ANALYSIS AND DISTRIBUTION OF TYPES OF CALICLES. 281 
P. Great Barrier Reef 19, The septal granules mostly as short, rounded flakes, 
projecting from the inner margin of the walls. 
P. Great Barrier Reef 24. With very broad, flat-topped, flaky, but reticular 
walls, with threads and striz on their top surfaces; with outline of calicle 
quite irregular (? belonging to B). 
P. Great Barrier Reef 26. On the tips of the branches the flakes stand up, 
making the calicles deep, but at the sides the walls are flat. 
P. China Sea 17. With the flaky walls nearly solid; wall granules not pro- 
nounced ; septal granules and pali on tops of flakes; all flush with the 
surface, with the fossa obscured. 
b, iii. The septal trabecule variously united into a buttress, frequently reticular, and 
gradually or suddenly thickening the wall from below upwards. 
P. Tonga Islands 2. With stout, tall, ragged wall edges, septa irregularly 
joined together, slope steeply down round deep fossa. 
P. Tonga Islands 3. With stout, smooth, low wall-edges ; septa slope gradually 
round deep fossa. 
P. Fiji Islands 7. With walls as tall, stout ridges of granules; stout septa 
slope steeply and irregularly. 
. Fiji Islands 18. Same, where calicles are large ; where small, cf. d, v. 
. Fiji Islands 20. With septal trabeculz only here and there visible, thicken- 
ing the wall; ef. also 8, v. 
P. Fiji Islands 21. The same, only with minute calicles. 
P. Ellice Islands 14. With thin, straight, frosted walls, against which the 
minute septal trabecule rise to various heights, though without showing 
any reticular formation. 
P. New Hebrides 1. With walls stout, straight, denticulate, striated longitudin- 
ally by the septal trabecule, which are joined at irregular heights by rods 
to the pali. 
P. Solomon Islands 8. See also 8, iv. 
P. Great Barrier Reef 2. A bold, open, flaky reticulum, with a thin, straggling, 
median ridge; the septal trabecule as minute granules at the tips of wall 
flakes. 
P. Great Barrier Reef 4. The septal trabecule project irregularly and roughen 
the walls, without forming any reticulum ; see also 8, v. 
P. Great Barrier Reef 13. With walls thin and perpendicular, septal trabecule 
in contact with them, and sometimes showing traces of uniting into an 
irregular inner wall (as in 3, i.). 
P. Great Barrier Reef 34. On the top with walls straight, stout, and very 
frosted, the buttresses steep and scanty; at the sides the walls appear 
broad, making the calicles shallow and funnel-shaped. 
P. Great Barrier Reef 36. With the tips of the wall trabecule as frosted 
granules ; the septal trabecule either just free of or involved in thickening 
walls, passing into @, iv. (which see). 
P. China Sea 6. This character occurs where the walls are straight rows of 
frosted granules; elsewhere passing into }, iv.
