ANALYSIS AND DISTRIBUTION OF TYPES OF CALICLES. 283 
P. Great Barrier Reef 36. The walls convex, with a faint median keel (see also 
b, iii.). 
P. Great Barrier Reef 37, ~ With wall either a stout and filamentous, or slightly 
flaky reticulum. 
P. North-East Australia 1, With walls regularly reticular or solid looking and 
flaky. The pali rise irregularly to some height, and may be joined to the 
wall by septal bars. 
P. North-West Australia 4. See C a for the topmost calicles; round the edges, 
broad flat irregular walls are striated irregularly. 
North-West Australia 6. The flat-topped walls with irregular margins and 
a loose system of branching filaments striating their tops. 
Philippines 5. With walls as a very simple open network in which the 
different skeletal elements can be easily traced. 
China Sea 5. With bold, open and flaky wall, having a slight ridge. The 
horizontal elements are stout and the trabeculze irregular. 
P. China Sea 6, passes from 3, iii. to this sub-division on all eminences where the 
walls thicken. 
P. China Sea 8 With rounded solid-looking walls, minute jagged points 
marking the rings of the component trabecule; a very large palic ring 
flush with the walls. 
P. China Sea 11. With rounded solid walls, having straight, median rows of 
frosted granules, with regular rings of similar granules on the inner 
margins, and regular pali, all flush with the walls. See also C, a. 
China Sea 13. With flaky walls rising to a ridge, but wall- and septal 
granules are indistinguishable. 
China Sea 14. With very tall walls, single or reticular, and surging up into 
ramparts. Septal and wall trabecule confused and indistinguishable. 
Ceylon 12. With flat-topped walls with scattered granules and very irregular 
inner margins. 
P. Maldives 1, Walls either a light network, or very thin and membranous 
with inner ring (see J, i.). 
P. Rodriguez 1. The reticular network of the wall is level-topped and varies 
in thickness. The pali are very pronounced. 
P. Rodriguez 2. A reticular network over the top of the stock. At the sides 
as in 6, ii1., with walls thin. 
P. Red Sea 5. Walls flaky, smooth, or striated.

b, v. The septal trabecule are partially wanting. 
P. Tonga Islands 4. Already mentioned in C,a. In parts the septal trabeculie 
only seen in angles of the polygonal calicles. 
P. Tonga Islands &§. With walls thin, membranous, and ragged. The septal 
trabeculz very feebly developed. Pali flaky. 
P. Fiji Islands 18. With Wall stout and sharp-edged; septal strive slope 
steeply down; cf. also 4, iii. 
P. Fiji Islands 20. With wall stout and sharp-edged; septa spring out at 
right angles towards the pali.
