Four monosiphonic, unbranched, simple pinnate colonies, 
the largest 86 mm. in height, were found associated with 
Aglaophenia divaricata. The measurements of the tropho- 
some agree very closely with those of Victorian specimens 
and with calculations made from Bale’s figures. In one 
case the terminal aperture of the mesial sarcotheca is 
wanting, the nematophore being closed at the end. Such 
an arrangement, however, appears to be temporary or 
abnormal.
