Habitat. — Under stones near low water-mark amongst the rocks, and from the debris 

 of the lines from deep water, St. Andrews (E.M.) ; Outer Hebrides (Lochmaddy), both 

 between tide-marks and in the Laminarian region, and Sound of Harris ; on shells from 

 deep water off the Channel Islands ; as well as between layers of rock near low- water 

 mark (W. C. M.). In 80 fathoms, St. Magnus Bay, Shetland (J. G. J.). On greyish 

 sand, stones, and coral at 164 fathoms in the ' Porcupine ' Expedition of 1869. A species 

 abundant in both tidal and deep waters all round the British shores. 



It extends to the Baltic, Norway, and Finmark. 



Head (Plate XLIII, fig. 9) rounded, cordate, broader than long ; pale, or with a slightly 

 pinkish hue, straw-coloured or greenish, the large black or brownish black eyes thus being 

 prominent, and they apparently enlarge in ripe examples. Anterior tentacles of moderate 

 length and subulate ; the median, somewhat shorter, arises in front of the eyes. The 

 tentacular cirri are also of moderate length, the dorsal in each pair being the longer, 

 and all taper from the base to the filiform tip, which in the posterior pair is more finely 

 attenuate. The ventral of the second pair is broader and slightly flattened, approaching 

 a narrow, lanceolate form. As in Eulalia the first pair springs from what (Ersted termed 

 the base of the head, but which probably represents a fused peristomial region, the 

 second and third from the following segment, which is united with the former, and the 

 fourth from the succeeding segment, a rudimentary foot (as in Eulalia viridis) being 

 beneath it. In some a pale area intervenes between the eyes, and occasionally a few 

 white grains are found in the same region. In several from St. Peter Port, Guernsey, 

 the tentacular cirri, opposite the white post-cephalic belt, were white. 



Body 1^ to 2-| inches in length, of considerable proportional bulk, soft and
