of the branches. The largest specimen is 5 inches high and the same 

 in breadth ; diameter of the main branches -15 ; of the branchlets -08. 

 Color bright red, the surface sometimes fading to yellowish red. 



The spicula are mostly light purplish red, mixed with a few light 

 yellow ones ; polyp-spindles light amber-color. The longer double- 

 spindles resemble those of the preceding species, but are relatively 

 larger and more acute. They are closely covered with large warts, 

 with a rather wide median space. The stouter double-spindles are 

 similar, but blunter at the ends ; with them are many small, white 

 double-spindles with only one wreath of warts near the ends. The 

 longer double-spindles are -138'"'" by -048, -132 by -054, -120 by -048, 

 •120 by -042, -114 by -039; stouter ones -132 by '060, -108 by -043,

This species is allied to the last, and branches in a similar manner, 

 but has thicker branchlets, with larger and more widely separated 

 verrucas, which are less prominent and open outward. The branchlets 

 are scarcely quadrangular, the spicula different in form, and the coa- 

 lescence of the branches, common in this, is very rare in X. ramulus.

Corallum loosely ramose, the branchlets subpinnate, producing an 

 open, shrub-like form. The trunk divides near the base, in the orig- 

 inal specimen, into two main branches and these again fork. The 

 branches give off pinnately, at distances of half an inch to an inch 

 apart, slender branchlets, which are flattened and spread at nearly 

 right angles, varying in length from a quai'ter inch to three inches 

 before subdividing, as some of them do, into secondary pinna?. The 

 main branches are round, but the branchlets are much compressed and 

 slender. The cells form rather large verruca?, which are enlarged at 

 base and quite prominent, not crowded, and arranged in two alterna- 

 ting rows on each side of the main branches, but in only one row on 

 each edge of the branchlets, which therefore appear serrate on account 

 of the broad-based cells. There is a very distinct sulcus on the larger 

 branches. The specimen is 5 inches high and 6 broad; diameter of 

 the main branches '10; width of branchlets "06. Color bright red. 



The spicula are all bright red, resembling those of X. ramulus, but 

 larger and relatively stouter. The longer double-spindles are long,, 

 covered with large papilla? or warts, those next to tlie median space 

 largest. Stouter double-spindles decidedly blunt, closely covered by 

 large, rounded, rough warts. Polyp-spicula slender, bright yellow.
