From the above it is evident that our specimen, although possessing certain 

 of the essential characters of the two genera described, differs somewhat from 

 both and could not be included in either. We do not feel inclined, however, to 

 establish a new genus, inasmuch as the distinguishing features do not appear to 

 us to be generic. We would rather suggest the abolition of Srkrohdemnon, 

 retaining the species of both genera under the older genus KnphohelemHon, with 

 A', hargeri, Herklots, and K. intermedimn, n. sp., as connecting forms. 



EMENDED DIAGNOSIS OF KOPHOBELEMNON. 

 Colony club-shaped or cylindrical with a narrow longitudinal zone on the 

 ventral side free from autozooids ; autozooids arranged in one or more longitu- 

 dinal rows on each side ; spicules in the body polyp and tentacles, in the lower 

 half of the polyp only or in neither ; siphonozooids numerous, in the spaces 

 between the autozooids and surrounded by spicules ; axis quadrangular or 

 sub-cylindrical ; spicules : angled needles, smooth rods, short plates, spindles 

 and biscuit-shaped bodies in the cutis and rachis but absent from the interior.

^ KopJiobelemnon hurgeri, Herklots, approaches Sclerobelemnon in many respects, e.g., in (1) 

 shape of spicules, (2) the small number of spicules in the polyps, and (3) the shape and nature 

 of the axis.
