The above list shows that the collection contains 102 species of 

 Alcyonaria distributed among 54 genera belonging to 18 families. 

 There are 40 new species and 2 new genera. The Muriceidse includes 

 the largest number of genera (11) and 17 species. The family con- 

 taining the greatest number of species is the Prinmoidae, with 18 

 species and 1 new genus. 



The genus represented by the largest number of species is Pen- 

 natula, with 9 species, 4 of which are new, and this genus probably 

 has the greatest geographical range. 



The 40 new species, constituting just about 39 per cent of the 

 whole number, are pretty well distributed over the various families 

 and genera of the order, although there is a proportionally greater 

 number in the family Muriceidae than in any other, 11 of the 17 

 species of this family being new. Of the 18 species of the Prinmoidae 

 but 5 are new.
