BRITISH NUDIBRANCHIATE MOLLUSCA. ix 



of the papillae branched. On the shore of the Holy Isle in the same bay, we got a specimen 

 seven eighths of an inch long, entirely white ; and two others, smaller, which had the branchiae 

 yellowish, spotted with brown, and brown rings at the tips : the body was marked with brown 

 bands similar to those described above. 



Professor Loven has found Eolis alba in Norway. He remarks of it, " Branchiae in meis 

 saepius testaceae, niveo-punctatae, sed media decolorantur." 



(24) EOLIS CARNEA. 



In 1 843, we received a specimen of this Eolis in spirits from Mrs. Wyatt, of Torquay, 

 who had dredged it in Salcombe Bay. We deferred publishing it, hoping to have met with 

 it in a living state, but in this we have been disappointed. The species is interesting on 

 account of its close relationship to K alba, having the same arrangement of the branchiae in 

 imperfect clusters or double rows anteriorly, as well as the dark dorsal tentacles. We could 

 not ascertain that these latter had the bulbous swelling, but this character usually disappears 

 in spirits. The tongue has a single plain spine in each row as in U. alba. The specimen 

 examined when recent (in spirits) had the body of a pale rose- or flesh-colour, long and slender. 

 The branchiae were rose-red, rather conical, and set in seven clusters, the three anterior ones 

 containing two rows each (five or six papillae in each row) ; the others were in single series. 

 The first cluster approached close to the dorsal tentacles. These tentacles were plain, slightly 

 conical, dark olive-brown, or nearly black, paler above, and approximating at the base. The 

 oral tentacles were about the same length as the dorsal pair, transparent white, tapering to a 

 point. Foot slightly bilobed in front, the angles produced into very long tentacular points at 

 the sides. 



We are now inclined to refer the Eolidia Cuvierii of Johnston, found in Berwick Bay 

 (Ann. Nat. Hist., v. 1, p. 120, pi. 3, figs. 9 — 11), to this species, which has the branchiae arranged 

 much in the same manner. The dorsal tentacles, however, are not so dark-coloured ; they 

 are called "olivaceous with yellowish tips." However the case maybe, we do not think that 

 Dr. Johnston's animal can be the " Eolide" described by Cuvier {JEolis Cuvieri, Lam.) ; a 

 species that it would be difficult now to identify, and which has been much misunderstood by 

 French writers. 



In this state of uncertainty concerning the Berwick specimen, we do not feel inclined to 

 give it a separate place in our list. The JEolis Cuvierii of Macgillivray appears to be some- 

 thing different that we cannot make out.

 Hab. Under a stone near low-water mark, Torquay, J. A. 



Body rather less than half an inch in length, ovate, and rather flattish, pale fawn-coloured, 

 or nearly white. Dorsal tentacles short and stout, yellowish, slightly wrinkled ; eyes large 

 and conspicuous at their posterior base. Oral tentacles short, white, about equal in length 

 to the dorsal pair. Branchiae cylindrical, tapering a little and obtusely pointed, of a dull
