Linens corrugatus. The cephalic slits are wider and larger altogether (Fig. 30), and this, 

 with the absence of " eyes " and presence of a caudal appendage characterize the species.

The specimens were taken at the following WS stations: 73 (N 52), 228 (N 100), 239 

 (N 72), 246 (N 97), 249 (N 65). 



Order HOPLONEMERTEA 

 Genus Amphiporus, Ehrenberg 

 Amphiporus falklandicus, n.sp. (Fig. 36 D). 



This species is represented by a number of specimens. It is closely related anatomi- 

 cally to A. gerlachei, Burger and A. lecointei, Burger. I have separated them on the 

 following grounds: the colour in life from a single colour note; the size and shape of 

 the preserved specimens and the position of the junction of the oesophagus and stomach 

 with relation to the brain. 



The station numbers and details of gear and depth, with the length, breadth and serial 

 numbers of the specimens are given in the table below :
