30. Doris PICTA. 
Form, when at rest, oval ; soft, similarly rounded at both extre- 
mities, and convexly rounded above. Mantle not concealing the 
foot, rather widest in the middle, and the margins thin and very 
slightly undulated. Branchiz small, suberect, curving centrally, 
ten in number, decreasing in size posteriorly, encircling the vent, 
and retractile into a common cavity; each branchia is subquadran- 
gular, tapering to a point and ciliated. Dorsal tentacles rather small, 
ovate, with short peduncles, obliquely lamellated and retractile into 
simple cavities. Foot elongate, extending beyond the mantle, ter- 
minating in an acutely rounded point, the margins slightly undu- 
lated. Labial appendages small, cylindrically tapering to a blunt 
point. Colour white, with small irregular white spots. Obsolete 
yellow spots along the margin, which, as well as the foot, is bor- 
dered with orange. The angular edges of the branchiz edged with 
carmine. ‘Tentacles tipped with orange. 
Length 1 inch 6 lines. 
31. Doris NUCLEOLA. 
Form oval, rigid, rounded at both extremities and convexly 
rounded above. Mantle covers the foot, margins thin, upper sur- 
face rough, with remote papillee and small laciniated processes, which 
are most conspicuous posteriorly. Branchial plumes small, erect, 
five in number, pinnate, surrounding the vent, and retractile into a 
common cavity. Dorsal tentacles ovate, acute, closely and finely 
lamellated obliquely. Foot oval, rounded at both ends. Colour 
orange, dusky along the dorsal region, and shaded with purple on 
each side of the branchiz. 
32. Doris DECORA. 
Oblong, smooth, soft, and convexly rounded above. Mantle 
rounded in front, acutely rounded behind. Margins thin and 
simple, not covering the foot behind. Branchial plumes small, 
nearly erect, seven in number, pinnate, decreasing in height poste- 
riorly, surrounding the vent and retractile into a common simple 
cavity. Dorsal tentacles elongate-ovate, obliquely lamellated, pe- 
duncles as long as the lamellated portion, retractile into simple cavi- 
ties. Labial tentacles small and conical. Foot narrow, rounded in 
front, tapering behind to an acuminately rounded tip, projecting 
far beyond the end of the mantle. Colour: Dorsal region pale 
straw-colour, with a medial whitish longitudinal stripe, which is 
bifurcated posteriorly and dotted with purple. The margin of the 
mantle is bordered with white and dotted with purple; an intramar- 
ginal light red band, contiguous to which is a yellow one, which is 
dotted with purple. Branchie and tentacles pale. Beneath the 
enantle is coloured as above, but much paler. 
Length 1 inch 2 lines. 
This truly magnificent species was obtained on sea-weed. The 
specimens were very active, and when creeping resemble a Goniodoris 
in outline.
