ZOOLOGY OF FERNANDO NORONHA. 
neighbouring calices, instead of some vestige of interspace and 
costse. 
Terrill and Pourtales noticed the alliance of the species with 
the genera Goniastrcea and Mcecmdrina. In a small specimen 
the Goniastroid appearance is striking, and the costa?, between 
the calices are only visible at one spot. There are several rolled 
specimens, and, as Pourtales remarked, they resemble Goni- 
astroids very much. 
Favia ananas, Lamarck , sp. 
The specimens have the usual well-developed columella, the 
costae are very visible in one, and the fourth cycle of septa is 
incomplete.

A somewhat worn and broken coral, very Coelorian in appear- 
ance, and with large calices, some long and serial in appearance, 
but really the result of fissiparity, appears to be a specimen of 
this form, the habitat of which has hitherto been unknown. The 
walls are close, but in many places their former separation cau 
be shown. It is a very erratic species, and better specimens are 
required. 
A very worn specimen of the same species was also obtained. 
These two specimens came from Fat Island. They were 
washed up on the south-east corner with a number of Sponges.

SlDERASTRiEA SIDEREA, Ellis Soland., Sp. 
This specimen, and indeed all the rolled ones besides, have smaller 
calices than the Caribbean type, but that is the only distinction. 
They greatly resemble Siderastrcea stellata, Terrill, from the 
Abrolhos Feef. 
Remarks. 
This little Coral fauna has the Abrolhos Eeef homotaxis, and 
the species are fairly intermediate between those of the same 
genera of that reef and of the Caribbean Sea.
