INDIAN NUDIBRANCHIATE MOLLUSCA. 117 
margin surrounded by thick-set purplish-brown blotches; the extreme edge pale: 
under side yellowish orange, with large dark brown circular spots, intermingled with a 
few smaller and lighter ones; the margin blotched with brown. Dorsal tentacles 
clavate, with brown lamine, and retractile within slight sheaths. Oral tentacles short, 
linear. Branchial plumes six, retractile within a cavity, the margin of which is pro- 
duced into six lobes, as in D. formosa; anal tube long and narrow. Foot orange- 
coloured, narrowish, rounded at both ends, and slightly laminated and notched in front. 
Length from 23 to 3 inches. 
A variety has the cloak of a dark brown above, obscurely blotched and spotted: the 
under side of a deep orange, with very large deep-brown spots. 
Tongue as in D. tuberculata. 
This fine species is common on the Coromandel coast. Two specimens are preserved 
in the collection. 
Doris paRDALIS, n. sp. (Pl. XXVIII. fig. 3.) 
Body oval, slightly elongated. Cloak covered with very small, pointed tubercles ; 
the surface yellowish, pretty regularly covered with rufous spots, inclining to orange, 
largest towards the centre of the back. Under surface pale yellowish white, with faint 
reddish spots. Dorsal tentacles clavate, rather slender, reddish. Oral tentacles small, 
linear. Branchial plumes six, rather large, slender, tripinnate ; anal nipple prominent, 
the margin six-cleft. Foot oblong, rounded at both ends, whitish, without markings, 
excepting a few scattered dark freckles ; the front laminated, but not notched. Length 
about 2 inches. 
Tongue as in the last species, with the addition of a prehensile collar. Doris pardalis 
bears great resemblance to D. concinna (described below), but differs in having the 
tubercles smaller, and the markings of the cloak more regular and of a different colour. 
The branchial aperture, too, is lobed in this species, which is not the case in D. 
concinna. 
Rare. One specimen is preserved in the collection. 
Doris striata, Kelaart. (PI. XXI1X. fig. 4.) 
Body depressed, elliptic-oblong, yellowish brown. Cloak ample, firm, coriaceous, 
minutely granular or tuberculated, of a yellowish or rusty-brown colour, paler or whitish 
towards the margin, a little marbled on the back, and everywhere covered with fine 
waved brown lines for the most part arranged in a radiated manner. Under surface 
white, with waved and branching brown lines near the foot. Dorsal tentacles stout, 
clavate, and pointed, with purplish lamin ; the apex white; margins of the orifices a 
little produced, and whitish with brown streaks. Oral tentacles linear, white, and 
grooved on the upper surface. Branchial plumes six, imperfectly quadripinnate, beau- 
tifully streaked with dark brown, the streaks following the lines of the stem and
