Echinogorgia aurantiaca Verriii, pp. 413 and 450. 



The spicula of this species show that it is an Echincxjorgia, pretty 

 nearly allied to K sasappo. The spicula are yellow, mostly large, 

 broad, flattened clubs, or scale-clubs, the smaller end often acute, 

 sometimes blunt, covered with rough warts, the large end usually ter- 

 minating in one or more broad, flat, irregular, rounded scales, which 

 are often lobed, or even subdivided into shai-p, lacerate spinules. 

 With these are many, more or less regular, four-branclied crosses, with 

 rather slender, acute, warty branches ; and various forms of irregu- 

 lar, often branched, warty spindles and compound spicula. 



The clubs and scale-clubs resemble those of E. sasappo figured by 

 Dr. Kolliker in his Icones Histiologicse, Taf xviii, figs. 9,^ and 0,3.

Heterogorgia papillosa Terriii, sp. nov. 



Corallum dichotomous, consisting of few, elongated crooked branch- 

 es, which are two or three times divided. The branches are of nearly 

 uniform size, and bend out in a broad curve at the axils. The termi- 

 nal branchlets are from one to three inches long without division, and 

 blunt at the end ; like the branchlets they are round and crooked, 

 covered on all sides with prominent papilla-like verrucje, which are 

 mostly eight lobed and open at summit. The lobes of the a' errucie 

 are supported by long slender, sharp, curved s})icula, which project Init 

 little from the surface. The lower parts of the verruca; and the sur- 

 face of the coenenchyma are smoothish, and consist mostly of quite 

 small, rough spicula. The axis is rigid, grayish, and wood-like in 

 appearance, the surface showing an interwoven fibrous structure; in 

 the branchlets thick, soft, and yellowish. 



Color yellowish white, throughout. 



The only specimen obtained is 5 inches high ; 3 broad ; diameter of 

 branches and branchlets •lO to •U; height of largest veiTUcaa •05.
