7. EOLIS CONSPEBSA The Sprinkled Eolis. Plate XLIV. Figs. 13, 14. 



Length above four lines ; breadth a line. Tentacula and cornicula 

 rather stout, and nearly equally long. A black speck at the base of each 

 corniculum. Back bare, bordered by several branchial clusters of elon- 

 gated ovoidal papillge, neither so numerous, nor so definitely clustered, 

 as in other species with similar clusters. Upper surface universally pale 

 yellow. Clusters olive brown, sprinkled with white tips, and roots of the 

 papillse lighter. Cornicula of one specimen tipped with yellow. This 

 animal is very rare.

8. EOLIS INEQUALIS. Plate XLIV. Figs. 15, 16. 



The chief characteristic of this species consists in the irregularity of 

 its parts, both in size and distribution. 



Length fifteen lines, breadth four. Head somewhat round. Shoulder 

 rounded, body tapering downwards. Mouth wide, amidst thick lips in 

 the face below. The cornicula are longer than the tentacula. They 

 seem to fork from a short pillar rising on the surface of the neck. A 

 dark speck on the neck, at each side of the cornicula. Middle of the 

 back bare. The branchial papillae, of very unequal dimensions, are scat- 

 tered irregularly over the rest of it, not obviously in clusters, but more 

 profusely on the shoulders. Colour of the body pale blue and dingy 

 white ; extremities of the papillas vivid yellow, centre dark. 



Two specimens exhibited the same general features. The second 

 was about half the size of the first. A third specimen from the Mar 

 Bank, as I concluded, on 22d March 1850, extended about eight lines ; 

 the branchial papillae numerous, and rather disposed in tufts : only a 

 few of them were tipped with yellow. The animal, originally weak, 

 survived but a short time.
