AGGREGATE FORM: Six Specimens examined 
with length range of 4-13 mm. without pro- 
jections (Fig. 27). The figures of Traustedt 
(1893), and especially Tokioka’s descriptions 
and figures (1938), are excellent. The tentacles 
of this form are at most three, usually two. 
In addition, however, there are attachment 
organs that Sewell (1926) considered tenta- 
cles; this error was corrected by Thompson 
(1948). TesL' Stiff, thick in all areas, especially 
on chin and gut swelling; mantle often far 
separated from test dorsally; weak dorsal ele- 
vation extending from base of cloacal flap 
to base of dorsal lip, limited by transverse 
grooves at these places; cloacal flap very large; 
laterodorsally, a bulging limiting elevation on 
each side of dorsal elevation, continuous to 
chin and posteriorly forming tentacle; ten- 
tacles three in young specimens: two lateral 
posterior, and one median posterior projecting
