Pearl Islands and Panama, very rare, — F. H, Bradley. 



This species is very distinct from the preceding by its very long, 

 slender, and smaller verrucpe, its longer and sharper spicula, and its 

 thicker branches. The latter character and the closely crowded cells 

 separate it widely from M. his2nda and 31. horrlda.

Corallum dichotomous, sparingly branched, somewhat flabelliform. 

 The main branches arise close to the base and bend outward and up- 

 ward with a wide curve, before becoming perpendicular and sub- 

 parallel. The secondary branches arise from the outward curvature 

 of the primary ones, and quickly become of the same size. The 

 branches are slendei", though the long verrucse give them a rather 

 thick appearance, and gradually enlarge to the tips. The coenen- 

 chyma is thin and but little developed. The cells are rather large 

 and regular, at the summit of very long, rather large, tubular verrucse, 

 which are narrow at base and enlarged to the summit, or siibclavate in 

 form, the sides being covered with long, sharp spicula, which project 

 considerably at the summits. Axis very slender, round and black at 

 base, amber-color and translucent in the branchlets. Color, when 

 dry, umber-brown. 



Height of the largest specimen 4 inches ; diameter of branches, ex- 

 cluding verruca?, "12; length of verrucas "16; diameter at summit "07. 



Spicula yellowish white, mostly relatively large, very long, slender, 

 sharp spindles, often curved or crooked, covered on one side with 

 small, very sharp, conical spinules, on the other with small, very 

 closely crowded, rough warts; ends usually very acute. Stouter spin- 

 dles are numerous, which are frequently irregular in form, often bent, 

 sometimes enlarged, branched, or forked, near one end ; one or both 

 ends often obtuse or truncate. The small spicula are mostly regular 

 warty spindles, acute at each end, but often bent in the middle, and 

 are relatively less abundant than in most species. 



The longer spindles measure 2-60""" by -300, 2-30 by 275, 2*07 by
