line. This is also the case with Leptochilus, and on the 

 same grounds that Hymenolepis differs from PJtymatodes, 

 does Leptochilus differ from Colysis, with which it agrees in 

 habit.

Surculum short, caespitose. Fronds contiguous, furcately- 

 pinnatifid, to 12 inches long, coriaceous, sparsely squami- 

 ferous, segments lanceolate-cuspidate, the fertile slightly 

 contracted. Veins obscure, simple or forked, free, or their 

 apices arcuately anastomosing, forming linear transverse 

 superficial receptacles, which by contiguity constitute a con- 

 tinuous or interrupted, linear, intramarginal, naked sorus.

OBS. In 1851 Fee separated the species of this genus 

 from Tcenitis, and constituted of them the genus Cuspidaria ; 

 but as that name had been previously occupied by both 

 Link and De Candolle for two plants of different orders, 

 I therefore in the " Botany of the Voyage of the Herald " 

 substituted the above name. Fee enumerates three species, 

 two of which I adopt ; the third having fasciculate adherent 

 vernation comes under the genus Pteropsis. In habit and 

 texture of the fronds, the species of this genus, seem to 

 mark their relationship to be with Fleopdtidece, but differ 

 in the venules anastomosing, forming arches near the 

 margin, on which the sporangia are produced.
