ANALYSIS AND DISTRIBUTION OF TYPES OF CALICLES. 275 
P. Fiji Islands 5 (spec.a). With the trabecule which form the 
ramparts, stout, nodulated, and ending as granules. The ramparts 
are round-topped. 
P. Great Barrier Reef 9. With ramparts round-topped. 
P. North Australia 4 (spec. a). Ramparts thick, smooth and round- 
topped. Trabeculz disguised, the horizontal elements arched. 
P. North Australia 4 (spec. b). Ramparts thin, low, and ragged. 
Texture of section more open than in spec. @. 
P. China Sea 9. The ramparts large, smooth and round, as a fluent 
reticulum. 
P. China Sea 10. The ramparts are very small, but the skeletal elements 
are stout. 
b. With walls of unequal width. 
i. Walls quite smooth. 
2? P. Great Barrier Reef 21. The wider wall-tops, as patches of smooth 
delicate filamentous reticulum, nowhere raised. 
ii. Walls smooth, but widening here and there; the wider walls rising into 
excrescences which run together. In the valleys the calicles may be so 
crowded as to have only single or incomplete walls like those of the more 
typical Porites. 
P. Society Islands 3. The colony rises into thin flame-like processes. 
The wide walls form a fluent reticulum. 
P. Caroline Islands 3. The colony rises into tall columns, the wide 
walls as a delicate fluent reticulum. 
P. New Guinea 1. (Said to be like P. Society Islands 3, Studer.) 
P. Sandwich Islands 4. (Apparently somewhat like P. Society Islands 3.) 
P. China Sea 12. The wider walls rise into miniature mountain ranges. 
P. Red Sea 4. Calicles scattered, visible chiefly from the fact that the 
pali are taller than the walls. Perhaps this should have been placed 
in subdivision @ ii. 
P. Red Sea 6. The wider walls rise into miniature mountain ranges. 
iii. The walls in level portions of the colony show slight upward bulgings which 
spring up wherever they widen. 
P. Solomon Islands 4. Colony rises into thin, irregular, digitiform 
processes. 
P. China Sea 3, The stock is explanate, with rounded excrescences. 
P. North Australia 3. The stock is encrusting, with sudden amorphous 
excrescences which may tower up into thin branching processes. 
iv. The walls rise into inter-calicular ramparts, which run together in patches, 
forming table-lands with depressions between. 
P. Fiji Islands 5 (spec. c). The rising walls are of regular open reticulum 
in which trabeculz are pronounced. 
P. Ellice Islands 2. The rising walls are a delicate streaming reticulum, 
the trabeculze of which are thinner than the pali (ef. P. Philippines 2).
