322 POLYZOA INFUNDIBULATA. 



granules, the aperture wide, circular, with a more or less prominent 

 mucro on the proximal side, and two wide open auricles or projecting 

 loops at the side. In no instance has the trace of any spines been 

 discovered ; but the space between the bases of the cells is occasion- 

 ally punctured. Ovarian capsules in front of the aperture, rather 

 small, rounded, granulous. 



Allied to Lepralia Hassallii. I have dedicated the species to an 

 eminent naturalist, Robert Ball, Esq., of Dublin. 



31. L. COCCINEA, cells shortly cylindrical, rough, raised 

 anteriorly, the aperture mucronated on the proximal and armed 

 with four or five long spines on the distal margin. Dr. Fleming.

Crust in circular spots of an orange-red, yellowish-brown, or, 

 sometimes, white colour, closely adherent, the margin often darker 

 coloured than the centre, and with unfinished cells : cells subcon- 

 fluent, shortly cylindrical, rising towards the aperture, the walls 

 roughish, glistening; the aperture wide, circular, with three denti- 

 cles on the proximal side, of which the middle one is the largest and 

 most prominent, and there are several long filiform spines project- 

 ing from the under lip. These spines are often not to be found in 

 the central cells, but I have always found them in those of the 

 margin : they are four or five in number and of unequal length. 

 On each side of the aperture there is usually a large open loop or 

 auricle, but cells with these auricles and without them are to be 

 seen in most specimens. Ovarian capsules globular, rough. 



Abeldgaard's description is as follows : " Stratum planum cocci- 

 neum. Cellulse confertse, diaphanse, fundo coccineae. Os orbicu- 

 lare, unidentatum, margine denti opposite ciliato. Animal Hydra 

 coccinea tentaculis sequalibus novem. Raro se exserit."
