Spiders from the Bahama Islands. 329 
G. pallida, McCook, Amer. Spid. iii. p. 209, pl. xiv. fig, 8.—California. 
G. preciosa, McCook, Amer. Spid, ii. p. 211, pl. xiv. fig. 7.—California. 
The species pallida and preciosa are in all probability 
identical, and may be eventually regarded as subspecies 
of Linneus’s species from St. Thomas. I have no doubt, 
however, that guadridens, C. K., is identical with tetracantha. 
Two other forms—one from St. Vincent, with carapace, legs, 
sternum, and ventral area entirely black; the other from 
Beguia, Canonan and Union Islands, with carapace and legs 
bright orange-red, sternum and ventral area black, the latter 
spotted with yellow—may be added to the varieties of this 
species. ‘The form with the red carapace is obviously the 
typical one, though I have no material from the Island of 
St. Thomas, for Linneus’s description runs :—‘‘ Cap. rufum, 
pedes sanguinei.”’ 
The species as recognized above has been recorded from 
the Antilles, St. Thomas; St. Vincent (Simon) ; Beguia ; 
Canonan and Union Islands; California, Mohave Desert 
(Mare).

United States, 
The type of A. canerdformis, Linn., is the figure in Sloane’s 
‘Jamaica,’ il. p. 197, t. 235. fig. 4. Linneus also quotes 
Browne, Hist. Jamaica, p. 419, t. xliv. fig. 5. (These figures 
have been reproduced in our Pl. VII. figs. 9 & 8.) 
The type of A. hevacantha, Fabr., is the figure in Browne’s 
Hist. Jamaica, t. xliv. fig. 5. Fabricius does not mention 
“Dom. Banks” in either of the places where he quotes and 
describes Ar. hexacantha; and although there is a specimen 
labelled with this name as “ type” in Coll. Banks Brit. Mus., 
it cannot be accepted as the type of Fabricius’s species.
