ETEONE SPETZBERGENSIS. 105 



in size from before backward, and is nearly equally bifid, with a dorsal elevation 

 posteriorly. The dilated ends of the shafts of the bristles have two unequal spines, and a 

 spinigerous ridge on each side. Terminal blade broad inferiorly, tapers to a fine point, 

 and has a serrated edge. The ventral cirrus is oblong-ovate at the tenth foot, and 

 gradually increases in transverse diameter from this region backward. Its outer margin 

 projects a little beyond the tip of the setigerous process.

Fig. 44. — Head of Eteone spetsbergensis, from life. 



Head, (Fig. 44) somewhat elongated, separated dorsally from the peristomial 

 segment by converging lines, and bluntly rounded in front between the two short 

 tentacles, the upper of which is the shorter, and placed anterior to the other. The 

 tentacular cirri are also short, the inferior being the longer. In the preparation they are 

 about half the transverse diameter of the peristomial segment. Two pale eyes (woodcut) 

 occur at the posterior part of the head, but they disappear in spirit-preparations, in 

 which the head is also contracted into a short cone. 



Body three and a quarter inches long, about equally tapered anteriorly and posteriorly 

 (Malmgren), somewhat flattened, and with the segments marked in the typical manner. 

 The tail is incomplete, but Malmgren states that it bears two linear fusiform cirri. The 

 colour inclines to pale yellow anteriorly, especially in the lamellae, which are uniform in 

 tint throughout. After the first third the intestine gives the body a pinkish or skin colour. 

 The surface has a pearly iridescence, especially dorsally. The proboscis in extrusion is 

 clavate, with two median and two lateral rows of papillae, which begin as prominent organs, 

 and end distally in low transverse elevations. On the ventral aspect four longitudinal 

 bands are also present, but they have only low transverse folds or wrinkles. The aperture 

 of the organ is dorsal, and forms a papillose triangle. Gregarines w^ere common in the 

 intestine of that from St. Andrews. Several examples from Canada show in spirit a well- 

 marked brownish pigment-band within the bases of the feet on each side.
