“Length about 67 mm, rather narrow, mantle less ample than 
in C: mefarlandi, not expanded at the sides; rhinophores and 
branchie wholly retractile; rhinophores stout, with numerous 
transverse lamellz#; branchiz of about 12 large simply pinnate 
plumes, several more or less branched, and so bipinnate at the 
ends; oral tentacles just concealed by mantle; hind end of mantle 
gibbous; foot projecting 20 mm behind end of mantle; breadth 
of sole when crawling 8.5 mm. Color rich dark ultramarine blue, 
edge of mantle and edge of foot bright cobalt blue; rhinophores 
very dark blue; mantle with 2 longitudinal series of oblong very 
bright orange spots, about 7 in a series; 5 round orange spots on 
the anterior part of mantle, in front of rhinophores; under sur- 
face of posterior lobe of mantle with a series of 8 round white 
spots, the hindmost 4 large, the others smaller and rather faint; 
sides of foot with a series of over 10 round or oval orange spots; 
branchize very dark blue, speckled with orange within; sole deep 
blue.’’—Cockerell, Nautilus 16:19.

2039 Chromodoris Porterz 
“Length about 11 mm, form of C: universitatis, but uniformly 
much smaller, and quite different in markings. Deep ultramarine 
blue, including the whole of the foot; mantle with 2 rather 
broad longitudinal stripes of bright orange, not united posteriorly, 
and ending anteriorly at the rhinophores, but anterior to the rhin- 
ophores is a transverse orange stripe; median stripe of C: mefar- 
landi represented by an inconspicuous lighter blue line; margins 
of mantle very narrowly pure white; foot wholly without marks, 
except that the hind end has a suffused whitish stripe. Rhino- 
phores and branchie entirely retractile. Branchial plumes 11, 
in a circle, simply pinnate, entirely of the blue color of the mantle. 
After death, a number of conical white papille (about 9 on each 
side) appear beneath the hind part of the mantle. After deatn 
the blue dissolves out, and the body becomes a sort of pale green- 
ish-blue, with the dorsal stripe very white; and the orange bands 
as in life.’”,—Cockerell, Nautilus 16:20.
