A NEW FOSSIL SPECIES OF CARYOPHYLLIA FROM CAL- 

 IFORNIA. 



The coral described below was iu some material sent by Mr. Ralph 

 Arnold, of Leland Stanford Junior University, to the U. S. National 

 Museum to be named. Mr. W. H. Ball kindly placed the specimen in 

 my hands for determination. As it proved to be undescribed, the 

 following diagnosis has been prepared. 



CARYOPHYLLIA ARNOLDI, new species. 

 (Plate XVI, figs. 1,2.) 



Form of corallum slightly deformed inverted cone-shaped. A basal 

 scar present, but the coral in its later stages was evidently unattached. 

 Base subacute, calice nearly circular in transverse outline. 



Dimensions. — Greater diameter of calice, 16 mm.; lesser diameter of 

 calice, 15.3 mm.; height of corallum, 16.5 mm.; depth of fossa, about 

 6.5 mm. 



Costie very distinct, low, broad, rounded, or flattish, show no orna- 

 mentation, but the specimen is worn and they were probably minutely 

 granulated. There is a tendency to alternation in size, which is jDro- 

 nounced near the base. There is no observable epitheca. The wall is 

 stout, solid, a distinct pseudotheca. The costte are wide and the inter- 

 costal spaces very narrow, simply furrows, and the septa are thickened 

 at the wall. The upper margins of the septa project very slightly above
