main branch is anterior and gives off a number of lateral bianchlets 

 which are unequally distributed, being from 4 to 25 mm, apart. The 

 calyces are very prominent and are mainly lateral but often anterior 

 in position; but the back of the colony is bare. The calyces average 

 about 2 mm. apart. 



The individual calyces are tubular in form. A typical one meas- 

 ures 2.5 mm. to the top of the infolded tentacles, and 1.3 mm. in diam- 

 eter. Its walls are filled with small fusiform spindles, closely packed, 

 with no definite arrangement. Toward the margin there is a ten- 

 dency to form eight broad shallow longitudinal folds, extending 

 upward over the bases of the tentacles and forming a thick crest on 

 their dorsal surfaces and eight lobes to the calyx margin. The distal 

 parts of the tentacles are completely hidden and bear few if any 

 spicules. 



The spicules are very small short terete spindles, densely tubercu- 

 late, the tubercles forming regular whorls around the body of the 

 spicule. Sometimes there is a girdle without tubercles around the 

 center, forming double spindles or double heads. 



The coenenchyma of the stem and branches is packed with similar 

 spindles, usually longitudinal in position. 



Color: The colony is very light j^ellowish, almost cream color. The 

 axis is dark brown proximally, lightening distally.

Type-specimen.— Csit. No. 30044, U.S.N.M. 



This species seems to be a Leptogorgia according to the definition 

 given by Verrill, but has longer and more prominent calyces than any 

 other species of the genus of which I can find description. 



Genus CALLISTEPHANUS Wright and Studer. 



Colony feebly branched; axis horny and calcareous; calyces dome- 

 shaped; coenenchyma thick; spicules spiny spindles, clubs and half- 

 sided warty clubs. 



CALLISTEPHANUS PACIFICUS, new species. 

 Plate 14, figs. 2, 2a; plate 21, fig. 6. 



Colony flabellate in form, 7.3 cm. high and 6.4 cm. broad, diameter 

 of stem 1.8 mm.; 1.4 cm. above its base the main stem produces two 

 opposite branches, projecting at right angles, but afterwards bent 

 upward. One of these is unbranched and the other bears three 

 branchlets on one side; 1.1 cm. above these the stem bends suddenly, 

 giving off from its convex side another branch; 4 mm. above this it 

 bears a large branch, then an opposite pair and a simple branch on 

 one side. The distance between branches varies from 4 to 11 mm.
