The spicules of the polyp-calyces and coenenchyma are smooth fluted rods, 

 perfectly tmnsparent. Those of the stem are on an averaoe 0-22 mm. in lenoth 

 by 0-015 mm. in breadth; those of the calyx wall are from 0-4 to O'S mm. in 

 length by 0-15 mm. in breadth. 



The colony is colourless, except for the stomodseum, which is blackish-brown 

 in colour. 



This specimen agrees closely with the specimen described by Kolliker. 

 Locality : Station 235 ; 14° 13' N., 93° 40' E. ; 370-419 fathoms.

A large number of specimens, mostly broken and slightly damaged, are 

 placed in this species. A representative example was 350 mm. in length, with a 

 breadth of rachis about 1*25 mm. 



It consists of a stalk (100 mm.) and an elongated quadrilateral rachis. 

 There is no difference between the stalk and rachis, apart from the presence 

 of the autozooids. 



The axis is c^uadrangular with hollow sides, thus giving the stem, which 

 varies from 07-1 -5 mm. in diameter, a quadrangular grooved appearance. 

 Towards the basal end the stem diminishes and then swells, and forms a some- 

 what club-shaped enlargement which is usually slightly curved. 



The rachis is quadrilateral and long, having the autozooids arranged in 

 groups, each group consisting of two irregular rows of three to four polyps. 



The calyces are produced into eight sharp teeth— the tips of bauds of spicules. 

 On the upper part of the calyx, the spicules lie for the most part longitudinally, 

 but towards the basal portion they are more irregular and are often obliquely 

 transverse. Numerous siphonozooid-like bodies, white in colour in marked con- 

 trast to the dull grey of the autozooids, occur among the bases of the latter, 

 principally in a somewhat broken single line on the metarachidial surface. They 

 are furnished with eight short lobe-like projections at the tip, and rise to a height 

 of 1 mm. 



The height of the autozooid calyces varies from 3-5 mm., and the diameter 

 from 1-1 "5 mm. 



The colour of the rachis is yellowish to whitish, the basal portion of the 

 calyces is also whitish, while the upper portion is bluish-black to a dull grey. 



The ova are fairly abundant, and embryos were found with a slightly brown 

 outer coating and a yellow interior with a large cavity. 



The spicules are long slender fluted rods, blunt or pointed at the ends, and 

 often slightly curved at one end. The following measurements were taken of 

 length and breadth in millimetres : 



0-8x0-04; 0-7x0-035; 0-4x0-02.
