Verrill, Notes on Radiata. 453 



px five times dichot onions; the branchlets diverge frequently at right 

 angles and are mostly veiy crooked, usually tapering somewhat to the 

 obtuse tips, 1 to 3 '5 inches long. One small specimen is simple for 1-5 

 inches from the base and then gives off' subpinnately from each side 

 seven crooked branchlets, which are mostly alternate on the opposite 

 sides and from '3 to "5 of an inch apart ; the lower ones diverge nearly 

 at right angles and some of them branch near the end, or at '75 to 

 1*25 of an inch from their bases. 



The verrucse are rather small, low, rounded or subconical, distantly 

 scattered, opening outward, ai-med at the summit with a few small, 

 slender, projecting spinules, their sides, like the ccenenchyma, liaving 

 a very finely granulous surface, appearing smooth to the naked eye. 

 Ccenenchyma rather thin, firm, filled with very small rough spicula. 

 Axis dull brownish yellow, wood-like in appearance, its surface 

 strongly furrowed longitudinally, giving it a corrugated or irregu- 

 larly fibrous appearance. 



Color a uniform dull yellowish or buff". Height of largest specimen 

 5 '5 inches; breadth 5 ; diameter of largest branches "20; of terminal 

 branchlets '10 to '15 ; height of verruca? "03 to '04 ; diameter "04 to '05. 



The spicula are white, much smaller than in the preceding species. 

 The larger ones consist of more or les^ stout, very roughly warted 

 spindles, which ai-e often irregular and usually acute ; and of long, slen- 

 der, very sharp spindles, with very small, distant warts or spinules. 

 The small spicula of the ccenenchyma are of various forms of ci'osses, 

 heads, double-heads, clubs, short spindles, etc., all of which are very 

 roughly warted. The larger rough spindles measure -375""' by •! 25""",

This appears to be quite distinct from the last in its smaller and 

 more numerous branches, smaller and less prominent verruca?, and
