 By Robert E. Snodgrass. 



SICAROIDES ULTRIFORMIS. 



Rare; secured at only one place in the archipelago, viz., under 

 rocks on flat area at top of cliffs west of Gardner Bay, Hood Island. 

 The soil at this place and the unweathered under sides of the surface 

 rocks are of a bright brick-red color. All the individuals of this 

 spider seen were also of this same color. They were, accordingly, 

 inconspicuous so long as they remained quiet. Several other nor- 

 mally colored species occurred at the same place. 



The eggs are inclosed in a cup-shaped case, having a flat top with a 

 projecting rim (Plate iii, fig. 9). A nest secured is composed of 

 fine particles of earth held together in a delicate network of threads 

 (Plate III, fig. 10), having, consequently, the same color as the rock 

 to which it was attached, and, were it not for its extraordinary shape, 

 would appear to be a part of it. The nest was taken in April. In 

 September numerous young spiders had emerged through a transverse 

 slit-like opening near the top, extending so far around that the top was 

 almost separated from the rest like a lid. 



LOXOSCELES LONGIPALPIS. 

 All the Hood Island specimens were taken at the same locality as 

 the last species. They occurred in the crevices of rocks lying on the 

 surface. Some were without webs, others had an irregular one spun 

 about them in the recesses of the rock. 



CORYSSOCNEMIS CONICA. 

 Found only on Hood Island, under rocks at top of cliffs west of 

 Gardner Bay, along with last two species. Spins an irregular web 

 on the under surfaces of rocks. Exceedingly swift in its movements. 

 On disturbing one it first darted out of its web, then as quickly 

 back again, and, clinging to the center, vibrated it so rapidly as to be 

 almost invisible. 



AYSHA PACIFICA. 



Rare in the archipelago. The Albemarle specimens were both 

 taken in the Turtle Point mangrove swamp. One was secured in a 

 net by beating the leaves of the trees, the other was taken with its
