pinna?, agiiin sulxlivide, Ijut less regularly. The branclilcts are all 

 of nearly uniform size, slender and short, somewhat flattened and en- 

 larged at the ends, which are tridentate. The cells are very small, but 

 form well marked conical verruca^ arranged in two alternate rows on 

 most of the branehlets, but sometimes forming only single marginal 

 rows on the terminal ones. Tho front and back sides of the branches 

 are destitute of cells, and on the principal ones usually show a well- 

 marked longitudinal furrow. Color bright red, sometimes tinged 

 'with yellowish. Height of the largest specimens 6 inches ; breadth 

 12 ; diameter of the main branches at l)ase '12 of an inch ; of the sec- 

 ondary ones °06 ; of the terminal ones "04 ; length of the terminal 

 branehlets usually about "So, rarely '75. 



The spicula are liright red Avith a few yellow ones intermixed. The 

 longer double-spindles are rather slender, with acute ends, and cov- 

 ered with close warts arranged in about six distinct whorls, besides the 

 terminal clusters ; stouter ones smaller, with blunt ends; polyp-spic- 

 ula bright yellow, slender, with few, distant, small warts or papillae.

This species resembles, in its mode of branching, Eugorgia 3fexi- 

 cana V. and E. Daniana V., but is much more slender and delicate, 

 w^ith a smoother sui-fiice and denser cosnenchyma, and is very distinct 

 in its spicula, its color is also very different. The spicula resemble 

 closely those of L. eximia V. but are somewhat more slender with 

 the warts not so close. The external characters are very different. 



I have named this elegant species in honor of the excellent wife, 

 whose sympathy and encouragement were the chief causes that in- 

 duced me to devote my life to the study of Nature. 



B. Flabelliform, the branehlets mostly coakscent and reticulated, the terminal ones free.

 Corallum forming very finely and regularly reticulated fans, usually 

 rounded in outline. Several flattened main branches arise from the 

 laro-e thickened and very short base and radiate across the fan, sub- 

 dividing so rapidly and regularly that they cannot often be traced
