frond and attached to it vertically by one edge, but they soon bend 

 around laterally and become parallel to the primary frond ; other 

 fronds often arise from the secondary ones, especially from the i)art 

 where the bend occurs, and spread in the opposite direction. In 

 some specimens all the secondary fronds, often amounting to a dozen 

 or more, are thus united together, leaving between them large square 

 or oblong spaces, often open both from above and below. In one 

 specimen the fronds are numerous, more or less imited together and 

 spreading outward in all directions, while the upper sides are prolife- 

 rous and give rise to many small fronds, thus producing a large and 

 pretty regular rosette. 



These specimens have slender branchlets and small meshes. The 

 color is bright red or purplish, mingled with yellow. 



Leptogorgia pulchra, sp. no v. 



Corallum reticulated, flabellifoi'm, either simple and extending in 

 one plane, or composed of several fan-shaped fronds arising from the 

 sides of the primitive one nearly at right angles and then becomino- 

 parallel. The trunk usually divides close to the base into several 

 principal branches which subdivide rapidly and soon lose themselves 

 among the reticulated branchlets. The meshes are variable in form 

 and size, but commonly angular with rounded corners, often squarish, 

 frequently higher than broad. The branchlets, in the typical form, 

 are rather thick, squarish, with prominent rounded verrucae, arranged 

 in about two rows on each side, and rather crowded, but in the slen- 

 der form fewer and more distant, and often but slightly elevated. 

 The cells, when open, are mostly slightly bilobed. 



Color light or deep reddish or purplish and usually tuiged with 

 yellow or orange, often yellowish red or brick-color, or various shades 

 of reddish brown. 



Height of the lai'ger specimens 8 to 15 inches, generally broader 

 than high ; diameter of the branchlets, in the best grown specimens, 

 about -08, in some cases the branchlets vary in the same specimen 

 from '05 to -10, sometimes they are slender throughout and not more 

 than '05 in diameter. 



The spicula are deep red and bright yellow, or orange-yellow, 

 mingled usually in about equal numbers. The longer double-spindles 

 are rather slender, oblong fusiform, rather obtusely pointed, with a 

 pretty broad median space and about three well separated whorls of 

 low crowded warts on each end, and small terminal clusters. The 

 stouter double spindles are similar, but more oblong in form and 

 blunter, with about two crowded whorls and a terminal cluster of
