higher cycles. The outer ends of the septa are thick, l)ecoinin<r thinner toward the 

 center, the first C3'cle of septa slightl}' longer than the third, and the third slightly 

 longer than the second. The septal faces exhibit undulations coinciding with the 

 courses of the septal triibecuhv and have granulations along their crests. The 

 granulations are numerous, crowded, and prominent. 



There are eight rather large, stout, undulated, and granulated pali, standing 

 before the septa of the tliird cycle. 



The columella (X)nsists of several, three to five, more or less twisted laths. 



Calice shallow. 



Localities. —South coast of Molokai Island: Station 3Si}7, depth 319 to 371 

 fathoms; bottom, light graj^-brown nuid; temperature of bottom, 42. 1-" F. (two 

 specimens, one attached to the other). Station 3828, depth 281 to 319 fathoms; bot- 

 tom, broken-shell, gi-avel; temperature of bottom, 4-3.8'-' F. (one specimen, the type).

Remarks. — This species is based on three specimens. The type has been broken 

 from its attachment, but has the basal expansion preserved, one of the other speci- 

 mens is attached to the third. The character of these specimens is very constant, 

 but shows variation in the number and size of the columellar laths. They are very 

 closely related to C<iri/<>pliyl1!a ei>rni{f<>rmi!<Vo\xvii\\l'^. from the West Indies, of which 

 there is in the United States National Museum one spei'imen with seven well-developed 

 and one rudimentary palus. In size and general appearance the two species are scarcely 

 distinguishable. A ditierence, probably of no great value, is that C. octojxili has a 

 more expanded base than C. eornuformis. There seems to be good ditierences in the 

 septal characters: In C. octopali the last cycle of septa are persistently as long as, or 

 longer than those of the preceding cycle, and the inner ends of the second cycle are 

 not thickened. In V. eoniiiforiiiis the last cycle of septa are persistently shorter 

 than those of the preceding cycle; the inner ends of the septa, before which the pall 

 stand, are thickened, the septa are not so crowded, the margins of the fii-st and second 

 cycles are more exsert, and the septal faces are not so densely granulated.

riat(> V, tis;s. :!, 3<). 



This variety is separated from the typical ncfapali by the exsert septa of the first 

 cycle, which projects fully 1 nun. bej'ond the upper edge of the corallum wall. The 

 pali are six or seven in number, not eight, as in typical octopali. The septal lengths 

 are as in oefoixili. 



This variety is represented by a cluster of individuals growing attached to one 

 anothei' by their bases.
