 It belongs to the DesmosayphvA group. Allman's drawing having evidently been made from the

SERTULARIA STOOKEYI, new species. 

 (Plate V. tin*. H-7. ) 



Tr<>i>li<ix<nii< . Colony consisting of unbranched stems springing from a creeping root-stalk 

 and attaining a height of about one-third inch. Steins constricted basallyand divided into regular 

 internodes. except proximal portion where the nodes become indistinct or obsolete: internodes 

 long and slender, the hydrothecffi being placed in front of the distal half, the nodes being just 

 above the hvdrothecie. Hvdrotheca- strictly opposite, adnate to each other by about the basal 

 one-third of their adcauline wall, the line of juncture being straight: basal portion not distinctly 

 swollen, distal one-half free, a slender cone in shape projecting at an angle of aliout 45 degrees 

 with the stem, and ending in a bidentate margin and two-flapped opcrculum. 



(iniiiiKniiii . (ionangia borne at bases of colonies, large, oval, with a straight narrow collar, 

 wide narrow aperture, and opereuhim; pedicel very short.
