Paracyathus flos Pouxr. spec. nov. 
Corallum broadly attached, short, expanding rapidly and widely, . Coste flat, 
distinct to the base, somewhat unequal, densely granulated. Septa very exsert, 
rounded or subangular with rounded corners, thickened in the middle, thus 
having a lenticular section, covered with granules, which are not arranged in 
any particular order, Four cycles, the fourth wanting in a few half-systems. 
Primary and secondary septa nearly equal, the first advancing somewhat more 
towards the centre. Pali very irregular in size, smallest in front of the prima- 
ries, largest sometimes forming two lobes in front of tertiaries. The pali sur- 
round a very deep and narrow fossa, at the bottom of which is seen the colu- 
mella formed of 5 or 6 stout papilla. The septa are horn-colored with darker 
border, the pali and columella are pure white. Height, 7 mm. ; diameter of 
stem, 3 mm.; of calicle, 10 mm. Only one specimen and fragments of another 
were obtained. 
This coral differs very much in general appearance from the typical Para- 
cyathi; at first glance it would be taken for a stunted Caryophyllia, but the 
characters, strictly taken, place it undoubtedly in the former genus.

Leptocyathus Stimpsonii Pourr. 
Fine and large specimens were obtained in 119 fathoms on the Florida bank, 
of the type first described and figured by me. In the Florida straits in 229 
fathoms quite a number were dredged of the more elongated shape, which Mr, 
Lindstróm has found to be the prevalent form in the eastern Atlantic, The 
two might perhaps be separated specifically, as in the elongated form the coste 
are flat, finely granulated, separated by very small furrows; in the spherical 
form they are sharp, with very deep furrows, covered with very small spines, 
and pass over into the septa without differentiation ; in the elongated form the 
edge of the calicle is, on the contrary, more or less sharply defined, Still, in the 
light of the great variability of some of the forms of corals, it is safer to leave 
the two forms together for the present. I now refer to this species Stephano- 
phyllia folliculus P., or Paracyathus folliculus P. 
Mr. Lindström doubts the propriety of referring these corals to the genus 
Leptocyathus, although he adopts the reference provisionally. He did not rec- 
ognize the pali, which, however, I find quite distinct in large specimens, in 
front of the tertiaries, but I have had no opportunity of direct comparison with 
the fossil species,
