EOLIS* ANGULATA; Alder and Hancock. 



E. subangulata, depressa,, pallida auran'tiaca : branchiis cylindricis, aurantiacis, albo maculatis; 

 tentaculis brevibus; angulis pedis acutis. 



Eolis angulata, AM.and" : Hanc! in Ann. Nat. Hist. v. 13,, p. 165. 

 Hab. On a stone/from, the/ fishing boats, Cullercoats. 



Body about four lines long, depressed, subangulated, broad in front, and terminating 

 rather abruptly behind, of a pale pellucid orange colour. Dorsal tentacles short, conical, 

 obtuse, orange tipped with white; set a little apart and only slightly inclined forwards. 

 Oral tentacles rather longer than the dorsal ones, nearly linear, rather obtuse, the lower 

 portion transparent, the rest of an opake white. The eyes are very large, and placed a little 

 behind the dorsal tentacles. Branchiae cylindrical, rather long, slightly elliptical, obtusely 

 pointed, orange-coloured with white apices ; the surface covered with opake white blotches. 

 The central vessel is slightly granular and nearly fills the sheath, except at the top, the 

 points extending considerably beyond it. They are arranged along the sides in ten or 

 twelve close-set, but well-defined, rows of four or five papillae each, leaving a broad space on 

 the back. Foot broad, transparent, and delicately tinged with orange. It extends only a 

 short way beyond the branchiae behind, where it suddenly tapers to a fine point : it is broad 

 in front and produced into lengthened angles at the sides. 



A single specimen of this species was obtained from a stone brought in by the fishermen 

 at Cullercoats, probably from deepish water. It lived several days, and moved about with 

 much ease and rapidity, swimming at the surface of the water much more quickly than 

 usual.
