Three specimens of a chocolate-brown Kophobdemnon. The 

 colonies are cylindrical, 13-1 4 cm. high, the polyp-bearing portion 

 rather thicker (7-9 mm.) than the stalk (5-G mm.) ; there is no 

 terminal bladder ; the polyps are arranged in rather irregular 

 longitudinal rows, leaving only a small bare strip on the pro- 

 rachidial side. The tentacles of the polyps are without spicules. 

 The upper part of the polyps is much poorer in spicules than the 

 lower. Siphonozooids, small, brown, wart-like, in very numerous 

 longitudinal rows. A.\is thick, with a tendency to ([uadransiular 

 cross-section in the lower ])art of the colony. Spicules biscuit- 

 shaped, flat discs and oi-shapes, with a few waits. Thej- are very 

 sparse in the cuti.s of the stalk, numerous in the club portion 

 lound the siphonozooids and on the polyps, absent in the interior. 



This descri|>tion agrees with that of Sclerohcleianon schmellzii, 

 Kolliker. 



Thomson and Simpson have shown' ' that it is impossible to 

 maintain a hard and fast line between the genern Kophobelemnon 

 and ScUrobelemon, since there e.xist species sucli as Ko/)/iobelemiion 

 biirgeri, Herklots, and K. intermedium, Thom.son and Simpson, 

 partaking of the characters of both. We therefore keep this 

 species in the older genus Kopliobelemnoti. 



Locality. — Off Newcastle, 24-48 fathoms.
