Geologic occurrence. JacksOniaU StagC. 



Type. — United States National Museum. 



The very large but acute costal easily characterize this species. 

 They are sometimes fully 1 mm. in height. 



Caryophyllia should have septa with entire margins, Ijut there is evi- 

 dently SO great a variation within this specimen itself in the character of the 

 septal margins, that it does not seem ijossible to refer it to another genus, 

 when, excepting this peculiarity, every other feature is typical for that 



genus. 



Caryophyllia texana sp. nov. 



PI. IX, figs. 3 and 4. 



Corallum attached, a short pedicel and scar of attachment usually 

 present; form short cornute, curved in plane of the shorter axis of the 

 calice; transverse outline elliptical. Costaj corresponding to all cycles of 

 septa; not prominent, regulaidy alternating in size; rather acute, surface 

 granulate. The presence of epitheca doubtful. Septa project but little 

 above the upper margin of the corallum wall, in at least four cycles, rather 

 stout, sides granulate. Margins entire. Septa composed of completely 

 fused ascending trabeculse, with line of divergence at the wall. Pali present, 

 stout, well developed. Details difficult to discover, because of the poor state 

 of preservation of the interior of the specimens. Apparently in one crown 

 before the tertiaiy septa. (It is because of this arrangement of pali that 

 the species is referred to Caryophyllia.) Details of the columella can not 

 be made out from the material in hand.
