Doris (Staurodoris) pustulata, Abraham. 
see Abraham, Pvoc., Zool. Soc., 1877, p 205: Basedow and 
Hedley; Trans., Roy. Soc., S. Australia, xxix, 1905, p. I5I. 
One specimen from the Andamans. About 60 mm. long and 
23 mm. broad—colour yellowish. The branchie are grey and 
darker than the rest of the body, 
Over the dorsal surface are scattered large flat warts or knobs 
of various sizes, and the rims of the branchial and rhinophorial 
pockets are protected by special tubercles. The foot is grooved: 
the tentacles appear to be represented by a lump on either side of 
the head. 
There is no regular labial armature, but the labial cuticle bears 
a granulate stripe, which, if a little more developed, would be 
called a ring of short rods. The formula of the radula is about 
40 X%55.0.55, but many of the rows are incomplete. The teeth 
are simply hamate and erect. The innermost and outermost are 
smaller, but not denticulate or degraded. 
No armature was found in the genitalia. 
This specimen appears to be the D. pustulosa of Abraham, 
of which Basedow and Hedley have given a coloured figure. It 
seems referable to Bergh’s genus Staurodoris, but, as I have pointed 
out elsewhere, if the type of that genus is the D. verrucosa of 
Linneeus, then the genus ought to be called Doris, and Staurodoris 
can be retained as at most a subgeneric designation. 
Chromodoris albo-pustulosa (?), Pease. 
See Pease, Proc. Zool. Soc., 1860, p. 30. 
One specimen from the Andaman Islands, 15 mm. long and 
5 mm. broad. It is white with traces of a darker border. The 
tubercles are yellowish. They are fairly numerous on the dorsal 
surface, especially in the middle, and there are also several in 
front of the rhinophores. They are flattish, about I mm. in 
breadth and ‘5 mm. in height. The rhinophorial and branchial 
pockets are not raised and are not tuberculate. The branchie are 
small and slender, 11 in number, and greyish in colour, with a 
white stripe on the outside of the rhachis. The tentacles are 
inverted. On the underside of the posterior mantle margin are 
eight spherical glands. 
The labial armature is distinct and greyish. It consist of rods 
swollen at the tip and bifid. The formula of the radula is about 
100 X 40.0.40. When looked at as a whole, it gives an impression 
of a great number of long denticles. The teeth are bifid with two 
strong prongs at the tip and 4—6 large, clear-cut denticles below
