REPORT ON THE ALC YON ARIA. 15 



Branched spindle-shaped bodies also occur : flat spindles forked at one or both ends, 

 or giving oft* processes from the middle. Some of them may be regarded as twin forms. 

 The clubs always form the superficial layer. Irregularly distributed in the ccenenchyma, 

 they are arranged in the calyces in palisade fashion, parallel to the vertical axis. The 

 oral region is furnished with only a few small glassy spindles, which are embedded in the 

 tentacles. 



The axis is horny and flexible ; it contains a very wide axial canal and a thick 

 cortex of lamellar structure. In cross-section a vesicular appearance is produced by the 

 partial separation of the lamellae. The colour of the axis is brown, the ccenenchyma a 

 lighter shade, the calyces darker. 



Habitat.— Station 308; lat. 50° 8' 30" S., long. 74* 41' 0" W., off Tom Bay, 

 Magellan Strait; 175 fathoms; blue mud.
