Echinogorgia anrantiaca Verrill, Notes on Radiata, 1867 — 71, p- 557- 



Stat. 60. Haingsisi, Samau Island, Timor. 23 meters. Coral bottom. 



Stat. 164. i°42'.5 S., I30°47'.5 E. near New Guinea. 32 meters. Sand and stones. 



Stat. 204. 4°2o'S., 1 22° 58' E., near Baton Island. 75 — 94 meters. Sand. 



Colony (incomplete) a slender stem 30 cm. long-, with a single simple branch arising 

 7.3 mm. from its base and attaining a length of 8.5 cm. Diameter of stem 2.4 mm. The calyces 

 are closely but unevenly distributed on all sides of the stem and branch. They are often 

 contiguous, but sometimes as much as 1.7 mm. apart. 



The individual calyces are low rounded verruccc, a typical one measuring i.i mm. in 

 height and 1.5 mm. in diameter at the base. The calyx walls are covered with projections 

 which are flattened, smooth and imbricating. They are the exposed portions of spicules which 

 have a foliaceous, expanded base embedded in the coenenchyma of the walls. Some of these 

 glassy projections reach slightly above the calyx margin, but they are not conspicuous. The 

 polyps are retractile, the calyx walls being capable of enclosing and covering them completely. 

 The collaret and operculum are extremely delicate, both being formed of very slender spindles 

 arranged in the usual way. 



Spicules. The Echinogorgia type of spicule is prominent, consisting of a multiradiate 

 base which is distinctly tuberculate and from which arise one or several clear, smooth, flattened 

 or foliaceous expansions. Often there is but one such expansion, in which case the spicule 

 resembles the Acamptogorgia type. Sometimes there are very evident keels on one or both 

 sides of these expansions; but the ordinary type in this species has but one often lobed or 

 slightly frilled plate, which is exposed on the surface of the calyx. There are also a number 

 of ordinary spindles, clubs, etc. 



Color. The colony (in alcohol) is a rather dull yellow, the axis is brown and the spicules 

 bright yellow. 



General distribution. The type specimen was from Callao, Peru.

Colony flabellate in form, 10.5 cm. in height and 8.5 cm. in diameter. The main stem 

 is erect and sinuous, and gives off a pair of unecpial and .subopposite branches about i cm. 

 above its base, and another subequal pair 7 mm. above the first. The branches above this are 

 lateral but unecpially disposed. The main branches are unequally divided and give oft branchlets 

 to the fourth order. The main stem is slightly flattened basally, but the remainder of the stem 

 and branches are round and approximately equal in thickness. The basal part of s-tem is 3 mm.
