The longest calcareous internode is 6.1 cm. long, while the horny nodes are but i mm. long. 

 The shorter fragment has a thicker axis than the other, their diameters being 2 mm. and 

 1.8 mm. respectively. Both are largely denuded of ccenenchyma, but retain this and the polyps 

 in places. The calyces are rather closely set in irregular spirals, being on all sides of the 

 stem or branch. 



The individual calyces are columnar in shape and usually project at a wide angle from 

 the stem. A typical one is 4.5 mm. in height and 2.5 mm. in diameter. The walls are nearly 

 straight. There are a few transversely disposed spindles near the base, and a row of about 

 eight long spindles extending perpendicularly from the transverse spicules to beyond the margin, 

 around which they form a crown of points. Shorter spindles support the larger ones near the 

 base, as if propping them. The dorsal surfaces of the tentacles are armed with two or three 

 rows of bar-like spicules longitudinally disposed. 



The ccenenchyma of the stem is thin and stripped from most of the specimens. It contains 

 a few spicules in the form of spindles. 



Spicules. These are nearly all slender spindles, pointed at the ends and attaining a 

 length of 3. mm. They differ from the others described in having their surfaces almost perfectly 

 smooth, without verrucae or projecting points of any kind, thus resembling most of the spicules 

 of the pennatulids. The largest of these spicules are those forming the crown of points around 

 the calyx margins. Besides these spindles, there are a few bar-like forms with rounded ends, 

 found in the tentacles. 



Color. The specimens are ivory white, in alcohol. The nodes are dark brown, and the 

 polyps very light brown. 



General distribution. The type locality is Challenger Station 201, off the Philippines; 

 depth 82 fathoms; bottom, stones. 



This species is also found in the Japanese waters. (NUTTING, Mss.). 



The specimen described is labeled * Ceratoisis philippinensis" . This was very likely written 

 by Dr. VERSLUYS during his preliminary studies of the Gorgonacea of the Siboga Expedition. 

 Through his kindness the writer has been permitted to examine fragments of the Challenger 

 types of this species. These agree fairly well with the above description ; but differ considerably 

 from the description in the Challenger Report, having calyces in some instances 5 mm. in height, 

 and with the spiculation as described above. The small spicules are more numerous than in 

 the Siboga material, and the color of the calyces is much darker. The calcareous internodes 

 are longer in the Siboga material than the descriptions of the type would indicate.
