11. Lemnaliadm. Coral simple at the base ; stem formed of the clustered 
cylindrical, tubular bodies of the polypes ; outer surface smooth, without spi- 
cules. Genera : 1. Lemnaliay Gray (Verrill objects to his Ammothea nitida 
being included in this genus, for its surface is filled with an abundance of mi- 
nute, slender, interlaced spicules) j 2. Verrillianay gen. nov.. Gray, /. c. p. 130, 
for Alcyonium ramosuniy Q. & G. (Verrill says that Gray includes his Nephthya 
thyrsotdea as a synonym of Ammothea thyrsoidesj Ehrb. ; but the latter is de- 
stitute of external spicules, while the former is described and figured with 
long external spicules ; for this species Verrill makes the new genus Eu- 
nephthya), 
12. Paralcyonida. Coral membranaceous, branched above, smooth, with 
minute dermal spicules near the mouths of the polypes ; the bodies of the 
polypes opening into each other, making a common cavity. The coral re- 
tractile into a tubular sheath covered with large dermal spicules. Tentacles 
retractile. Genus Paralcyoniumj M.-Edw. 
Eunephthyay gen. nov., Verrill, /. c. p. 284, for Nepthya thyrsoideay Verrill ; 
E, glomerata, sp. n., Verrill (Liitken, sp.), 1. c. p. 284, from Greenland. 
Alcyonium (P) hradleyiy sp. n., Verrill, 1. c. p. 459, Panama. 
Tubtpora musica. The llecorder describes and figures tho animal of this 
species met with at tho Seychelles. The tube is constructed of fusiform cal- 
careous spicules, which become consolidated. Spicules of various forms are 
also met with in the ectodermic layer of the polype.
