REPORT ON THE ANNELIDA. 
97 
widely separated eyes posteriorly, and a larger pair situated on the anterior lateral 
prominence. The tentacle is absent. The antennae are subulate and brownish, with a 
filamentous tip. The dorsal cirri have a characteristic fusiform appearance, from the 
gradual nature of the dilatation and the long filiform tip. They are sparsely covered 
with clavate cilia which in length barely attain three -fourths the diameter of the thickest 
part of the cirrus. The ventral cirri are rather slender and small, and also possess a few 
short clavate cilia. 
The scales seem to be fifteen pairs. The smaller first pair are rounded, and studded 
with tubercles and minute spines. The latter occur along the anterior border, while the 
larger are scattered over the outer and posterior areas, in the form of low blunt 
processes, five or six along the posterior border being very large. The scales are thin 
and translucent, and thus show all the markings clearly. The border is quite smooth 
throughout. The scales from the middle of the body have the greater part of the surface 
covered with small tubercles, while the isolated large blunt conical forms occur within the 
posterior border and neighbourhood, a few^' intermediate kinds being situated within the 
outer border. The scales are mottled with touches of brown, best marked round the 
area of attachment. 
The brownish pigment of the dorsum of the body posteriorly is very prettily 
arranged in lozenges and touches, as often seen in species of Lagisca. 
Evarne, Malmgren. 
Evarne kerguelensis, n. sp. (PL VI. fig. 4; PI. XIX. fig. 6; PI. VIa. figs. 12—14). 
Habitat. — One example was procured by the dredge at Station 149e (Kerguelen 
Island, off Greenland Harbour), January 21, 1874; lat. 49° 37' S., long. 70° 16' E.; 
depth, 30 fathoms; volcanic mud. 
Many others were obtained amongst the bristles of Lcetmonice producta, dredged 
off Christmas Harbour in the same region, January 29, 1874; depth, 127 fathoms. 
This new form, when compared with the well-known Evarne impar, Johnston, from 
Europe, is smaller, and the feet and bristles are proportionally shorter, thus giving the 
body to the naked eye a firmer appearance and more defined outline. The brown pig- 
ment of the dorsum (after removal of the scales) is also in a large and more uniform 
transverse bar in each segment. The length of the larger form is about 13 mm. and 
the breadth about 4 mm., whereas a good example of the British Evarne impar 
measures from 18 to 20 mm., and has a transverse diameter of 7 or 8 mm. 
The head has considerably smaller eyes than Evarne impar, but they hold the 
same position. The tentacle shows more evident cilia, a feature, however, only apparent, 
and due to the presence of parasitic growths. The organ has a longer filiform tip than
