983 Phyllaplysia taylori 
“The Rev. Dr. Geo. W. Taylor, of Wellington, British Colum- 
bia, has recently forwarded to me some marine slugs which were 
found on floating sea-grass near Nanaimo, Vancouver Island. An 
examination shows that these animals represent a genus, Phylla- 
plysia, not hitherto known except in Southwestern Europe, and 
an undescribed species. The animal in most respects differs very 
little from P. lafonti Fischer, the type of the genus. It is sub- 
translucent, smooth, of a uniform pale lemon-yellow color, very 
much flattened, resembling some of the Planarian worms. The 
specimens sent by Dr. Taylor are presumably somewhat contracted 
by alcohol, which may account for the form of the rhinophores 
and tentacles, which are short, conical, and strongly transversely 
wrinkled, but without tuberculation or color pattern, being of the 
same pale yellow as the rest of the body. The ‘rainure’ extending 
from the right tentacle to the brachial opening is a plain line 
barely perceptible; the branchial pit with 2 minute lobes is short 
and in about the same relative position as in P. lafonti. The body 
is much depressed and the margins thin, sharp and even. The 
eyes appear as conspicuous small black spots in front of the 
bases of the posterior tentacles. The general form is elongate 
oval, the ends of the rhinophores, unlike the tentacles, are blunt, 
and these organs are sulcate inferiorly as usual. The length of 
the largest specimen, as contracted in alcohol, is about 20 mm., 
and the breadth about 9 mm. I propose for it the name of P. 
taylori in honor of its discoverer. Of the 3 other species known, 
P. lafonti is pale green, with darker bands and numerous violet 
spots; P. depressa is green-buff, variegated with black; and P. 
limacina is of a dusky green. All of these are from western and 
southern Europe.’’—Dall Nautilus 14.91-92 (D 1900).
