near Port Stephens, Australia, and Lepidonotus smiplicipes, from Griffith’s Point, 
Western Port, have no dorsal bristles, while Polynoe ochthoebolepis, from the Queensland 
coast, has nothing else than a tubercle. There does not seem to be anything else in 
common. His Polynoe asterolepis, from Torres Strait, again, has only a spine in the 
dorsal division.

Eulepis ivyvillei, n. sp. (PI. XIX. fig. 11 ; PI. XX. figs. 2, 3 ; PI. XXIV. figs. 2, 3 ; 
PI. XXV. fig. 11 ; PL XIVa. figs. 4-6 ; PI. XXXIIa. fig. 7). 
E[abitat. — A single example was dredged at Station 33 (off Bermuda), April 4, 
1873 ; lat. 32° 21' N., long. 64° 35' W.; depth, 435 fathoms; surface temperature, 68°'0 ; 
sea-bottom composed of coral mud. 
It is a stoutish form about 18 min. in length and 3 mm. in breadth. 
The body is elongated, slightly tetragonal, firm and tapered a little at either 
extremity. The dorsum is rendered irregular by the prominent processes for the scales, 
and the dorsal projections of the feet. The ventral surface, again, is flattened, and forms 
a plane somewhat below the level of the feet. The body terminates in a central anal 
papilla with the opening directed backward. 
The head is rounded and eyeless, marked only by central lines running back from the 
tentacle, which is a short conical j)rocess, somewhat enlarged at the base and with a 
bulbous tip. The long processes for the first pair of scales cover the greater part of the 
head posteriorly, leaving only the central region exposed anteriorly. On each side and a- 
little in front of the tentacle is a short and thick antenna, slightly tapered towards the 
tip. The relation of the three processes is therefore different from that in Eidepis 
hamifera, Grube.^ The palpi are comparatively short and gently tapered, with a linear 
ridge superiorly. They are smooth with the exception of a few very minute and often 
bifid papillae near the tapering extremity. The first pair of feet bear the tentacular cirri, 
the shorter inferior organs having a more distinctly bulbous tip than the more elongated 
superior. The ventral cirrus is somewhat elongated in front, but soon becomes short and 
bulbous, with a clavate terminal appendage. At the base of the foot, internal to the fore- 
going, is a tumid enlargement, which seems to be the homologue of that at the base of 
the ventral papilla in the Polynoidse. It forms the iDorder to the prominent ventral 
edge below the feet. The surface of each is dimpled, but the presence of an aperture is 
uncertain. A flattened branchial cirrus, again, occurs on the fifth segment, and a well- 
developed one on the seventh, and generally thereafter on each segment without a scule. 
It is terminated by a minute clavate tip, which would appear to indicate that morpbo-
