Cells ovate, free and sub-erect above, surface uneven, punctured ; orifice 

 arched above, contracted towards the lower part, surrounded by a much 

 raised, infundibuliform or sub-tubulose peristome, which is entire in the 

 sterile and deeply emarginate above in the fertile cells; ovicell small, 

 recumbent, immersed. 



Hab. — Madeira, /. T. J.; Mediterranean, Savigny, 



From a general resemblance to Savigny's figure, I venture 

 to refer the present species to Audouin's L. Mangnevilla ; but 

 at the same time, since some doubt may be entertained on the 

 subject, I have thought it best to give a figure and diagnosis 

 of the Madeiran form. 



In the figure, the surface is incorrectly represented more 

 as if it were granular than merely uneven and punctured.
