[ularly distributed on all sides "t the colony, being somewhat more numeróus on the sides 

 i and branches and most closely aggregated on the club-like branch terminations. 

 \ var) from 3.3 mm. t < » 7 mm. trom summit to summit. 



ndividual calyces are low but evident verrucae varying greatly in si/e. ,\ typical 

 one measures 1 .; mm. in height and 3.5 mm. in diameter. There are eight sharply defined 

 rinal lobes which c-losc over the retracted polyps, the slit like spaces between the lobes 

 forming an eight-rayed star. The walls of the calyces, like the general coenenchyma, are filled 

 with oval, densely tuberculate spicules. The polyps are completely retractile and the dorsal 

 surfaces of the tentacles are completely encrusted with oval, very tuberculate spicules. 



\ transverse section of a branch shows a comparativel) thin coenenchyma in which is 

 a very regular series of many water-vascular canals. The axis is spongy in texture and filled 

 with a felted mass of rather long, slender, rod-like or needle-like spindles with their surfaces 

 ornamented with rather distant thorny points. The axis is penetrated with numeróus canals 

 of various sizes. 



Spicules. The spicules are of two main types. 1 the rod-like thorny spindles of the 



axis. These are not so delicate as in Solenocaulon, and the thorns are comparatively larger. 

 Many are spindle-shaped rather than rod-like. The second type is a minute, oval. sometimes 

 round s] dciile with very prominent vVrruca- which are usnally arranged in symmetrical whorls 

 and aKo cap the ends. Commonly there are two such whorls and two caps. Nearly all of the 

 spicules are one or the other of these two types, or easily recognizable modifications of them. 



Color. The specimen is creamy white throughout.

Specimens in a very fragmentary condition. The one described is a part of a branch 

 m. Ion- and with a diameter of S mm. approximately round in section. The surface is 

 almost covered with papilliform calyces resembling those of Eunicea. 



The individual calyces are club-shaped, pointed obliquely upward and outward, averaging 

 about ;.; mm. long and 1.8 mm. in diameter near the distal end. They are adnate to the 

 branch throughout th<-ir length and their margins terminate is S not very conspicuous lobes 

 which an- tightly closed over the retracted polyps. The calyx walls are filled with regular 

 spindles disposed longitudinally. The polyps are entirelj retractile and appear to be devoid 



.\ 'ion of a branch shows a rather thin coenenchyma and an axis cylinder 



omp< purple and deep violet spicules embedded in a horny matrix. The axis is hollow 



ighout the length of all of the fragments, having a tunnel apparentlj made by a smal] 



bivalve mollusk, one of which was found in situ. The tunnel is not round, but flat, to fit the 



mollusk, and the greater part of the axis lias been absorbed or in some manner removed,
