126 LIVERPOOL MARINE BIOLOGY COMMITTEE REPORT. 



with orange tentacles surrounding a dull blue disc, but 

 these were so injured by the attempt to detach them that 

 they died without expanding, and whether these belonged to 

 the variety nohilis, Gosse, first brought under his notice by 

 the Honourable Lady Gust, will remain for future observa- 

 tions to verify. This variety was found by Mr. Walker at 

 Llandrillo, in 1879. 



Among the specimens brought home by myself on this 

 occasion (July 11th, 1885), was one which I was quite 

 unable, after repeated endeavours, to identify with any of the 

 varieties of this most protean species described by Gosse. 

 This form is so very distinct that I have ventured to append 

 a description and a figure of it, and since it possesses a disc 

 of the purest white, I propose the name of var. Candida 

 for it. The following is a description taken from the 

 specimen during life. 



Cylista uiidata, Miill., var. candid>a, nov. (see PI. II, figs. 

 3 and 4). 



Column. — Capable of great elongation, pale drab, with 

 darker longitudinal lines at the base, disappearing at about 

 half the height. 



Disc. — Pure opaque white, the radii not indicated ; the 

 extreme margin of the disc is translucent deep purple. 



Mouth. — Concolorous with the disc, slightly elevated on 

 a cone. 



Tentacles. — Not very numerous, in about five rows, the 

 inner ones being longest. All are pellucid grey, tipped with 

 opaque white ; the inner row, six in number, have a dark 

 purple longitudinal stripe on the face and back; the 

 remainder have similar stripes of scarlet, the whole of the 

 base of the tentacle being sufi*used with the same colour as 

 the stripe. Near the foot of the inner tentacles only, is a 

 faintly indicated dark cloud representing the B mark of the 

 typical form of this species.
