largest, the outer ones close to the ends ; median space rather -n^de. 

 There are numerous much smaller spicula, with a well marked median 

 space, and a whorl of warts on each end, which are more or less con- 

 fused with a cluster of terminal warts. Sometimes the terminal warts 

 form a small terminal whorl. Polyp-spicula light red, slender, acute, 

 slightly papillose. 



The long double-spindles measure •156""" by -048, ■121 by '048, -144 

 by -042, -103 by -030; the stouter ones -090 by '042, -078 by -042, -072 

 by -036; the small ones -054 by -028, -048 by -024, -036 by '024.

 but slightly raised.

Corallum forming large, openly reticulated fans, with stout, sub- 

 parallel, upright branches, and long, oblong or rectangular meshes. 



In young specimens the trunk is divided close to the base into two 

 or more principal branches, wliich give off irregularly numerous bran- 

 ches of nearly the same size, so that the main branches very soon blend 

 with the others and can be traced only for a short distance. The 

 secondary branches and the branchlets start out nearly at right angles, 

 and then suddenly bend upright and become parallel with the preced- 

 ing branches. The cross branchlets project nearly at right angles, 

 connecting the branches together at intervals varying from '5 to 2 

 inches, so that the meshes have openings of these lengths, and about 

 •20 to -25 wide. The terminal branches are of about the same size as 

 the other branches and free for the distance of one or two inches. 

 The branches and branchlets are often nearly round, at other times 

 compressed in the plane of the frond, or even at right angles to it. 



The cells are small, very numerous, arranged closely in many rows 

 along each side of the branches and branchlets, but nearly covering 

 the latter. They are mostly flat, but occasionally the borders are 

 slightly raised. Median naked space well marked and often having 

 strong longitudinal furrows. Color dull yelloAv, often tinged with 

 purple, frequently stained dark umber-brown in drying. In life, 

 '' brownish yellow to faint salmon, polyps light yellow," — F. H. B.
