gray or nearly white, due to the large, fusiform, white spicules, but 

 near the axis the interior of the coenchyma is usually purple, due 

 to the internal, fusiform purple spicules. 



Technical description : Colony three to five feet in height, basal 

 trunk 1.5 to 2 inches diameter; it is repeatedly forked, the branchlets 

 long, slender, slightly tapered, round. The calicles are of unequal 

 sizes, rather large, round or oval, with the margins very little or not 

 at all raised. The calicles are usually placed close together.

Plates 15 and 16. 



Type: Taken by the "Blake" at station 318, Lat. N. 31° 48' 50", 

 Long. W. 77° 51' 50", in 337 fms. 



Distribution: Known only from the type locality and the "Ara" 

 specimen, which is many times larger than the type. 



Material examined : One colony, taken in 150 fms., in the dredge, 

 seven miles off Alligator Reef, Florida, March 30, 1926, by the "Ara." 



Color : Unknown. Preserved specimen a rich old ivory, nearly buff. 



Technical descrdption: Colony 20 cm. high, 5 cm. of which is 

 the basal trunk ; the basal extremity is broken off ; the trunk branches 

 dichotomously less than an inch from the base; the branches fork 

 irregularly, unequally and sometimes pinnately; the branches and 

 branchlets curve outward and upward nearly in one plane. They are 

 of much the same size, the terminal branches often being the largest 

 and supporting more calicles. The axis is almost round, brownish 

 in the larger branches ; pale yellowish in the smaller ones. The calicles
