Original dei<crij)tii>n.—Pvoiessor Verrill's description is as follows: 



Coralluiii encnisting rocks, forming clusters of crowded cups, about an inch higli; some of tlie 

 corallitcs are laterally united even to the top, others are separated about an eighth of an inch and 

 rise nearly a quarter of an inch above the ctenenchyraa. The exterior of the corallites is obscurely and 

 closely costate, and covered closely with rough granulations. Septa in four cycles, the last imperfectly 

 developed. Primaries much thicker than the others, very narrow at the top and not projecting above 

 the wall, which is much thiclcened, on their inner edges slightly concave, and increasing somewhat 

 in width toward the Ijottoin of the cell, where they join the columella. The secondaries are still 

 narrower an<l thinner, but also join the columella. Those of the third order are ex.remely narrow 

 and often do not reach tlie margin of the wall, and do not join the columella. Those of the fourth 

 order are merely slightly raised costie, very thin and uneven. Columella well <ieveloped, spongy, 

 nearly half as broad as the cell. 



Cells slightly oval, the larger ones about 0.3.5 of an inch in diameter, and nearly the same in depth. 



Color of living polyps, vermilion red.

Prof. W. T. Brigham has sent 2 specimens of a DendrophyUia ( C(Bn<ypsanimid) 

 from Kaneohe, Oahu, depth 3 to fl feet, that differ from the type of D. umnni by 

 their very exsert corallites and jworly developed columella (Plate XLVI, Kgs. 7, 

 la). However, the costa' are similar on corallites of the same length, and I therefore 

 believe that they belong to the same species.

Oriffinal description. — According to Alcock this species is described as follows: 



Colony ilendroid, gemmation taking place near the calicular margin and being alternately 

 distichous or, more commonly, dichotomous leaving the parent calicle immersed and more or less 

 compressed between the two branches, as in Cijathohelia. The openings of the calicles all tend to 

 face one way, and are commonly circular (except in the axils). 



Costal striations all ecjually distinct, in the form of finely scabrous vermicular ridges traversing 

 the whole length of the colony. 



The calicles after budding are little prominent, or even almost innnersed: they are deep and empty 

 looking, owing to the shallowness of the septa. 



Septa ai)proxiinately ecpial, elegantly notching the somewhat tumid margin of the calicle but not 

 exsert, not encroaching on the calicular fossa. They are in six regular systems and three cycles:
