(no. 954). INDEFATIGABLE IsL.: Academy Bay, on trees, 
375-450 ft., (no. 956); southeast side, rare on trees at 625 
ft. James IsL.: James Bay, on trees at 1300 ft. (no. 955).

ABINGDON IsL.: occasional among rocks in the wooded region 
above 1000 ft. (no. 961). ALBEMARLE IsL.: Cowley Bay, 
occurs first among rocks in shady woodland at 2000 ft. Below 
this elevation the soil is composed entirely of pumice, which 
is not well adapted to support a fern flora; Iguana Cove, 
among rocks in woodland near the shore; Tagus Cove, com- 
mon in lava caverns at 2200 ft. and on the west side of the 
mountain at 4000 ft. (no. 967); Villamil, common among 
rocks 100-3150 ft. (no. 969). CHar Es IsL.: common in 
lava crevices on the inner walls of the main crater at 1400 ft. 
(no. 968). CHatHAm Ist.: Wreck Bay, fairly abundant in 
shady woods at 700 ft. (no. 966). INDEFATIGABLE ISL.: 
Academy Bay, common in vegetable mold among rocks, 350- 
500 ft., (no. 962); northwest side, occasional at 1000 ft.; 
southeast side, common among rocks at 625 ft. JAmeEs IsL.: 
James Bay, common above 1300 ft. (no. 966). This fern is 
most abundant in the lower part of the moist region but 
usually disappears when the vegetation becomes dense. Fur-

James Ist.: James Bay, common in open woodland above 
1500 ft. (no. 969). ‘“‘Large sword ferns’’ were reported from 
the upper regions of Aprncpon IsL., and Banks Bay, ALBE- 
MARLE IsL. by Mr. F. X. Williams, the entomologist of the 
expedition. From his description it seems very likely that it 
was this species that he saw. Further distr. S. U. S., Mex.,
