metamorphosed, adult, sessile feeder, is placed 
in serious doubt. Perhaps the pleotelson, acting 
as a bulkhead, blocks the easy access of nega- 
tively phototropic swimmers and provides a 
suitable surface for lorica formation. But to 
date, this is mere conjecture. Only about 50% 
of the lorica had extensive lateral pouches. 
The peristomal lobes (a) are without finger- 
like projections but, as mentioned by Silen 
(1947:59) are frequently bent forward. The 
nucleus (^) is always moniliform, although the 
number and size of beads vary considerably. 
The foot (/) is non-spatulate. 
The color varies according to the amount 
and distribution of pigment grains, but in 
general it is a light, almost grey-green. The 
peristomal lobes when extended often appeal 
rosy-pink.
