Echinogorgia aurantiaca Verrill, pp. 4i3 and 450. 



The sj^icula of this species show that it is an Echinogorgia, pretty 

 nearly allied to E. 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 sharp, lacerate spinules. 

 With these are many, more or less regular, four-branched 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 Verriii, 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 brauchlets 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 verrucse 

 are supported by long slender, sharp, curved spicula, which project but 

 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 bi'oad ; diameter of 

 branches and branchlets 'lO to '14; height of largest verructe •05.
