394 Verrill, Notes on Radiata. 



Height of the largest spechnens about 2 feet; breadth about the 

 same ; diameter of branchlets -15 of an inch. 



The spicula are reddish purple and light yellow intermingled, both 

 colors sometimes occurring on one spiculum. Long double-spindles 

 somewhat slender, acute at the ends, with a rather wide median space ; 

 warts distant, forming about three whorls around each end, those next 

 the middle much the largest. Shorter double-spindles thick and blunt, 

 with a wide median space, on each side of which there is a whorl of 

 large thorny warts ; beyond these is a small wreath of much smaller 

 warts, close to the ends, and often confused with the terminal cluster 

 of few small warts. In addition to these there are many much small- 

 er double-spindles, with two well separated whorls of small warts on 

 each end, one of which is nearly terminal and much the smallest. 



The long double-spindles measure •121'"'" by -036, and -108 by '036 ; 

 the stouter double-spindles -384 by -048, -072 by -048, -061 by -048, and 

 084 by -042 ; the small ones -036 by -024.

Leptogorgia stenobrochis, var. Englemanni. (LitigorcxIa, 1st Ed.). 



The original specimen, described by Mr. Horn, and others from Aca- 

 pulco and Panama differ slightly from the ordinary forms from Panama 

 in having smaller and usually less elongated reticulations. The branch- 

 es are also more compressed and in some specimens thicker, though not 

 constantly so. The cells are very numerous, thickly scattered over 

 the whole surface of the branches, but sometimes leaving a narrow 

 median space. They are oblong and slightly prominent. 



The color is reddish brown, yellowish brown, or dull brownish yel- 

 low tinged with reddish. 



The spicula are light yellow and deep red intermingled, and agree 

 nearly with those of the ordinary variety in form, but are smaller. 



D. — Imperfectly flabelliform, the branches pinnate or imperfectly hipinnate, not reticula- 

 ted; iranchlets rather short. Cells someiuhat prominent.
