three black spines support the foot. In the specimen only 
slightly brownish, long, tapering, winged bristles were 
present ; but as all the inferior were broken, their condition 
is uncertain (Pl. XII. fig. 33). 
About the 40th foot the posterior lobe or papilla becomes 
somewhat less, though of a similar outline, and the pale tips 
of the two black spines pierce a conical papilla anteriorly. 
Above the spines are two brownish winged tapering bristles 
as before, whilst beneath are three long hooks, the terminal 
winged region being rather short (Pl. XII. fig. 34). The 
crown of the hook is little developed and the main fang in 
this region is small; it probably increases in size posteriorly. 
The Lumbriconereis parva-pedata of A. lL. Treadwell * 
from Culebra comes near this form ; but as no description of 
the dental apparatus is given, the relationship is uncertain. 
2. On Canadian Eunicide dredged by Dr. Whiteaves, of 
the Canadian Geological Survey, in 1871-1873. 
Three species of Onuphididz were procured: one, Onuphis 
conchilega, Sars (the O. hyperborea of Hansen), occurred 
in considerable abundance in 125 fathoms off Cape Rosier 
Lighthouse in the Gulf of St. Lawrence in 1871, and also 
on Orphan Bank in 1873. As a rule, the branchize com- 
menced on the llth foot. The tubes are composed of 
coarse gravel and flat fragments of Echinoids firmly fixed 
to the tough lining of secretion. Those from Orphan 
Bank are smaller and the fragments composing the tubes 
less coarse. 
Onuphis quadricuspis, Sars +. 
Dredged in 150 fathoms off Cape Rosier Lighthouse, Gulf 
of St. Lawrence, 1871, and between Cape Rosier and Cape 
Gaspé in 75 to 80 fathoms on a stony bottom, in 1872. 
The head generally resembles that of other forms, but is 
eyeless in the preparations. The frontal tentacles are small 
and ovoid in outline. A patch of pigment occurs in the 
middle line posteriorly. The palpi form two prominent 
bosses inferiorly. The ceratophores of the tentacles are 
ringed, and the median is considerably shorter than the 
adjoining lateral.
