Three specimens of a chocolate-brown Kophohelemnon. The 

 colonies are cylindrical, 13-14 cm. high, the polyp-bearing portion 

 rather thicker (7-9 mm.) than the stalk (5-6 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. Axis thick, with a tendency to quadrangular 

 cross-section in the lower part of the colony. Spicules biscuit- 

 shaped, flat discs and oo-shapes, with a few warts. They are very 

 sparse in the cutis of the stalk, numerous in the club portion 

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



This description agrees with that of Scleroheleninon schmeltzii, 

 Kolliker. 



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

 maintain a hard and fast line between the genera Kophohelemnon 

 and Sclerohelemon, since there exist species such as Kophobdemnon 

 hixrgeri, Herklots, and K. intermedium, Thonison and Simpson, 

 partaking of the characters of both. We therefore keep this 

 species in the older genus Kophohelemnon. 



Locality. — Off Newcastle, 24-48 fathoms. 



Previously recorded from Formosa.
