100 ETEONE PICTA. 



below the gut in Eteone foliosa, De Quatrefages, and apparently in the line between the 

 feet (as it is not figured). 



In May (1903) Leschke found larvse of Eteone in the Bay of Kiel. 



1. Eteone picta, De Quatrefages, 1865. Plate XLV, fig. 3; Plate LXIX, figs. 3 and 4— 



feet; Plate LXXVII, fig. 22— bristle. 



Specific Characters. — Head pale, flattened, shovel-shaped, with an evident constriction 

 opposite the eyes, in front of the swellings from which the tentacular cirri arise, and 

 another a little behind the tip. Eyes black, situated rather near each other at the 

 posterior third of the Tiead. Four short tentacles are attached anteriorly. Two subulate 

 and short tentacular cirri, which are less than the transverse diameter of the head (in pre- 

 servation). Body from one to three inches long, firm, somewhat flattened, gently dilating 

 behind the head, and again diminishing a little towards the tail, where it ends in two 

 ovoid yellowish cirri. Ground- colour pale yellowish, and each segment laterally has a 

 reddish-brown or rose-red spot opposite the foot, and two others on each side of the 

 middle line. Thus there are four rows in addition to the spots on the dorsal cirri. A 

 patch of yellowish pigment occurs between the foregoing spots in the anterior third of the 

 body. The posterior third is in some pinkish — apparently from the ova. Dorsal cirrus 

 broadly lanceolate or somewhat conical, and firmly fixed to the peduncle by almost the 

 entire base. Setigerous process is bifid and comparatively short. The shaft of the stout 

 bristle is dilated, and, antero-posteriorly, has two hook-like spines of large size (laterally a 

 median curved spine and a smaller in front and behind). The terminal serrated blade is 

 comparatively short, broad at the base, and rapidly tapered to a fine point. Ventral 

 cirrus bluntly lanceolate, reaching almost to the tip of the setigerous process, but 

 shrinking within it at the fiftieth foot. It is borne on a distinct basal process (cerato- 

 phore) which projects from the setigerous lobe of the foot.

 Guernsey and Herm ; Whitby (Dr. Carrington) ; deep water off St. Andrews Bay, and 

 in the stomach of the cod and haddock, St. Andrews (E. M.).
