2. Stylophoba tlabellata Quelch. 



Stylophora flabellata, Quelch, ' Challenge!'' Eeport on Eeet'-Corals, 

 p. 54, pi. ii. figs. 1-1 b (1886). 



I have referred to this species two small fragments which 

 correspond very closely to the ' Challenger ' specimen in the British 

 Museum. 



Funafuti ; lagoon, 8 fathoms. 



3. Stylophoba digitata Pallas. 



Madrepora digitata, Pallas, Elench. Zooph. p. 326 (1766). 



Stylojphora digitata, Klunzinger, Die Korallthiere des Eothen 

 Meeres, Th. ii. p. 61, pi. vii. fig. 5 and pi. viii. fig. 1. 



I have referred to this species a clump, 10 cm. high by 14 cm. 

 broad, which corresponds fairly well to Klunziuger's description. 

 The ccenenchyma is covered with long pointed spines which on the 

 sides of the branches project, especially on the theca over the calice, 

 forming a moderately acute prominence or hp. At the ends of the 

 lower branches the theca projects equally around each calice, but 

 the terminal calices of the longer branches are more or less poly- 

 gonal and separated only by a thin wall, the fused theca, without 

 any ccenenchyma. The specimen was living at the extreme edge 

 of the reef, and it is probable that the longer branches had reached 

 the low-tide level and were unable to grow further. Some, too, show 

 a slight tendency to broaden out at their ends. 



There are in the terminal calices of the branches six distinct, 

 smooth, thin septa, which fuse below with the small, styliform but 

 prominent columella. In the side calices of the branches the 

 primary septa are always distinct and similar, but the columella 

 can seldom be seen. 



Funafuti ; outer reef. 



4. Stylophora septata, n. sp. (Plate LXII. fig. 1.) 



The specimen is a colony, about 9 cm. in diameter by 6 cm. high, 

 of the general form of /S'. digitata, consisting of a number of 

 branches arising from a common base. The branches are some- 

 what fused below but free above, ending usually in two or three 

 small lobes 8-14 mm. in breadth by 4-6 mm. thick. 



The terminal calices of the branches are very crowded together, 

 and there is between them no development of ccenenchyma, which 

 is, however, well formed between the side calices. The latter are 

 about -9 mm. in diameter and there are generally 4 in 5 mm. 

 The upper wall of these calices projects usually for about 1 mm. 

 into an obtuse lip, which is on the outside, as also is the ccenen- 

 chyma between, coveued with short, rough, granular spines, which 

 are often much compressed and arranged in striae. 



The calices of the ends of the branches are very deep, \A-ith the 

 six primaiy septa well developed and with rough edges ; they are 

 prolonged deep down in the cell to meet a very delicate style-like 

 projecting columella. The secondary septa between are distinct,
