Colony rudely flabellate in form, 6.7 cm. high and with a spread of 3 cm. The main 

 stem forks 6 mm. above its base into two approximately equal upright branches, each of which 

 is branched in a pinnate manner. These branches send off a very few branchings of the third 

 order, and one twig of the fourth order. The calyces are mainly lateral in position, although 

 a few are scattered along the front and back of the coiony. Their distance from summit to 

 summit varies from 2 to 4.5 mm. There are no terminal calyces. 



The individual calyces vary in shape from subconical to nearly tubular. Some are dome- 

 shaped, in complete retraction of the polyps. A typical one measures 1.2 mm. in height and 

 1.5 mm. in diameter at the base. Their walls are filled with small closely set imbricating cliscs 

 with minutely ctenate edges, each scale having a well-defined darker area in its centre and 

 lighter edges. The polyps are completely retractile, but in many cases they rest with the col- 

 laret immediately above the margin and the acorn-shaped operculum rising well above it. The 

 operculum is composed of the usual typical elements, two bent spindles with a third shorter 

 one lying between their divaricated bases. There are often smaller longitudinal spindles on the 

 distal portion of each tentacle. The spindles do not cover the tentacles, and the opercular 

 flaps leave a rosette-shaped bare space when viewed from above. 



Spie nies. These are of the typical Bcbrycc form, being ronnd dises with an elevated 

 central portion. In shape they greatly resemble a collar-bntton with a very short broad connec- 

 tion between the expanded portions. There are also stars and multiradiate forms based on the 

 typical forms just described ; and a few small spindles, oval dises, etc. 



Color. The colony is very light brown, the axis white, and the spicules colorless. 



General distri bu t i o n. The type was secured from the Gulf of Manaar. 



Several specimens from Station 305 are considerably larger, one being 12 cm. X JO-5 cm. 

 in measurement, and strictly flabellate in form.

Colony obscurely flabellate in form, 8 cm. in height. The main stem is unbranched for 

 3 cm. above its base, where it divides into two approximately equal parts, each of which gives 

 off two branches. One of these latter is anterior instead of lateral in position. The calyces are 

 clistributed over the whole surface of the stem and branches, there being about as many on 

 the front and back as on the sides. They are very unevenly spaced, however, being from 

 2 to 3 mm. apart.
