the length of the dorsal cirrus. At the twentieth foot (PI. XXXVIII. fig. 15) there are 
six branches, and most show the reddish-brown bodies formerly noticed ; moreover, 
these also occur in the dorsal cirrus, so that they are not peculiar to the branchiae. They 
are probably nucleated pigmentary bodies. The branchia*’of the thirtieth foot has five 
branches ; but on the fortieth it is represented only by a simple filament, almost as long 
as the cirrus, and the organ vanishes immediately afterwards (about the forty-first foot). 
The anterior feet have a dorsal cirrus of considerable length (a little shorter than the 
tentacular cirrus) and similarly segmented. A few simple bristles pass the branchial stem 
and enter its base. The ventral cirrus in this region is very large, forming a prominent

and broad horizontal lamella in all probability of considerable importance in regard to 
the habits of the species. The first six are about equal in size, the diminution only affect- 
ing the seventh. On the whole the inferior cirrus is well marked and large throughout. 
Dorsally is a tuft of long simple bristles (PI. XXa. fig. 4) somewhat like those with 
the serrated edge in Eunice cirrohranchiata. The brush-shaped forms (PI. XXa. fag. 5) 
have comparatively few (about five) short teeth, and the single long lateral process is 
stoutish. 'The jointed bristles (PI. XXa . fig. 6) show the usual bifid tip, neither process 
being long. It is serrated along the inferior edge. The tip of the shaft is also serrated 
and striated internally. The spines are yellowish and comparatively stout, the tips
