Body rather small, ovate-oblong, attenuate posteriorly. Lateral tentacles fixed 

 under the median, head deeply incised in front, and with prominent lateral peaks. 

 Eyes four, generally large, the anterior pair on the projecting lateral region; 

 the posterior in front of the nuchal collar and widely separated. Palpi densely 

 covered with minute papillae. Scales, fifteen pairs, spinulose, ciliated or smooth 

 at the edge. Dorsal bristles shorter than the ventral, and with wide rows of spines ; 

 ventral bristles very long, with minutely bifid tips. Segmental papillae well marked, 

 but not long. 



1. Evarne impar, Johnston, 1839. Plate XXYI, fig. 5. 



Specific Characters. — Head wider than long, with prominent peaks anteriorly. Eyes 

 large ; posterior pair in front of nuchal collar, widely apart ; anterior pair on projecting 

 lateral region. Median tentacle strong and moderately long, densely ciliated, madder- 

 brown, with a slightly dilated whitish region, marked off by bars, below the filiform tip. 

 Lateral tentacles inferior, subulate and tapering, with short clavate cilia. Tentacular 

 cirri similar to, but more slender than, the median tentacle. Palpi of average length, 

 with tapered extremities, and densely covered with minute clavate papillae. Body some- 

 what thin and flattened, broadest at the anterior third, thence tapering to the tail. 

 Segments thirty-eight to forty, greenish-brown on the dorsum, darkest in front, the pigment 

 forming somewhat regular bars and touches. Arch of pigment in the cirrigerous seg- 

 ments terminates laterally in two small touches of dark olive, besides other touches at 

 base of cirri. Ventral surface pale or brownish. Segmental eminence and papilla well 

 developed, commencing on the sixth bristled segment. Two long caudal styles. Scales, 

 fifteen pairs, mottled with brownish pigment, often with a yellowish speck in the centre. 

 First pair subcircular, rest renif orm and then ovoid ; external margin densely ciliated ; 

 surface mostly covered with small horny papillae, with larger ones towards the outer 

 and posterior borders, while along the latter are a few large pyriform or globular papillas. 

 Dorsal bristles translucent, rather acutely pointed, with wide rows of spines which cross 

 the shaft at right angles; ventral bristles with elongate tapering spinous regions and 

 minutely bifid tips ; the latter diminish in length inferiorly, and some at the ventral edge 

 have simple tips. Dorsal cirri like tentacular cirri; ventral cirri subulate, the slender 

 tips reaching the ventral bristles, and with numerous short clavate cilia.
