112 BULLETIN OF THE 



Bathyactis symmetrica Mos. 



Fungia sijmmetrica Pourt. 



The tentacles are rather small, and are arranged, as in the true Fungise, at 

 variable distances from the mouth, according to the order of the septa, but as 

 in the latter are very symmetrical ; the tentacles are also at regular distances, 

 according to the cycle. 



Range from 116 to 400 fathoms, in thirteen stations, off Havana, Santa Cruz, 

 Montserrat, Guadeloupe, Martinique, St. Lucia, Grenadines, Grenada, and 

 Barbados. 



Guynia annulata Dunc. 



Range from 150 to 357 fathoms, in three stations, off Saba Bank, Montserrat, 

 and Martinitj[ue. 



Duneania barbadensis Pourt. 



I group this and the following species together provisionally, but not under 

 the name of Rugosa, a group which requires revision, and among the characters 

 of which a tetrameral arrangement of the septa cannot be maintained. It is 

 rather singular that no other specimen of Haplophyllia has been obtained in 

 all the dredgings taken in West-Indian waters. It is much to be regretted, as 

 the typical specimen was somewhat deformed. 



Range from 103 fathoms, off Barbados, to 191 fathoms, off Martinique. 



Anthemiphyllia patera Pourt. 



Plate II. Fiss. 5 and 6. 



The description in my former paper was based on a single specimen. A 

 number of fine ones obtained this year in the same locality renders it necessary 

 to modify it in several points. 



The outer surface is covered with a smooth porcellaneous epitheca, without 

 distinct border, concealing the costsc nearly up to the border of the calicle, 

 where they become somewhat prominent, and beset with short spines. There 

 is a coarse spongy columella, with flat fasciculate or oftener foliaceous surface. 

 The interseptal chambers are open down to the bottom, but constricted very 

 much at intervals by a series of stout half floors or shelves projecting from the 

 columella outward. The wall is thick. The transversely flattened spines of 

 the septa are similar to those of Diaseris crispa; similar ones are seen also in 

 well-preserved specimens of Montlivaultia bormidensis. 



I am still in doubt about its affinities ; in general appearance it resembles an 

 Antillia, but the absence of a complete endotheca is against placing it in that 

 proximity. It may possibly be related to Discotrochus. 



From 250 to 400 fathoms, off Havana.
