570 ZOOLOGY OF FERNANDO NORONHA. 



neiglibouring ealices, iustead of some vestige of iuterspace and 

 eostfe. 



Verrill aud Pourtalcs noticed the alliance of the species with 

 the genera Gom'asfrcea and Mceandrina. In a small specimen 

 the Goniastroid appearance is striking, and the costie between 

 the calices are only visible at one spot. There are several rolled 

 specimens, and, as Pourtales remarked, they resemble Goni- 

 astroids very much. 



Fayia ANANAS, Lamcirck, sp. 



The specimens have the usual well-developed columella, the 

 costse are very visible in one, and the fourth cycle of septa is 

 incomplete.

A somewhat worn aud 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 can 

 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 Eat Island. They were 

 washed up on the south-east corner with a number of Sponges.

 SiDERASTRiEA SIDEREA, ElUs 4' Solalld., 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, Verrill, from the 

 Abrolhos Eeef . 



Remarks. 



This little Coral fauna has the Abrolhos Keef homotaxis, and 

 the species are fairly intermediate between those of the same 

 genera of that reef and of the Caribbean Sea.
