The above description from an individual found, in April, 

 1 842, by Mr. Leslie, among the rocks at Collieston.

2. JEolis Murrayana. Murray's JEolis. 



Body oblong, tapering behind to an obtuse point, convex 

 above, bare along the middle of the back, at its sides continu- 

 ously covered with very large oblongo-conical, round or some- 

 what compressed obtuse branchial papilla?, in several series ; 

 head depressed ; upper tentacula conical, obtuse, granulate ; 

 mouth proboscidiform, with a very thick external, circular 

 margin, a very thin inner, and opening by a vertical slit, 

 bounded by two large thin, anteriorly convex, horny plates ; 

 foot oblong, anteriorly abrupt, rounded at the angles, on the 

 margin waved, gradually narrowed, obtuse behind ; the back 

 bluish-white, with the papillae bluish-grey, the upper tentacula 

 rose-red, the mouth reddish-white, the foot white. Length 

 seven-twelfths of an inch. 



Found by Mr. Alexander Murray, in September, 1842, 

 under a stone, on the beach at St. Fergus; several specimens 

 also sent by him in December. 



In this species the papillae are larger and more closely set 

 than in iEolis papillosa, from which it differs further in having 

 the anterior angles of the foot rounded. Not finding a de- 

 scription exactly agreeing with it, T have named it as above. 



3. JEolis Cuvierii. Cuviers JEolis. 



Body slender, tapering behind to a fine point, convex above, 

 bare along the middle of the back, at its sides covered with 

 elongated tapering, obtuse papillae, arranged in transverse 

 series ; head depressed, somewhat truncate ; upper tentacula 

 elongated, subulate ; mouth with two long similar tentacula 

 on each side ; foot linear-oblong, slightly marginate, its an- 

 terior part acutely biangulate, or extended into tentacula ; 

 upper parts pale purplish or reddish-grey, the branchiae pink ; 

 the tentacula hyaline-white ; the foot reddish-white. Length 

 an inch and a-half. 



Two specimens found by me, in a pool among the rocks, at 

 Collieston, in April, 1842.
