404 Verrill, Notes on liadiata. 



small, short spicula have the form of douhle-heads, with a well-defined 

 median space, and two closely crowded whorls of small warts on each 

 end. Cross-shaped spicnla occasionally occur, having acute points, 

 with well-separated rough warts. 



The longer double-spindles measure -144""" by '042, -132 by '048, 

 •120 by -048, -120 by -042, -114 by '054 ; the stouter ones -096 by -052, 

 •090 by -054, -078 by '054, -078 by -042, -072 by '039; the double- 

 heads -048 by -033, -054 by -036, '042 by -024. 



The specimens from Zorritos belong to this variety but are dwarfed. 

 Height 3 or 4 inches, branchlets '25 to '75 long, -08 in diameter. Color 

 purple, with the surface streaked and stained with yellow. Spicula 

 much like those of the specimen described above.

This species is closely allied to L. rlgicla, yet the typical specimens 

 from Cape St. Lucas have a very different appearance, due mainly to 

 the larger, straight, cuspidate branchlets, and the peculiar color, which 

 is seen, however, to a less extent in some specimens of L rigida. 

 Possibly it may ultimately prove to be only a variety of that species, 

 when a larger series of specimens can be examined. Owing to the 

 doubtful affinities of the peculiar specimen from which the spicula 

 above described were taken, no reliable conclusions can, as yet, be 

 based upon the slight diiferences observed in the spicula. 



Leptogorgia Caryl Veniii. (Litigorgia fucosa, 1st Ed.). 



Plexaura fucosa VerriU, Bulletiu M. C. Z., p. 45, (iion Val.). 



Corallum dichotomous, subdividing some distance above the base. 

 Terminal branches stout, two to four inches long, as large as the main 

 stem, nearly round. Cells very little raised, scattered on all sides of 

 the branchlets. Color bright orange-red. 



Sj)icula yellowish red. Longer double-spindles rather stout, scarcely 

 acute, with a wide median space ; two or three whorls of large, com- 

 pound, rough warts on each end, those nearest the middle much the 

 largest. Stouter double-spindles short and blunt, with a wide median 

 space, each end with two or three crowded and usually somewhat 

 confused whorls of large rough warts, forming a large terminal cluster. 

 Some approach the form of double-heads, with a narrow median space 

 and a large cluster of closely crowded warts on each end. Other 

 " heads " are shorter, lack the median space, and are entirely covered 

 with crowded warts. Crosses, with four short, roughly warted 

 branches frequently occur.
