342 HARMOTHOE LUNULATA. 



9. Harmothoe lunulata, Belle Chiaje, 1841. 



Specific Characters. — The head approaches that of Harmothoe marphysse, only it is 

 less elongated and the eyes are larger. The tentacles and tentacular cirri are brownish ; 

 palpi smooth. Body about three quarters of an inch long ; ventrally, with a series of 

 brown spots, which, as a rule, commence as four rows somewhat behind the middle. 

 Occasionally by union they form bars at the junction of each segment. A prominent 

 segmental eminence and papilla. Scales fifteen pairs, smooth round the margin, but 

 with a dense cluster of minute horny papillae on an area in front of the scar. Brown 

 pigment variously arranged— some having a ring of brown or a V-shaped pattern on the 

 scale, while the outline of the pigment in others has the shape of the shell of Pandora. 

 Dorsal bristles are better developed than in H. marphysse., being long, tapering, slightly 

 curved, and finely spinous. The ventral bristles, again, form a fan, and the tips of 

 almost all have a secondary process. The dorsal cirri are comparatively short tapering 

 organs, with sparsely distributed short clavate cilia. The ventral cirri have similar cilia, 

 and are slender, their tips reaching beyond the base of the nearest bristles.

Habitat. — Yery generally distributed throughout British waters— from Shetland to 

 the Channel Islands, and from the west coast of Ireland to the east coast of Scotland. 

 It ranges from the tidal rocks in the Channel Islands to 120 fathoms off the south-west 

 coast of Ireland. It extends to the Mediterranean. 



Head (Plate XXVII, fig. 8) resembles that of H. marphysse, only it is less elongated 

 and the eyes larger. The median tentacle is brownish, has a filiform tip and sparsely 

 distributed clavate cilia. The lateral tentacles are subulate, with a filiform tip and 

 clavate cilia. The tentacular cirri have the same form as the median tentacle, and also 

 the same brownish colour. The palpi are smooth. 



Body about three quarters of an inch in length, slightly tapered anteriorly, and 

 much more so posteriorly. The chief feature of moment is the presence, in the majority, 

 of a series of brown spots, which commence as four rows somewhat behind the middle. 

 In some the sets are united so as to form two rows of bars at the junction of each 

 segment ; and this confluence sometimes occurs posteriorly even when the four rows are 

 distinct in front. The segmental eminence is well marked, and a small cylindrical 

 papilla projects between the feet.
