36 STYLASTER. 



Stylaster punctatus Pourt. 



Corallum subflabellate, slender; ccenencliyma smooth, finely punctate 

 with little pores, looking under the lens like eggshell. These pores are 

 present in all the family, as stated before, but they are more conspicu- 

 ous in this species than in the others of the genus. Calicles alternate, 

 subpedicellate, but very little larger than the pedicel, always confined 

 to two sides of the branches, upper lip not obliterated, except in the 

 axillae of the branchlets, where the outer lip also becomes appressed 

 and scalelike. Fossa deep and narrow, columella deeply seated. Septa 

 twelve, as usual in the genus. Color light purple. It differs from 

 Si. I'oseus, which it resembles most, by its slenderer branches, smaller 

 and less prominent calicles, more distant from each other, and strictly 

 lateral ; deeper fossa, smaller and more concealed columella. 



One specimen in 9 fathoms off Orange Key, and another in 315 

 fathoms off Double-Headed Shot Key, a very unusual range. I sup- 

 pose the shoaler locality to be the true habitat, as the cast in 315 

 fathoms produced a great mixture of shoal and deep-water species. 

 The locality is at the foot of a steep slope washed by a strong current. 

 I have also seen it in Mr. R. Arango's collection, in Havana, from an 

 unknown depth. 



Stylaster complanatus Pourt. 



Stylaster complanatus Pouut. Bull. Mus. Coinp. Zool., No. 6. 

 Stenohella conipkinata Kknt. Ann. & Mag. Nat. Hist, February, 1870. 



Plate II., figs. 16 and 17. 



Corallum branching, flabellate, not coalescing, slender. Calicles 

 pedicellate, gemmating from the edge of the preceding calicle, gener- 

 ally on alternate sides, so as to give a zigzag form t^ the branches, but 

 sometimes two or even three corallites rise from the border of the 

 preceding. They are directed towards one of the faces of the flabel- 

 lum. Calicles compressed in the same plane, their diameters being 

 1 mm. and .7 mm.; on the larger branches the calicle becomes hidden 

 by the plicated lip raised against the stem. Fossa moderately deep, 

 columella styliform, and surrounded by rudimentary pali. Spiny 

 ampulla?, chiefly confined to the rear side. 



Septa twelve, rather exsert, and forming a plicated or scalloped 

 edge to the calicle. Tertiary rudimentary septa in the interseptal 

 chambers. 



Color white ; specimens in Mr. R. Arango's collection, in Havana, 

 delicate pink. 



In 270 fathoms off Havana ; not found on Florida coast.
