Folliculinids from Submerged Wood-— MATTHEWS

The diameter of the neck was almost uniformly 
50 fiy except for those of certain empty loricae 
whose necks were ellipsoidal; in such instances 
the greater diameter ( at right angle to the longi- 
tudinal axis) was roughly 58 /x and the lesser 
diameter 2 5 /a. 
The greatest variation was observed in the 
number, arrangement, and size of the lateral 
pouches (Figs. 2 A, B; 3 A t B; 5 A, B; 6). Al- 
though smaller loricae usually exhibited fewer 
pouches, this was not always the case. For ex- 
ample, a lorica (Fig. 5 A) with but 6 pouches 
( the smallest number observed ) was larger than 
a lorica (Fig. 5 B) with 16 pouches. (Nineteen 
was the largest number observed. ) 
Although each lorica was somewhat swollen 
at its base, the pouches did not necessarily ex- 
tend, as did those shown by Giard (Fig. 2 A, 
B ) , in finger-like protrusions from the swollen 
base, nor were they bilaterally arranged. Ar- 
rangement of pouches varied from as few as 2 
pouches on one side and 4 on the other (Fig. 
5 A) to as many as 9 on one side and 10 on the 
other (Fig. 6). Figure 5 B is interesting for 
not only does it show a bilaterally symmetrical 
arrangement of the 16 pouches, but the anterior 
2 (a) are dearly seen through the neck when 
viewed dorsally; hence similar outpocketings (as 
.66 mm.

in Fig. 6a) may have been mistaken for the so- 
called valves mentioned by earlier investigators. 
Even more variable was the size of the lateral 
pouches. These ranged from only a few microns 
(Fig. 6b) to half the width of lorica (Fig. 5 A, 
c ). And, although large pouches were usually 
located posteriorly near the base of the lorica, 
occasionally they were located anteriorly near 
the neck. Because to my knowledge the process 
of lorica formation in this species has not been 
observed, neither pouches nor their variation in 
number, arrangement, and size can at present 
be explained. 
Unfortunately, too many observers have been 
concerned with the unique lorica and too few 
with the living organism. Even actual descrip- 
tions are meager. Giard '( 1888:315), who at- 
tributed to this species a non-moniliform nu- 
cleus (Fig. 2 By a) merely states . . [it] is a 
little smaller than the preceeding species { Fol - 
liculina abyssorum Giard], of a darker greenish 
blue with the striation of the integument less 
apparent. . . Kahl ( 1932 ) is concerned that
