194 THE VOYAGE OF H.M.S. CHALLENGER. 
8. Millepora gonagra, Milne-Edwards and Haime. 
Millepora gonagra, Milne-Edwards and Haime, Cor., iii, p. 230, pl. F 3, fig. 1. 
Three specimens occur in the collection. The coenosteum in the very young stages 
takes on the peculiar, small-lobed form of the large specimens, and differs in this 
respect from the long-ridged forms of the young specimens of Millepora verrucosa ; 
nevertheless the two species are very closely allied. The pores are scattered irregularly ; 
but often the dactylopores are gathered in large numbers around the gastropores. 
Localities. —Samboangan, Philippines; Kandavu ; Tahiti.
