everted, and all turned one way. Ellis figures some oval- 
shaped vesicles, arising from the base of the cells, speckle®, 
with a small tube at the back ; this is of rare occurrence, l 01 
I have never seen it. , 
I am inclined to think that two species have been included 
under this name. In Turton’s edition of Linnmus, vol. 
page 680, it is said, “ Denticles alternate with a single ha'}, 
on the top of each,” ami in Stewart “ denticles alternate! 
whereas this species lias only a single row of cells wlii® 
are all turned ono way, and Lamouroux by placing it lfl 
Eucratea, makes it to have only one row, “ Polyp' 01 " 
phytoide, articule ; cheque articulation composite d’une seu> 
cellule simple el arquee ; overture oblique;” and Flernide' 
“ Branches consisting of a single row of bent cells.” I ha v ,° 
made these references because I have met with two sp® cl | 
mens, of what appeared at the lime to be deform® 
specimens of this species, in which, although the cells mU> 
be said to be uniserial, yet their bent necks and apertur" 5 ' 
were alternately turned in opposite directions, and hcn®°. 
might be said to be alternate, and the bristles, instead 
being above, were benealh the apertures, which won 
nearly correspond to the description of Linnaeus and Ste«' ar ’

This is a very minute species, and is in its appeara 111 '''.' 
more singular, perhaps, than any other of the family* 1 
confervoid, calcareous, erect, aud rises from minute tub ® 0 t 
fibres which trail over the fueus on which it grows and r . 
it to the spot. The first cellule which arises from the r ,, 
is long, tubular, slender, with an everted neck, very 1,1 j, 
resembling a cell of the Iasi described species. It is l 11 . 0 ( 
and irregularly branched and composed of a single s erl ^ ( .||s 
cells arranged longitudinally one above another. Tb® . |e
