@ The Crab Ledge Bryozoa have not been listed by stations. 
In a similar way we have represented the wealth in species of each of the types of 
bottom which have been distinguished (see p. 70). 
IV. Average number of genera and species per dredge haul for the three types of bottom.

to be noted that the number of species is greatest for the stony bottoms and least for the 
sandy ones.
