I collected at station 3446, in the La Cruz marl, first deep cutting 

 east of La Cruz, near Santiago, Cuba, casts of the surface of a species 

 of SiylopJiora. Squeezes of the surfaces of these casts agree com- 

 pletely with specimens from Santo Domingo identified by me as 

 S. affinis. I am therefore attaching that name to the specimens. 

 It is probable that similar casts from other localities in Cuba repre- 

 sent the same species. 



STYLOPHORA PORTOBELLENSIS, new species. 



Plate 76, figs. 1, la. 



Corallum ramose, branches compressed, more or less contorted 

 fiabellate at the terminals. Growth form, therefore, similar to that 

 of StylopJbora imperatoris. The type is 37.5 mm. long; smaller 

 diameter of basal end 10 mm., width of base about 13 mm.; maximum 

 width of branch in horizontal plane about 22 mm., thickness at same 

 level 10 mm. 



Calices shallow, diameter averages about 0.75 mm. or slightly 

 less; distance apart approximately equals the calicular diameter, 

 in places less, 0.25 to 0.5 mm.; margins flush with the coenenchymal 

 surface, in places slightly elevated on the upper side, but not enough 

 to form a distinct upper lip. 



Septa, six primaries distinct, rather thin, extend to the columella; 

 no vestige of secondaries was observed. 



Columella, a pointed style, moderately prominent, thickened below 

 the bottom of the calice. 



Coenenchyma dense or costulate with an intercalicular ridge and 

 cells on its sides. The surface is worn, but vestiges of small granu- 

 lations may be recognized. Axis of the corallum spongy. 



Locality ami geologic occurrence. — Panama, probably from near 

 Porto Bello, collected by D, St. Clair; geologic horizon unknown. 



Type.— No. 324762, U.S.N.M. 



This coral has considerable resemblance to Stytopliora goethalsi, but 

 its calices are distinctly larger, and their upper margins are in some 

 places slightly raised. StylopJiora imperatoris has larger calices with 

 distinct upper hps. StylopJiora portohellensis appears most closely 

 related to Stylo phora ajfmis Duncan, from the Nivaje shale of Santo 

 Domingo. 



STYLOPHORA GpETHALSI, new species. 



Plate 75, figs. 2, 3, 4. 



Corallum ramose, with branches subelliptical or much compressed 

 in cross-section, in this character resembling S. imperatoris. Branch 

 summits frequently or usually with digitiform protuberances (see 

 pi. 75, fig. 2). ■' 



Calices shallow, decidedly small, 0.5 to 0.75 mm. in diameter; and 

 relatively distant, from a calicular diameter up to 1.5 mm. apart.
