X, D, 2 Light: Philippine Alcyonaria 167 



by Ashworth/^ and in Zanzibar by Thomson and Henderson ^' 

 and Crossland and May, it was to be expected that such a fauna 

 would be found in the Philippines, where conditions are much 

 the same as in these regions. 



It is interesting, in conclusion, to note the striking similarity 

 between the general littoral alcyonarian fauna of the Philippines 

 and a region so distant as Zanzibar. Briefly stated, the most 

 striking similarities are: The presence of Tiibipora "wherever 

 coral grows," the large number of species of Lemnalia,*' the 

 presence of Paralemnalia thrysoides (Ehrbg.) Kiikenthal *^ and 

 of a few common species of Nephthya and Lithophytum, the 

 presence in considerable quantities of Telesto and Coelogorgia, 

 the abundance of Xeniidse and Cornulariidae, and the "great 

 masses of Sclerophytum."

" A number of species now known to belong to the genus Lemnalia were 

 at that time placed in the genus Lithophytum. 



*' This species, formerly placed in the genus Lithophytum, has been taken 

 by Kiikenthal as the type species of his new genus Paralemnalia. See
