390 Verrill, Notes on Radiata. 



gled. Longer double-spindles covered with numerous, close warts 

 with a narrow but well defined median space, the ends blunt ; stouter 

 ones nearly as large and with similar warts. The longer double-spin- 

 dles measure -102'"™ by •042'"'", -096 by -042, -084 by -042, -084 by 

 •036 ; the stouter ones -084 by -048, -072 by ^042, -072 by '036, •OGO by 

 •036, -048 by '024; the polyp-spicula •OeO to "084 by -018 to -024.

This species resembles L. Agasslzli more than any other species. 



Leptogorgia eximia Ven-m. (Litigoegia exdiia, 1st Ed.). 



Plate V, figure 20. Plate VI, figure 2. 



Frond broad and rounded, composed of slender, round branches, 

 which are openly riticulated throughout, except the short terminal 

 branchlets at the edges. There is no distinct midrib, all the branches 

 being nearly uniform in size, except very near the base, which rapidly 

 subdivides into a large number of nearly equal primary branches, not 

 distinct from the secondary. Occasionally secondary fronds start out 

 from the sides of the frond, and one specimen has iiTegular, crooked, 

 simple branchlets, arising from the sides, with a hollow axis, apparent- 

 ly the habitations of some parasite. 



The reticulations are quite irregular in size and form, frequently 

 squarish or rhomboidal, from "20 to ^25 of an inch across, but more 

 commonly with about the same width and three or four times higher 

 than wide. Many short free branchlets often project into the larger 

 meshes. The terminal branchlets are sometimes free for an inch, but 

 usually much less. The cells are small and usually closely arranged 

 on all sides, forming small, rounded verracese, which are slightly prom- 

 inent. Color bright red or vermilion. The largest specimens are 

 about 10 inches high and broad; diameter of branchlets "Oe. 



Spicula bright red, with a few light yellow ones ; those of the polyps 

 light yellow. The longer double-spindles rapidly taper to the acute 

 ends, and are covered with rather large warts, which are not crowded ; 

 stouter ones much smaller, blunt at the ends, with fewer and more 

 crowded warts. Polyj)-spicula very slender, with few distant warts. 

 The longer double-spindles measure -138'""° by -060, ^132 by ^054, •132 

 by -048, ^120 by -054, ^108 by ^048; the stouter ones ^108 by •054, 

 •090 by -048, •OBO by •OSO ; double-heads -060 by ^048, ^038 by ^036; 

 polyp-spicula '072 to -120 by -012 to 024.
