iu number) are in a new field, — one being a new species, viz., Eolis 
Lochmaddii : — Body^ rather more than a quarter of an inch in 
length, pale, translucent, and faintly pinkish on dorsum from 
viscera. Tail., stretching a little beyond the sloped branchise, pale. 
Oral tentacles, pale, rather short. Dorsal tentacles, generally carried 
erect, thick, coarsely crenulate, barred with pink, and white at tips. 
Eyes, distinct. Branchiae, at first small and club-shaped, then 
becoming long and slightly fusiform ; processes bent inwards over 
the dorsum, and tapered towards the tips. Colour, pale pink, grained 
with red ; tips with white grains and a few red, capped by a trans- 
lucent point. It is an active and hardy nudibranch, swimming on 
the surface, elongating its foot, and throwing it into a goove. It 
deposited* pale pink ova, as a simple band in transparent mucus. 
In the loch, the hard and muddy ground abounded in small 
cockles, Venus ovata, Grenella decussata, Corhula nucleus, and occa- 
sionally the rare Lima suhauriculata. The most common univalves 
brought in by the dredge (from four to fifteen fathoms) were Trochi, 
Lacunm, Eissom, and the curious species resembling Alcera hullata, 
but possessing two distinct eyes ; the latter animal preferring a hard 
bottom, not far from mud. Thracia distorta and dead valves of 
Thracia convexa were got in company with Tellina donacina, Venus 
casina, and Artemis exoleta in the same region. The valves of the 
Pecten maximus, cast on shore by winter storms, are still used by 
the natives for skimming milk and scooping butter. On the 
western shores of the island the pretty Phasianella pullus is com- 
mon. Sepiola atlantica was dredged also at Paible, on sandy ground. 
A purplish-brown variety of Elysia viridis, with many pink and 
blue specks, was frequently got at Lochmaddy.
