GASTEROPODA. 299 
branchial plumes are gashed very much, like the leaves of the Acan- 
thus, or of parsley.

branchial plume, enlarged ; 393 c, anal tube, enlarged. 
Doris avrita (Gould). 
D. elongata, depressa, anticé truncata, sanguinea, pustulis raris instructa ; 
tentaculis et branchits sulphureis: tentacule cervicales brevi, recurve, 
ad apicem oblique laminate ; stella branchialis magna, foliis octo invo- 
lutis, plumosts, albidis ; tubus analis simplex, curtus ; regio anterior 
Jimbrits lateralibus auribus simulantibus, et area inferiort (an ore?) 
sulphureo marginatis insignis: pes angustus, lateritius ; margine 
flavo. 
Body elongated, rather depressed, somewhat truncate anteriorly. 
Colour bright crimson, with small scattered tubercles, resembling full 
pustules, which with the tentacles, branchi#, and margin of the body, 
are sulphur-yellow ; cervical tentacles short, stout, recurved, obliquely 
lamellate at tip. Branchial star large, nearly as wide as the body, 
with eight large incurved plumes, like ostrich plumes, becoming 
white towards their tips; anal tube very short, simple. Near each 
anterior angle there is a curious lateral, earlike appendage, or crypt, 
tipped yellow, and a similar transverse area beneath, perhaps the 
mouth. Foot pale brick-red, margin yellow. 
Length three and a half inches; breadth an inch and one-fifth. 
Obtained from a reef, Sandalwood Bay, Feejee Islands. 
This animal bears a general resemblance to D. aurea, Quoy, which 
has but five branchial plumes, with lines of small dots along the 
body. The figure seems to have been taken when the animal was in 
a contracted state, and the parts about the head are not well made 
out. Itis quite probable that appendages are protruded from within 
the earlike fringes answering to the labial tentacles.

anterior portion.
