Murieea appi'essa Verrill. 



Corallum broad, flabelliform, very brandling, even to the base. The 

 trunk divides at about half an inch from the base into two, three, or more 

 principal branches, which rapidly diverge and subdivide in an irregular- 

 ly dichotonious or subpinnate manner. Branchlets .-lender, cylindrical or 

 slightly clavate, with obtuse tips, one or two inches long and one eighth of 

 an inch in diameter. Cells small, thickly crowded on all sides of the branches, 

 rounded, closely appressed, the summits curved inward; exterior densely 

 covered by small oblong spicula. Color, in alcohol, dark umber-brown. — 

 Panama; J. II. Sternberg.

Svx. Ellisella juneea Gray. — Indian Ocean. 



Juncella extans Verrill. 



Tall and simple, with the very prominent verruca? curved inward and ar- 

 ranged crowdedly in a band on each side of the axis, leaving a wide naked 

 space on each side. Color white. Axis grayish white, stony and rigid. — 

 Fayal, Azores ; C. Dabney. 

 Isis hippuriS Linn. — East Indies. 



Parisis Verrill. 

 Corallum irregularly branching, nearly in a plane. The axis consists alter- 

 nately of calcareous and suberbus segments, of uniform thickness, traversed 

 by numerous narrow sulcations. The branches originate from the calcareous 

 segments. Coenenchyma persistent, rather thin, somewhat membranous, w itb 

 a rough surface. Cells prominent, arranged irregularly on all sides of the 

 branchlets, but often absent on the median surfaces of the larger branches. 



Parisis fruticosa Verrill. 



Large, flabelliform ; the principal branches arising irregularly along the
