198 BULLETIN OF THE 
LIST OF SPECIES, WITH REMARKS AND DESCRIPTIONS 
OF NEW FORMS. 
MADREPORARIA. 
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 : Caryophyllia clavus, for- 
mosa, berteriana, cornuformis, and antillarum, to which I add a new one, 
C. polygona. C. berteriana, so abundant at Barbadoes, is not represented 
in 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. O. 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 thero is no 
anomaly in the arrangement of the pali, which are in front of tho 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. O, Pourtalesi Duncan is probably 
identical with this species. 
Caryophyllia polygona Pourt. spec. nov. 
Corallum fixed by a stout peduncle, rather massive, Primary and secondary 
costa very prominent, subcristiform, and extending down to the peduncle, 
those of the younger cycles very faint in the younger specimen, entirely 
obsolete in the older, which has also lost most of the granulation visible in the 
former on the peduncle and near the border, Calicle oblong, wall thick ; septa 
thick, smooth 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. Primary and secondary septa nearly equal, exsert ; twelve pali 
fronting the tertiaries. Columella formed by seven or eight twisted lamella in
