directs it to be substituted for Prionopteris . In the course of this 

 examination, Mr, Moore further determined Spheeropteris Hookeriana, 

 Wall. Cat. No. 775, in corrig. p. 248, to be the same with Diacaipe 

 aspidioides, Blume ; a genus distinguished from Spharopteris by its 

 sessile, not stipitate, sori, and which Mr. Moore refers to a section 

 (Woodsiece) of Polypodiete, which connects that group with the Cya- 

 thecB. Dr. Wallich compares it with Davallia stipellata. Wall. Cat. 

 No. 260, which it resembles in general appearance, but the fructi- 

 fication is altogether different. Davallia stipellata was identified 

 with Acrophorus tiodosus, Presl, and doubtfully with Monachosorum 

 davallioides, Kunze. This genus the author referred rather to Aspi- 

 diece than Davalliece, placing it with Cystopteris in a subsection of the 

 former, which forms a connecting link with the latter through the 

 genus Microlcpia. In the view here proposed it would include most, 

 if not all, of the species which have been referred to Leucostegia, as 

 well as a fern described by Sir W. Hooker under the name oi Davallia 

 Jamaicensis. The species of the genus Acrophorus would conse- 

 quently stand as follows : — 



1. Acr. nodosus, Presl = Aspidium nodosum, Blmne; Davallia sti- 

 pellata, Wall. ; Davallia nodosa. Hook. ; Monachosorum davallioides, 

 Kunze ? 



2. Acr. immersus = Davallia immersa. Wall. ; Leucostegia im- 

 mersa, Presl. 



3. Acr. chcErophyllus = Davallia chseroph3dla, Wall. ; D. ligulata, 

 Wall. ; D. pulchra, Do7i, fide not. MS. in Herb. Soc. Linn. ; Leu- 

 costegia chaerophylla, L. ligulata, and L. pulchra, /. Smith. 



4. Acr. affinis = Leucostegia afiinis, J. Smith ; Davallia affinis. 

 Hook. 



5. Acr. hispidus = Davallia hispida, Heward; D. Novse-Zelandiae, 

 Colenso. 



6. Acr. memhranulosus = Davallia raembranulosa, Wall. 



7. Acr. parvulus = Davallia parvula. Wall. ; Leucostegia parvula, 

 J. Smith. 



8. Acr. Jamaicensis = Davallia Jamaicensis, Hook.
