It is obvious that the Balanus -species here as elsewhere are 
dominant in the tidal zone, and a little below it; in 20—30 fath- 
oms the subgenus Conopea and the zlcasta-species seem to play a 
greater part in the assembly. Observations are evidently lacking in 
depths between 35 and 150 fathoms; with the last depth the Ba¬ 
lanus- and /teasta-species have disappeared, and here Scalpellum is 
the dominant genus, seconded by Megalasma and Verruca. 1 ) 
l ) Kriiger (1911) geographically characterises Verruca as „Alle Meere; 
litoral“. Hoek (1883, 1913) has nevertheless shown that almost the 
majority of Verruca -species live below 500 m, some of them even de- 
scending as far as to 3000 m or more, whereas only very few species 
are found in shallow waters.
