series, diaphanous, dotted with white. Calicle circular, margin entire 

 or nearly so, above slightly striate without ; fifteen to sixteen larger 

 lamellae alternating with smaller. Guadaloupe, West Indies (Lesueur, 

 Jour. Acad. Nat. Sci. Philad., i. 179, pi. 8, fig. 10; Mem. du Mus., 

 vi. 273, pi. 15, fig. 1 ; Lamk., 2d ed. ii. 350, No. 6 a.) 



C. pocillum. (Dana.} Turbinato-cylindrical, four and a half lines 

 broad at top, and three high ; exterior striate half way to the base and 

 granuloso-scabrous, lamello-striae nearly equal; twelve lamellae larger, 

 very broad and exsert, rounded above, granulous ; three intermediate 

 smaller, and one-half narrower. West Indies. Plate 30, fig. 8, na- 

 tural size. 



C. dilatata. (Dana.} Turbinato-cylindrical, three lines high, and 

 the same in breadth at summit; twelve lamellae larger, quite broad, 

 subacute at apex, a little exsert, and very prominent on the exterior 

 halfway to the base; the intermediate three, much narrower, nearly 

 equal, and scarcely at all prominent on the exterior ; the lateral sur- 

 face of the calicle hence smooth, except the twelve large carinating 

 lamellae. Barbadoes, West Indies. Plate 30, fig. 9, calicle, natural

GENUS VIII. DENDROPHYLLIA. BLAINVILLE. 



CaryvphyUida. aggregato-gemmatce, patrio-ramoscz, arborescentes ; ore 

 bnge exserto. CoraUa subcellulosa ; caliculis cylindrids ; lamdiis in- 

 clusis inesquaKbus ; celldprofundd,fundo latd ; extus levibus aut subti- 

 liter striatis. 



Aggregato-gemmate, patrio-ramose, arborescent ; polyp-mouths long 

 exsert. Coralla subcellular ; calicles cylindrical ; lamellae included, 

 unequal ; cell deep, broad at bottom ; exterior smooth or fine striate. 



Like the Madreporae, the Dendrophylliae bud from an apical polyp, 

 and their forms are consequently dendroid, or in imitation of trees, as 

 the name suggests.* Some species attain a height of five or six feet. 



* From the Greek SivSgw, a tree.
