 biscrial alternate colourless polyps (7 mm. in length by 

 2 mm. in breadth, Avith eight projecting acieular points),

 Locality. 'Station 169, 91 fath. 



Family Umbelliilidae. 



The collection includes representatives of five or six species 

 of Umbellula which have not been adequately studied as yet. 



Family AnthoptilidaB. 

 Anthoptilum Murrayi, Kolliker. 



Two incomplete specimens with the polyps all rubbed off. 

 The pit-like markings left show that the autozooids were 

 arranged in oblique transverse rows of two or three. The 

 prorachidial surface is marked by a deep broad groove, the 

 metaraehidial surface by a narrow groove, so that the polyp- 

 bearing surface is divided into two strips. 



The specimens differ from A. Murrayi in being altogether 

 dull white, while the ' Challenger ' specimen was pale red, 

 with brown polyps and colourless stalk. Moreover, the axis 

 in the present specimens is more or less quadrangular, not 

 cylindrical. 



Locality. Station 10^, 1000 fath.

 side, with a basal club-shaped swelling, with dark-coloured 

 autozooids with spicular calices in groups of four, with 

 minute Avhite prorachidial siphonozooids. The spicules are 

 long smooth rods with ribs.
