bearing internode. Thev are thus closely approximated. The yiematojihores have a 

 widely expanded, trumpet-shaped mouth, and besides those already mentioned, there 

 are three on each hydrotheca-bearing internode, one median and proximal, standing 

 on a slight angle of the internodal perisarc, two lateral, each borne on a process which 

 rests against the side of the hydrotheca. Only one nematophore occurs on each 

 intermediate internode. 



Gonosome. — Not observed. 



Locality, etc. — Dredged at the entrance of Saldanha Bay, Cape Colony, in 25 fathoms. 

 Date, 21st May 1904. 



The general architecture approaches that of Antennopsis fascicularis (Allman, 

 1883, p. 24), but there are differences in the proximity of the hydrothecse and in the 

 number and distribution of the nematophores. 



We have named this species after the Scotia — the ship of the Scottish National 

 Antarctic Expedition.
