Ri'iitarlx. — 'l"he little yenus AittlicntiphyU'ia has puzzled every student of the 

 classitication of corals since FourtaU-'s lirst described it." It looks at tirst sight like 

 a disc-shaped trochocyathoid coral, but the long, septal teeth immediately show that 

 it is not closely related to the Caryophylliid genera. It then recalls some of the 

 species referred to AntiUta or SyzijijophijUia. The septal margins of AntUlla are 

 dentate, hut the dentations are low, small, and rounded; vfhile those oi Sj/sygopht/ll lie 

 are large and coarse like saw teeth; furthermore, both of these genera have highly 

 developed endotheca and some exotheca. 1 do not know another genus of corals 

 that h:is the wall and interseptai loculi of the Caryophvlliida' and .septal margins 

 with long dentations. 1 am therefore proposing the family Anthemiphylliida', which 

 at present contains oidy the type genus.

 ANTHEMIPHYLLIA PACIFICA, new species. 



I'hili' VII, li'.'s. 5. 5(1. 



Corallum small. l>owl-shaped. base rounded, showing by a scar former attachment. 

 Cross-section circular. Diameter, 8. .5 mm.; height, 3.5 nun. 



There are shreds of an incomplete epitheca. The wall is externally costate, but 

 the costa^ are not large, those corresponding to the tirst and second cycles of septa 

 slightly more prominent than those corres])onding to the third and fourth. 



Septa distant, with open interseptai loculi, in four I'omplete cycles, tliose of the 

 first and second c\'cles e([ual in size and with moderat(dy exsert margins; the tertia- 

 ries are less prominent; the quaternaries the least prominent. There are distinct 

 septal groups. The primaries are free; the tertiaries fuse near the columella to the 

 secondaries; the iimer ends of the ipiaternaries appear to he free. The septal margins 

 are very spinulose, the spines tall, with rounded summits. The diameter of the 

 spines is greater parallel to the septal faces than transverse tt) them. There arc 

 granulations l)oth on the scptjil faces proper and on the spines. 



Columella somewhat sunken, not large, up[)er surface papillate. 



Calicular fossa not deep, calice shallow, or superficial.
