spinulose. The septo-costae are very tbiii and high, separated by 

 spaces 4 to 6 times as Avide, with few angular teeth. 



In sections (fig. 2c), the exotheca is abundant, coarsely cellular ; 

 the dissepiments are convex and numerous. Singapore (?); Muf<.

Plate XXIX. Figure 3. 



The coral forms broad, thin, contorted, foliaceous fronds, some- 

 times 20 inches (500™™) broad and 10 inches high, while the average 

 thickness of the folise may be 3 to 4™™, becoming very thin and 

 translucent toward the margins, but yet compact and strong. Under 

 side has rather loosely scattered small calicles in some parts, but 

 toward the margins they are absent and the surface is evenly and 

 closely covered with very small, nearly equal cost^e, roughened with 

 minute granules. 



The upper side is roughly echinulate, and bears larger and more 

 pi'ominent calicles, which are rather crowded in some pai'ts, but 

 irregularly arranged, and becoming more scattered toward the mar- 

 gins, where the intervals are often equal to three or four times their 

 diameter. 



The larger corallites are verruciform, 3 to 4"'™ in diameter, with 

 very roughly echinulate septa and costte. 



The septa, in the larger calicles, form three very unequal cycles. 

 The six primaries are much exsert, a little thickened, hispid laterally, 

 and with the edges finely lacerately toothed. Usually the}^ consist 

 of two or three deeply divided lobes, the outer one standing on the 

 outer thecal margin ; the next, just within the calicle, is a little 

 wider ; the third, usually smaller, may represent the paliform lobe or 

 tooth. Those of the second c^^cle are smaller and thinner, but lobed 

 in the same wa}^ Those of the third cycle are very small and 

 narrow, or often rudimentary. 



The septo-costse are numerous, even, and rather close, represented, 

 in general, by rows of small, upright, echinulate or lacerate spinules 

 of about equal size ; toward the margins the costuUie become more 

 elevated, wnth the edge echino-lacerate. 



The columella is usually well developed, finely trabecular or spongy.
