MADREPORA. 197 
The type specimen could not be found when I visited the Paris Museum, and there is 
no present means of identifying the species with certainty. 
The specimen in the British Museum referred by Briiggemann to this species does not 
agree with the above description and constitutes the type of M. botryodes, mihi. 
Habitat not recorded. 
216. Madrepora papillosa. 
Madrepora papillosa, Rehberg, Abhand. nat. Ver. Hamburg, 1892, Bd. xii. p. 42, pl. iii. figs. 12 & 14, 
The colony grows on a mother-of-pearl shell and has a broad pedicel, which widens out 
into a fan-shaped and laxly branched corallum. The twigs all extend in one plane, somewhat 
slender and bent, and form together a circular flabellum 30 cm. high. The corallites are 
slender (appressed tubular) and give a dentate outline to the branches, The axial corallites 
differ little from the radial ones. Corallite-wall longitudinally striate, with dense thornlets on 
the striz, which under the lens appear as papill; these are distributed over the whole 
corallum. The species resembles M. brachiata and M. implicata, Dana, excepting that the 
corallum is here flabellate. (Rehberg.)

217. Madrepora parvistella, 
Madrepora parvistella, Verrill, Bull. Mus. Comp. Zool. 1864, vol. i. p. 41; Studer, Mitth. naturf. Ges. 
Bern, 1880, p. 19. 
Corallum arborescent, numerously branched; branchlets spreading, curved, neatly 
rounded and tapering, about 1:2 em. diameter and 8 to 10 em. long. Corallites evenly 
crowded, very small, short, tubular, opening obliquely upward; exterior costate, scabrous ; 
cells small, broad oval, stellate ; 12 septa distinct, the two largest nearly meet in the centre.

218. Madrepora philippinensis. 
Madrepora philippinensis, Rehberg, Abhand. nat. Ver. Hamburg, 1892, Bd. xii. p. 40, pl. iii. figs. 
13 & 134. 
Corallum similar to that of M. spicifera, Dana*, but with small branched twigs instead 
of simple ones, and the under surface is provided with spreading corallites ; the branches 
also bear many immersed corallites, and the whole corallum differs in structure and presents 
an appearance like pumice-stone, ending on the corallite-wall as narrow striations. The 
corallites are mostly hemicotyloid (« schwalbennestartig ”), but those near the apex of a twig 
are more elongate, straight or bent. ( Rehberg.) 
* Rehberg uses the name WM. macroclados, Ehrb.; but compare my account of the Berlin types.
