MADEEPOEA. 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 papulosa, Eehberg, Abhand. nat. Ver. Hamburg, 1892, Bd. xii. p. 42, pi. ill. 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 striae, which under the lens appear as papillae; these are distributed over the whole 

 corallum. The species resembles M. brachiata and M, implicata, Dana, excepting that the 

 corallum is here flabellate. {Rehberg.) 



Tahiti (? Hamburg Museum). 



217. Madrepora parristella. 



Madrepora parvistella, Verrill, BuU. Mus. Comp. Zool. 1864, vol. i. p. 41 ; Stnder, Mitth. naturf. Ges. 

 Bern, 1880, p. 19. 



Corallum arborescent, numerously branched; branchlets spreading, curved, neatly 

 rounded and tapering, about 1*2 cm. diameter and 8 to 10 cm. 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. 



Singapore. 



218. Madrepora philippinensis. 



Madrepora philippinensis, Eehberg, Abhand. nat. Ver. Hamburg, 1892, Bd. xii. p. 40, pi. iii. figs. 

 13 & 13 a. 



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 ou 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.) 



* Eehberg uses the name M. microclados, Ehrb. ; but compare my account of the Berlin types.
