 EOLIS VITTATA, Alder and Hancock. 



E. gracilis, fulva, maculis ferruginosis ; branchiis elongatis, sub-clavatis, pallide fulvis vel carneis, 

 cingulis 3 fuscis obscuris, apicibus flavidis, in seriebus 6-7 digestis ; tentaculis fulvo- annul atis, apicibus 

 albidis ; angulis anterioribus pedis obtusis.

Hab. On zoophytes from deep water, Cullercoats; rare. 



Body nearly four tenths of an inch long, slender, buff or fawn-coloured, with darker spots 

 and markings of the latter colour, especially on the head, and along the sides of the body at 

 the bases of the branchiae, where they form two broad interrupted lines. Dorsal tentacles rather 

 long, linear, slightly wrinkled ; fawn-coloured, with pale tips, and having a dull orange-coloured 

 ring two thirds up ; held nearly in an erect position. The eyes are placed at the base of these 

 tentacles, but in front of them, and not behind, as usual. Oral tentacles shorter than the dorsal 

 pair, coloured and banded in like manner, and inserted into the upper surface of the lip. 

 Head rather large, and truncated in front. Branchiae stout, long, and nearly linear, swelling a 

 little towards the apex, which is obtuse : they stand very erect on the sides of the back, and 

 radiate in the manner of the rays of a fan. They have the central gland of a rosy flesh-colour, 

 delicately freckled and granulated with darker rose-colour. Each papilla has three brown 

 bands, more or less distinct ; that at the top being usually strongest, and forming a ring round 

 the apex, which is pale yellow. The papillae are arranged in eight or nine transverse rows, 

 set considerably apart ; there are from three to seven papilla? in each row. Foot transparent 

 white ; the angles obtuse and not much produced. 



This beautiful animal has a considerable resemblance to F. cingulata, but the linear and 

 subclavate branchiae are sufficient to distinguish it. These never assume the ovate form of 

 that species, even when contracted ; their colour is also different. It may be remarked, too, 

 that F. vittata carries the dorsal tentacles more erect than F. cingulata. 



We have found three individuals of this species at different times on corallines brought in 

 on the lines of the Cullercoats fishermen. They were all more or less injured, a circumstance 

 unfortunately not uncommon, when these delicate and fragile creatures are obtained by that
