larger, and stouter, and less acute. In external appearance it also 

 resembles the slender variety [exilis) of the preceding species, but 

 the spicula are much larger, more regularly fusiform, and much more 

 acute, with comparatively few of the short blunt forms. 



Leptogorgia labiata, sp. nov. 



Leptogorgia ramulus, var. (page 396). 



Of this form, hitherto regarded as a northern dwarfed variety of 

 L. ramulus, I have more recently seen additional specimens from 

 other localities, all of which present the same characters, both of ex- 

 ternal appearance and spicula. I am therefore led to regard it as a 

 distinct species. 



It is low and densely branched, rigid, the branchlets short, thick, 

 squarish, generally blunt, sometimes clavate, but often obtusely 

 pointed. The verrucae are conspicaous, elevated, rounded, closely ar- 

 ranged in about four longitudinal rows, divided at the summit or on 

 the upper side into two lateral lobes or lips, which form the borders of 

 the oblong cells. 



The color is red or brownish, generally more or less tinged with 

 yellow, especially around the cells. 



The largest specimens seen are about five inches high and four 

 broad; the terminal branchlets "25 to 1 in. long; about "12 in diam- 

 eter. 



The spicula are somewhat larger than those of L. ramulus, and de- 

 cidely stouter and more rounded at the ends, with more crowded 

 warts, which usually form a rounded terminal clustei*. They are rose- 

 red and light yellow.

Leptogorgia exigua, sp. nov. 



This form I have formerly regarded as a dwarf variety of L. cuspi- 

 data, but having recently seen numerous specimens from several 

 widely separated localities, I am led to regard it as a peculiar species, 

 allied to L. cuspidata and L. rigida. 



Although quite variable in color and somewhat so in form, it never- 

 theless always has characteristic features by which it may be easily 

 recognized. The color is really less variable, when closely examined, 

 than it would seem to be at first sight. It is a mixture of purplish 

 red and yellow in varying proportions, the yellow spicula being 

 generally more or less concentrated around the cells, and often ting-
