198 BULLETIN OF THE 



LIST OF SPECIES, WITH REMARKS AND DESCRIPTIONS 

 OF NEW FORMS. 



MADREFORARIA. 



CARYOPHYLLIA. 



A number of specimens referable to this genus are in the collection, 

 the majority, however, in immature or imperfect condition, so that, with 

 the well-known variability in this genus, it would be a thankless labor to 

 attempt identification. The following species I still think can be retained 

 in the West-Indian fauna as well characterized : CaryopliylUa clavus, for- 

 mosa, herteriana, cornuformis, and antillarum, to which I add a new one, 

 C. polygona. C. herteriana, so abundant at Barbadoes, is not represented 

 h\ the present collection by any undoubted specimens. C. antillarum is 

 rare. Of C. formosa there are two fine specimens from 95 fathoms on 

 the edge of the Yucatan bank, and a number of young specimens from 

 various localities can probably be referred to this species. C. cornu- 

 formis is represented by several dead and worn specimens and two fresh 

 ones from 310 fathoms, off Bahia Honda, Cuba ; they are mostly larger 

 than those described in my " Deep-Sea Corals." I must correct here 

 my former description, which mentioned four cycles, with the pali in 

 front of the secondary. There are only three, and thus there is no 

 •anomaly in the arrangement of the pali, which are in front of the penul- 

 timate cycle. The figure on Plate I. was correct, and I cannot account 

 now for my mistake in the text. In a very old specimen there appear 

 to be some additional septa, probably of the fourth order, but the speci- 

 men is too much worn for study. C. Pourtalesi Duncan is probably 

 identical with tliis species. 



Caryophyllia polygona Podrt. spec. nov. 



Corallum fixed by a stout peduncle, rather massive. Primary and secondary 

 costaD very prominent, subcristiform, and extending down to the peduncle, 

 those of the younger cycles very faint in the younger specinien, entirely 

 obsolete in the older, whicli has also lost most of tlie gnuuilation visible in the 

 fonner on the peduncle and near the border. Culicle ol)h)ng, wall thick ; septa 

 thick, Bniooth or very faintly granulated. Four complete cycles and six sys- 

 tems ; in the larger specimen the fifth cycle is fully developed in one of the 

 half-systems. Priniar}' and secondary septa nearly equal, exsert ; twelve pali 

 fronting tlie tertiaries. Columella formed by seven or eight twistel laniellaj in
