292 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
w»), With wavy wings 8 to 20 » wide along the edges, the margins of the wings 
broadened out and more deeply pigmented, marked with irregular points and 
lines, the surface of spore minutely and irregularly punctulate, the spherical 
faces showing in addition a coarse and usually regular reticulum, the meshes 
mostly 15 to 20 w wide, inclosed by a system of high and thin ridges similar to 
the wings and usually involving the wings themselves, the plane faces covered 
by similar reticula; reticula sometimes irregular and incomplete, especially on 
the plane faces; elaters pale to dark brown, more or less curved, mostly 150 to 
800 w long and 12 to 14 w wide, tapering slightly toward the blunt ends, some- 
times unispiral or bispiral throughout but usually bispiral in the median por- 
tion for a variable distance and unispiral at the ends. 
On rocks and banks, sometimes on coral formations; apparently restricted to 
the West Indies and especially abundant in Cuba. The following specimens 
have been examined:

tributed in Wright’s Hep. Cub., as #. teneila; a third specimen, distributed in

The following West Indian specimens, cited from the literature, are also of 
interest: 
CuBpa: Banks of the Carima River, 1839, Otto (type of Fimbriaria 
cublanjensis), 
HiIspANIoLaA: Without definite locality, date, or collector’s name (type of F. 
elegans) ; Santo Domingo, Eggers (listed by Stephani, as I’. elegans, in Bull. 
Herb, Boiss. 7: 199. 1899). 
The original material of Fimbriaria eleyans came from the island of His- 
paniola, no further data being supplied. In all probability it was collected by 
the Italian botanist Bertero, who visited the West Indies in 1821, since one of 
his manuscript names is quoted by Sprengel as & synonym. This original ma- 
terial is not represented in any of the herbaria consulted by the writer. In its 
absence it has seemed justifiable to associate the name A. elegans with the 
commonest and most widely distributed of the West Indian species, more es- 
pecially since this agrees in all essential respects with the original diagnosis
