 fam. 3, pi. 35. 



Body yellowish- white or purplish, with orange spots : dor- 

 sal tentacles rather long, white below and orange above : oral 

 tentacles shortish, pale orange: branchial processes ovate-oblong, 

 inflated, yellowish-white, or occasionally lilac on the surface, 

 with the central gland of a pale strawcolour ; the tips have 

 a ring of bright orange ; they are set in 9 or 10 rows : foot 

 nearly linear, with the front angles rounded. L. 0-5. 



Habitat : Malahide, near Dublin (Alder); Burghead (Mur- 

 ray) ; St. Andrews (M'Intosh). [North of France (Quatre- 

 fages, as Amphorina Alberti).~] 



This is rather a rare species. A single individual only was 

 dredged at Malahide, which was nearly colourless, excepting 

 the orange spots and rings ; but several specimens have since 

 been found at Burghead by Mr. Murray with more or less of 

 a purple or lilac hue on the surface. This variety appears to 

 be what is described under the name of E. Andreapolis by Dr. 

 M'Intosh.

Body rather slender, pellucid orange-red : dorsal tentacles 

 rather long, smooth, orange-red, with yellow tips, having a 

 pale space on each side of the back behind, on which the eyes 

 are placed : oral tentacles a little shorter than the dorsal pair 

 and of the same colour: branchial processes elliptical, inflated, of 

 the same colour as the body, but deeper towards the tips ; the 

 central gland is yellowish ; they are set in 12 or 13 transverse 

 rows : foot tinged with orange-red, truncated in front, with 

 the angles rounded. L. 0-5. 



Habitat : Dredged in Weymouth Bay [in 6 f., feeding on 

 Plumuluria~] by Mr. Wm. Thompson. The species varies in 

 intensity of colour, the first observed being nearly white. E. 

 Robertiance of Dr. M'Intosh, St. Andrews, is a variety of this.
