SIR C. ELIOT: ON DORIDIID®. 333 
‘green, bipinnate, free for nearly all its length, and bearing about 
fourteen primary pinne. At its anterior end is the large prominent 
bifid genital papilla. The verge is conical and grooved; the prostate 
is granulose and T-shaped. The pharynx is a long and narrow tube 
(31 by 3mm.), and though thicker than the rest of the digestive 
tract is not conspicuously muscular as in many other species. It is 
succeeded by a membranous tube which passes straight into the 
hepatic mass without any dilatation which can be called a stomach. 
The greater part of the pharyngeal tube lies under the hepatic mass, 
which is grooved to receive it, and which approaches within 6 mm. 
of the mouth. The free portion of the tube, however, contained 
within this space is bent, and measures 12mm. [I could find no 
salivary glands. The shell is white, and consists of a solute calcified 
whorl much in the shape of a comma. To this is attached a plate, 
the outer part of which is membranous and the inner calcified. 
The important characters of this species appear to be the amplitude 
of the parapodia, shield margins, and posterior processes ; the narrow- 
ness of the pharynx, and the quasi-pinnate rhinophorial organs.

The external characters of this species were described by me from 
a single living specimen captured in Samoa, and deposited without 
being dissected in the Museum of the Academy of Natural Sciences at 
Philadelphia. The animal is of a light tint, varying from pale green 
to fawn colour, with a pattern on the two dorsal shields roughly 
resembling a figure 8. This ight coloration is unusual, if not unique, 
in the genus. 
The specimen now examined was captured by Mr. Stanley Gardiner at 
Rotuma, and is small, 24mm. long and 10mm. broad. The parapodia 
are not at all ample, particularly in front; their greatest width is 
3mm. The head-shield is long and narrow (12 X 5mm.); the edges 
are not very prominent, and the flap behind small. The hinder shield 
is 9 X 7 mm., and bears two short processes about 3mm. long, which 
are quite simple and do not form a disc. The whole body as preserved 
is of a pale indistinct fawn colour. On the head-shield a black bar 
runs down to what may be described as a figure of 8, consisting of 
three, not two, circles placed one above the other. On the hinder 
shield is another figure, which may be described as a figure of 8 with 
the lower circle not closed. A border runs round the parapodia 
about 2mm. from the edge, and at fairly regular intervals sends off 
lines to the edge. On the foot are about ten spots of irregular shape. 
All these markings are very distinct and of an intense black. In the 
living specimen which I saw, the gill was dark green; as preserved it 
is dirty yellow. The digestive tract is much as in the species last 
described. First comes a long, narrow, non-muscular pharyngeal tube 
1 Since writing the above I have read Professor Bergh’s description of the species 
(Semper’s Reisen, tv, ili, 2, pp. 305-6), which in all essential particulars agrees 
with my observations.
