Readily distinguished by its lax branches, and distant, slender, 

 flattened branchlets, serrated by the distant, uniserial verrucas.

Corallum somewhat flabelliform, low, subpinnately branched, the 

 branchlets ascending, not coalescent. The branchlets ai'e nearly round 

 and usually curve outward at first. They are from 1 to 2 inches long, 

 before branching, and from '08 to '10 thick. Cells flat, scarcely rising 

 above the general surface, arranged in about three rows along each 

 side of the branchlets. The apertures in contraction often appear 

 stellate. The naked median region is quite narrow. Color reddish 

 purple, often with a narrow yellow streak along the centre of the 

 median space. Height 4 to 6 inches. 



The spicula are mostly reddish purple, some are half yellow, others 

 entirely so. The longer double-spindles are slender, scarcely acute, 

 witli a wide median space, which is bordei'ed by two whorls of large, 

 rough, distant warts. Close to each end and distant from the preced- 

 ing, there is a much smaller whorl of small warts, while the ends ter- 

 minate with two or three similar small warts. Stouter double-spindles 

 thick and blunt, with two wreaths of warts on each end, closely 

 crowded together, those next the narrow median space much the larg- 

 est. Polyp-spicula slender, light yellow, with few, small, distant 

 papillae. Compound cross-shaped spicula occasionally occur, which 

 have short blunt rays, with rough, irregular warts. The longer double- 

 spindles measure -108 by •048'"'", '090 by -042, -084 by -040, -084 by 

 •036; -096 by •036; stouter double-spindles ^096 by -048, •072 by -036, 

 •078 by ^042, ^084 by ^048; the crosses ^072 by -006, and -054 by ^048.
