part diminishes somewhat in dionminenes viDR it is pro- 
duced into the proboscis. 
The proboscis is cylindrical in form, about 64”” long, 
and 5”” thick at origin, fig. 21, c, but eradually expands 
to 97”. near the anterior extremity, fig. 21, d; here, 3 or 
4”” from the tentacular collar,’ it becomes a trifle slenderer, 
constituting a kind of neck, fig. 21, e, and terminates in å 
coniparatively broad, arcuate disk, somewhat like the oral 
disk of an Actinia, fig. 21, Hy Dm the middle of which is 
the round buccal aperture, figs. 21; 22, b, the greater 
part of the peripheral margin being taken up: by the ten- 
tacles, figs. 21, g; 22, c. 
The position of the tentacles on the ‘buceal disk is 
peculiar, the collar itself being remarkably waved, forming 
as it does a series of undulations, 10 long (festoons) and 
10 short, figs. 22; 23. ; 
The long undulations extend far out on the buccal. 
disk. Each of these festoons is studded along its two 
margins with tentacles, 8 on either margin, figs. 22: 23, a, 
The 4 innermost 
tentacles. are the largest; the others dimmish considerably | 
in size, the two outermost being comparatively small, and 
when the whole assemblage forming the collar are not fully 
exserted, seemingly placed on the margin of the nearest 
short undulation, fig. 23. 
The 10 short undulations are strictly continuations 
of the large ones, but reaching very little, within the mar- 
_ gin of the oral disk, and furnished with only two tentacles 
each, fig. 23, b, in magnitude equal to the fifth (counting 
from within) of those forming the festoons.
