EUPHROSYNE. 127 



Hab. Coast of Ireland, and of the south of England. " Aug. 26, 

 1 844. — A very handsome Aphrodite-lookmg species, dredged today 

 by Mr. Hyndman off Castle Chichester, Belfast Bay, was brought 

 to me. It was taken about a mile from the shore on shelly ground, 

 in from six to ten fathoms water." " The specimen is an inch in 

 length ; the size attributed to the species by M. -Edwards. Two 

 others, differing only in being smaller, were last year purchased 

 by Mr. R. Ball (of M'Calle), but it was not stated on what part 

 of the coast they were procured." — W. Thompson. "Weymouth 

 Bay, P. H. Gosse. 



Besc. " The minute antenna at the tip of the caruncle appears to 

 be flattened and truncate, instead of subulate ; and the colours of 

 the little animal are less vivid than those ascribed by its learned 

 describers to E.foliosa. I should designate the hue of my specimen 

 a bright cinnamon-red, rather than cinnabar, and the median line of 

 the ventral surface is purplish. Its length is three-quarters of an 

 inch." — P. H. Gosse. 



2. E. borealis, body ovate-oblong, yellowish, hirsute; segments 

 26 or 27 ; caruncle elongate-oval ; antenna one, semiglobose ; 

 branchiae 9-10, bi- and tri-partite ; dorsal cirrus none. Length ;|".

Hab, Coast of Scotland? The specimen was found in a bottle of 

 miscellaneous avertebrates given to me as British by R. M*An- 

 drew, Esq. 



Obs. The specimen in spirits is of a uniform cinereous colour. 

 Its external appearance is so very similar to Spinther oniscoldesy 

 that their identity may be questioned. There are several particu- 

 lars, however, in which the two worms differ so much, that I can 

 only suggest my suspicion to lead to further inquiry. I have not 

 seen a second specimen of the Spinther ; and I must content myself 

 with reproducing the original description without any alteration : —

Hab. Belfast Bay, in six to ten fathoms. 



Desc. Body ovate or oblong, convex dorsally, flat and perlaceous 

 on the ventral surface, of a uniform cream-yellow colour, rounded 

 and obtuse at both extremities, which are so much alike, that, with- 

 out a close examination, the anterior is not to be distinguished from 

 the posterior. There is no head, tentacula, nor tentacular cirri. 

 With a common magnifier we perceive that the back is crossed by 

 numerous (about 30) narrow roughish edges (fig. 8), the roughness 

 being produced by a series of minute bristles which scarcely protrude
