36 STYLASTER. 



Stylaster punctatus Porur. 



Corallinii siihflubellate, slender ; ea'nenehyina smooth, liiicly ])uiictate 

 witli little poi'es, looking under tlio 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 tlie genus. Calicles alternate, 

 subpedicellate, but very little lai-ger than the pedicel, always conhned 

 to two sides of the branches, u])per lip not obliterated, except in tiie 

 axilhx) of the branchlets, where the outer lip also becomes appressed 

 and scahdike. Fossa deep and Uiirrow, columella deeply seated. Septa 

 twelve, as usual in the genus. Color light purple. It diflers I'lom 

 S/. roscii,^, which it resend)les most, by its slenderer branches, smaller 

 and less ])rominent calicles, more distant from each other, and strictly 

 lateral ; deeper fossa, smaller and more concealed coUnnella. 



One specimen in 9 fathoms off Orange Key, and another in 31-J 

 fa,thoms oft" Double-Headed Shot Key, a very unusual rangi>. 1 su|)- 

 pose the shoaler locality to be the true iial)itat, as the cast in iWo 

 fathoms produced a great mixture of shoal and deejMvater 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 

 imknown depth. 



Stylcister complanatus I'm hut. 



Sli/lasler comptanalus Pouitr. Hull. Mns. Coinp. Zool., No. 6. 

 Slenohetia coniplanata Kk.N'T. Ann. & Mag. Nat. Hi.st, Fubniary, 1870. 



Plate II., ligs. IG and 17. 



Corallum branching, tlahcliatc. not coalescing, slender. Calicles 

 pedicellate, gemmating iVoui tiie edge of the preceding calicle, gener- 

 ally on alternate sides, so as to give a zigzag form to the Ijranches. but 

 souu'tiuu's two or even three corallites rise from the border of tlie 

 ]irecediug. They are directed towards one ol' the faces of the llabel- 

 lum. Calicdcs compressed in the same ])laue, their diameters being 

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

 by the plicated lip raised against the stem. Fo.ssa moderately deep, 

 columella stylilbrm, aiul siuTouuded l)y rudiuieutaiy pali. Spiny 

 am])ulla', chietly confined to the rear side. 



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

 edge to tiie calicde. Tertiary rudimentary septa in the interseptal 

 chambers. 



Color white; s[)ecimens in Mr. K. .Viango's collection, in Havana, 

 delicate ])iuk. 



In 270 fathoms oft" Havana; not found on Florida coast.
