There is no douht that the figure in Van Heurck, Synopsis PI. 82, 

 f. 3 represents the species which has been named longlcniris by Gleve, 

 and consequently the older name auglicus must have the priority.

Professor Gleve to whom 1 

 sent my figure (fig. 10) thinks that 

 the form belongs to the C. breve 

 Schi^itt, and I can agree with him. 

 It resembles striking small forms 

 of C. Lorenzianum but is easily 

 recognisable by the single chro- 

 matophore antl the smooth awns.

Area: Along the coasts of 

 Europe from Westmannao at Island
