ment sites are not restrictive. In such instances, 
the lorica (Fig. 1 B, f) is only slightly dorso- 
ventrally flattened and appears to be only par- 
tially attached throughout its length by the 
collectoderm ( d ). Thus, a short free neck is 
held above the substratum. 
The length of the neck is difficult to measure 
since valves demarking neck from sac are absent. 
There are no longitudinal stripes, spiral whorls, 
rings, or extensions. 
The species is further characterized by peri- 
stomal lobes of unequal length and breadth; the 
left (Fig. 1 A, a and B, a ) is always broader and 
longer than the right (£). Moreover, the left 
(Fig. 1 B, a)i s usually held at right angles to 
the longitudinal axis, whereas the right ( b ) is 
usually held vertically. In the hundreds of speci- 
mens observed, no finger-like projections were 
seen on the peristomal lobes. 
The nucleus (c) is always spherical and ap- 
pears as a mass of rather large granules in the 
posterior half of the extended body. 
In specimens taken from restrictive areas 
(Fig. 1 A) the dorso-ventrally flattened lorica 
(/) accentuates the spatulate nature of the foot 
(Fig. 1 A, g), i.e., as the body contracts into a 
flattened lorica, the foot (g) is spread thinly 
into a broad spatula. Plowever, when the lorica 
is not so dorso-ventrally flattened, the contracted 
body has more space and the foot (Fig. 1 B, g) 
appears less spatulate. 
Color: light greenish-blue through grey to 
colorless.

Eufolliculina lignicola (Fig. 2) was first 
taken July 7, 1965 at Tatokushima from aban- 
doned bamboo poles of oyster rafts. Although 
the smooth, hard surface of the internodes af- 
fords little opportunity for heavy Limnoria sp. 
infestations, the nodes are riddled with their 
tortuous burrows and in these, but not restricted 
to them (see Matthews, 1963:438) were fully 
extended folliculinids. In every respect these 
resembled those obtained from Douglas fir 
( Pseudotsuga taxi folia) frames (Matthews,

1962). Again, sac length, width, and height 
vary with site conditions. Crowding usually 
results in an abnormally shaped lorica whose sac 
(/) (up to 170p) is often as long as the neck 
(r). And again, the neck, least affected by 
space restrictions, varies only between 130p and 
170p with 5-7 spiral whorls (d) . The nuclear 
components (c) vary widely; from what appears 
to be a more or less compact, spherical mass of 
5 or 6 large granules to a "broken” string of 12 
to 14 small beads. As in the Hawaiian repre- 
sentatives of this species, E. lignicola in Ago 
Bay is a deep wine-red in reflected light and
