vas deferens were armed with series of 
small hooks in two specimens, but in one (from 
Campbell Island) the hooks were replaced by 
sac shaped projections with inflated ends. In the characters of the 
labial disc, where the elements were indistinct, and of the separate 
hermaphrodite giand the specimens exhibited the typical features.

Chromodoris amoena Cheeseman. 
North Island: 5, 1 sp., much contracted, 1. 24 mm. Though the 
specimen is decolorated, the mantie margin as well as the back of 
the foot still show a deeper yellowish tint than the body in ge¬ 
neral. The radula is large with about 100 rows, the largest con- 
taining about 100 teeth, and these agree, as do the radula and 
the armature of the labial disc, in all the characters described by 
Eliot (1907, p. 345). 
Aphelodoris luctuosa (Cheeseman). 
{A. cheesemani Eliot). 
South Island: 29, 1 sp., 1. about 30, of an ivory-white colour; 
the radula contained only 21 rows of teeth which are in complete 
accordance with the description by Eliot (1907). 
As to the name of the present species, Eliot (1907, p. 343) 
States its identity with Doris luctuosa Cheeseman, but maintains 
that this specific name is to be rejected, because at the time when 
the species was referred to Aphelodoris, viz. 1907, there was already 
an Aphelodoris luctuosa described by Bergh in 1905. As, however, 
Cheeseman’s name dates from 1882, it has priority and must 
be considered valid, and, for the same reason, the later described 
species (from Tasmania), which can, according to Eliot, hardly
