REPORT ON THE REEF-CORALS. 193 
Professor Moseley remarks that Millepora ramosa seems to thrive best in the 
shade." 
Locality.— Bermuda. 
5. Millepora intricata, Milne-Edwards and Haime. 
Millepora intricata, Milne-Edwards and Haime, Cor., iii. p. 229, pl. F 2, fig. 2. 
A single small specimen oceurs in the collection. The pores in this species are 
arranged in more or less regular cyclosystems, though numerous dactylopores are 
scattered throughout the surface of the coenosteum. The pores are very small, and 
the dactylopores especially are very minute. 
Locality.—Amboina. 
6. Millepora confertissima, n. sp. (Pl. VU. figs. 44a). 
Ccenosteum consisting of an extremely dense, flat-topped, almost square clump of 
closely interlaced branches and branchlets, which are intimately coalescent, and so closely 
placed as to leave only very small and narrow openings between them. Branches com- 
pressed and very small, about 4 mm. thick, but generally much wider, very closely and 
shortly ramose, and often forming fronds by lateral coalescence of its branchlets. 
Branchlets very small, short, and compressed, from about 5 to 7 mm. long, often less, 
about 4 mm. wide and 2 mm. thick, subpalmate, bearing a few obtuse, smaller branchlets. 
Surface very smooth and even. Pores unequal, and not distinctly gathered into 
cyclosystems ; gastropores very small, rather wide apart; dactylopores very minute and 
numerous. Ampull absent. 
The peculiarly packed and intimate branching of this species gives it a striking habit, 
which will easily distinguish it. 
Locality.—Ternate. 
7. Millepora nodosa, Esper. 
Millepora aleicornis, var. nodosa, Esper, Pflanz., i. p. 199, Millep. pl. ix. 
Millepora nodosa, Moseley, Zool. Chall. Exp., part vil. p. 13. 
Several fragments and small specimens were obtained. Special interest attaches 
to this form, since it was on specimens of this species of the genus that the classical 
researches of Professor Moseley were based. 
Locality.—Tahiti.
