82 AOARICIA. 



MYCEDIUM Oken. 

 Mycedium fragile Dana. 



(See Deep-Sea Corals, page 48.) I do not know the upper limit in 

 depth of this species, having never seen it in shoal water. It is repre- 

 sented in the Museum by numerous fine specimens collected by differ- 

 ent persons who did not use a dredge, so that it must probably reach 

 to two or three fathoms from the surface. 



Agaricia vnJata is mentioned by Dana as being found at Key West. 

 There is no specimen in the Museum. It is found near Havana. ( Coll. 

 Araiiffo.) 



AGARICIA Lamk. 

 Agaricia agaricites M.-Edw. & H. 



Mdilrrporn ar/iiriciles Pai.i.as. 



Mwlrepora <i</(iriciles Ellis & Sol. PI. G3 (indifferent figure). 



Piwonia (igfiricile.t Lamk. 



Mijcediti a/jaricilcs Daxa. 



Quite common on the reef, forming occasionally lai'ge clusters on the 

 sides of masses of other corals. 



Agaricia purpurea Li.sieii;. 



jMyi-c-did piirpurca Dana. 



(hi the authority of Professor Yerrill, I include this species among 

 the Florida corals. The Museum of Comparative Zoology has no un- 

 dou])ted specimens of it from that coast, but has some from Hayti, of 

 large size. Young specimens would probably be difficidt to distinguish 

 fi'om young .1. aijaricifes, which is at first uuifacial.
