3G BULLETIN OF THE 



Within the margin there are several transverse or circular rows of long, slender, 

 pretty regularly curved, or bow-shaped, warty spicula, which surround the upper 

 or marginal part of the partially retracted polyps, at the bases of the tentacles, 

 which are themselves strengthened externally by two convergent rows of simi- 

 lar, but less curved spicula, so arranged as to form eight convergent /\ -shaped 

 groups over the contracted and incurved tentacles. 



The ccenenchyma is thin, not at all spinose, and filled with small, very irreg- 

 ular, rough spicula, many of which are crooked ; these spicula give the sur- 

 face a rather finely and roughly granulous appearance under a lens. The axis 

 is slender, soft and dark brown, and shrinks much when dried. 



In life the color is Kght orange or salmon. In alcohol it becomes dark gray- 

 ish brown or umber-brown. When dried the color is often dark brown or 

 nearly black. 



One of the larger specimens is 280 mm. (about 11 inches) high; breadth, 

 90 mm. ; diameter of main stem, 3 mm. ; of branchlets, 1 to 1.5 mm. ; of 

 calicles, 1 mm. The variety with stouter branches has branchlets 2 to 4 mm. 

 in diameter, including the calicles. 



The large spicula around the edge of the calicles (Fig. 5 a, c, d, e) have a 

 large, broad, flat, variously and deeply lacerately lobed and incised, imbedded 

 basal portion, and a rather short, moderately stout, acute, somewhat rough or 

 warty terminal portion, which projects from the surface. The basal portion is 

 frequently longer than the point, and often broader than long ; it is jialmately 

 divided into tliree to six, or more, irregular main divisions, which are very 

 unequal in size and breadth, and variously subdivided and lobed ; some of the 

 lobes may be broad, and others narrow, some acute, and others truncated or 

 obtuse, and not unfrequently they coalesce, enclosing irregular openings. 

 Some of these spicula measure 1.14 by .57, .95 by .38, .84 by .61, .82 by .48, 

 .76 by .66, .76 by .32, .66 by .28, .61 by .32, .57 by .48, .57 by .32 mm. 



With these are other smaller, rudely oblong, flat spicules (Fig. 5 a, g), which 

 have no projecting point, or only a very short one, but are rudely and strongly 

 lobed, along the sides and at one or both ends, the lobes being more or less 

 sharp, rough and incised. These are variable in size ; some are .76 by .38, .52 

 by ..34,50 by .16 mm. 



Just inside the margin of the calicles there are several transverse or circular 

 rows of long, slender, roughly warted spicules (Fig. 5 a,/), tapering and acute 

 at both ends, and curved in the middle ; these form a continuous band or ring 

 around the base of the free part of the polyps. The larger of these measure 

 ] .28 by .06, 1.05 by .095, 1.05 by .06, .82 by .07, .82 by .05 mm. Above tliese 

 there are eight convergent, triangular or /\ -shaped groups of similar long, fusi- 

 form, warty, mostly crooked spicules, but they are not so strongly nor so regu- 

 larly curved, the bend being usually nearer the proximal end ; these correspond 

 with the stems of the eight tentacles ; some of them are divided at tlie base 

 into two lobes or rough branches. The larger of tliese measure 1.24 by .07, 

 1.08 by .08, 1.01 by .07, .95 by .07, .86 by .08 mm. ; one of the long ones 

 with forked base is LOS bv .06 mm.
