 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 



subtranslucent, smooth, of a uniform pale lemon-yellow color, 

 very much flattened, resembling some of the Planarian worms. 

 The specimens sent by Or. Taylor are presumably somewhat con- 

 tracted by alcohol, which may account for the form of the rhino - 

 phores and tentacles, which are short, conical, and strongly trans- 

 versely wrinkled, but without tuborculation or color pattern, being 

 of the same pale yellow as the rest of the body. The 'rain ore' 



extending from the right tentacle to the branchial opening is a 



plain line barely perceptible; the brmchial pit with 2 minute lobes

 id even, 

 of the 

 b ises of the posterior tentacles. The general form is elongate 



oval, the ends of the rhinophores, unlike the tentacles, are blunt, 

 and these organs are silicate inferiority as usual. The length of 



the largest specimen, as contracted in alcohol, is about 20 mm., 

 and the breadth about 9 nun. I propose for it the name of P. 



taylori in honor of its discoverer. Of the b other species known, 

 P. hifonti is pale gr-e.m, with darker bands and numerous violet 

 spots; P. depressa is green -buff, variegated with black; and P. lim- 

 acina is of a dusky green. All of these are from western and 



southern Europe/'— Dall Nautilus 14:91-92 (D 1900).
