Lafcea pocillum Hincks^ Br. Hyd. Zooph., 1868, p. 204. 



Distribution. — St. Andrews. 



There was no gonosome present on the St. Andrews specimens to settle the ques- 

 tion definitely as to whether this species is a Lafcea or an Hebella but as there is a 

 distinct diaphragm in the hydrotheca, it agrees with Hebella in that respect and is so 

 placed.
