Habitat. — Dredged in fifteen fathoms off Fermain Bay, Guernsey, on shell-gravel, and 

 also procured between tide-marks, St. Peter Port (W. C. M.). Off the Hebrides and off 

 Inverary; in 160 fathoms, fifty-five miles Avest of Valentia, Ireland (J. G. Jeffreys). In 

 seventy-five fathoms on mud with stones and mussel-shells — ' Porcupine,' 1869 — 

 Station XXXIV; and in 80 — 110 fathoms on muddy sand with pebbles in the same 

 Expedition. Very fine examples are procured between tide-marks, Herm. S.W. Ireland, 

 log 56 (H. I. A. Expedition). Jersey (Hornell). 



St. Vincent, Cape Verde Islands ('Challenger'). St. Malo, Isles de Chausey, Dinard, 

 and other shores of France (De Quatrefages, De St. Joseph). Off Cape Guardia, and in 

 eighty-one fathoms off Cape Finisterre, ' Porcupine ' Expedition, 1870. 



Head bilobed anteriorly from the great palpi, comparatively small and crowded with 

 the five tentacles, the median being the longest. The ground colour of the tentacles 

 is dull yellow, with olive-brown bars. These organs do not taper much and seem to be 

 proportionally thick, slight constrictions occurring at the olive-brown rings, which are 

 five in number on the median tentacle, the most distinct being at the terminal ring. 

 Minute white grains also occur on the tentacles. Behind the median tentacle are two 

 white spots on the head and one in front of it. A few others occur near the base of the 

 lateral. A well-marked eye lies externally at the base of the inner lateral tentacle and 

 behind the shorter external tentacle. 1 The prominent posterior edge of the cephalic 

 segment is dark brown, and the slope of the ridge light brown, the whole defining the 

 region very distinctly. 



Body 6 to 9 ins. in length, rounded in extension, flattened in contraction, and of a 

 fine pale brownish-red colour, with a dorsal streak from the blood-vessel, and variegated 

 with regular white markings. It is slightly tapered anteriorly, and distinctly so pos- 



1 A careful account of the minute structure of the eye of this form and of other annelids is given 

 by Von Graber, ' Arch, f . Micros. Anat,/ xvii, p. 243, pis. 28—30.
