in the Dotonidse ; Bergh, however, adding: "Bei der Formulirung 

 der Charaktere der Dotoniden ist auf die Hancockien oder Govien 

 keine Riicksicht genommen, weil die Stellung dieser merkwiirdigen, 

 gleichsam mehrere Familien verbindenden Gattung, bei der bisherigen 

 nur vorlaufigen Untersuchung Trinchese's noch ganz unsicher ist." I 

 will only allude here to one view implied rather than expressed by 

 Mr. Garstang.* He compared a lobe of the pleuropodium of Hancockia 

 with one of the four arcuate lobes of the "raised curtain" forming 

 the pleuropodium in Lomanotus. The side view which I give of the 

 latter genns shows that the lobes are distinct and that the breaks 

 occur between the segments having the large dorsal papillae as their 

 centres (PI. VII. fig. 2).
