apart. The small pores are very minute, numerous, scattered between 

 the larger ones, and often showing a tendency to arrange thcmscleves 

 around them in circles of six or eight. The tissue is, for the genus, 

 very firm and compact. 



Abrolhos Reefs,— C. F. Hartt. 



The form of the branches, distinctness in outline of the cells, and 

 smoothness and firmness of texture, distinguish this species very 

 clearly from any of the numerous varieties of M. alcicornis, and 

 other West Indian species. 



Quite common on the border of the reef at the " Lixo," Abrolhos, below low-tide, 

 also on the coral reef of Porto Seguro, in 3-4 feet water, low-tide. Color, when alive, 

 light pinkish. — c. f. h. 



Millepora Braziliensis Verriii, sp. nov. 



Corallum forming large, irregularly lobed and branched masses, the 

 branches erect, angular or flattened, or forming broad, convoluted 

 and folded, rough plates, with acute edges and summits, the sides 

 covered with sharp, irregular, angular, crest-shaped and conical 

 prominences, varying much in size and elevation, often becoming 

 continuous ridges, usually standing at right-angles to the sides of the 

 branches ; cells small, circular, distantly scattered ; texture firm and 

 compact ; height about one foot ; breadth one foot and a half ; 

 branches and plates '5 to -8 of an inch thick, sometimes 6 inches 

 wide. 



Pernambuco, Brazil, — C. F. Hartt. 



In texture and the character of the cells, this resembles the preced- 

 ing species, and possibly it may eventually prove to be only a vaiiety 

 of it. It differs, however, very remarkably in the mode of growth 

 and form of the branches. On the edges and sides of the branches 

 there are often pits of various sizes up to an inch in diameter and 

 depth. 



Small specimens occur also on the reefs at the Island of Sta. Barbara dos AbroUioa, 

 Color, when alive, pinkish. — c f. h. 



Millepora alcicornis Linn., var. cellulosa Verrill. 



Corallum consisting of numerous, irregular, rather short branches 

 arising from a thick base. Branchlets proliferous, or digitate at the 

 ends, the last divisions short, mostly compressed, and acute at the 

 tips. Some of the branches occasionally coalesce, so as to leave small 

 openings. Cells numerous, crowded, rather large for the genus, each 

 sunken in a distinct depression, the wall rising up into an acute ridge 

 between them. Texture rather open and coarsely porous. 



Pernambuco, Brazil, — C. F. Hartt.
