"Length about 67 mm, rather narrow, mantle less ample than 

 in C: mcfarlandi, not expanded at the sides; rhinophores and 

 branchiae wholly retractile; rhinophores stout, with numerous 

 transverse lamellae; branchiae 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; 

 branchiae very dark blue, speckled with orange within; sole deep 

 blue." — Cockerell, Nautilus 16:19.

2039 Chromodoris Porterae 



"Length about 11 mm, form of C: universitatis, but uniformly 

 much smaller, and quite different in markings. Deep ultramarine 

 blue, including tne 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: mcfar- 

 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 branchiae 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 papillae (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.
