50 THREE CRUISES OF THE “BLAKE.” 
2 
species in the “ Blake” collection, and half of them were new. 
The largest species is Colossendeis colossea (Fig. 254), in which 
the slender legs are nearly two feet in extent, and the rostrum 
more than an inch long, while the more slender Colossendeis 
macerrima spreads to fourteen inches, and has a rostrum fully 
as long as in the larger species. These species were taken in 
500 to 1,200 fathoms. The new genus Sceorhynchus (Fig. 
255) is remarkable for its spiny body and swollen and reflexed 
rostrum ; the legs of 5. armatus (Fig. 256), the single species 
taken below 1,200 fathoms, are nearly five inches in length. 
The most abundant species of Nymphon is also the largest 
known species of the genus. One of the species of the new 
genus Pallenopsis, dredged from 260 to 330 fathoms, is more 
than twice as large as any of the species from allied genera 
belonging near the shore or in comparatively shallow water. 
There 1s a great contrast between the life of the communities 
of barnacles, such as we find living crowded on our rocks and 
floating on the surface, and that of the comparatively solitary 
deep-sea cirripeds Scalpellum, Verruca, and the like. This is 
readily understood when we remember that the living or dead 
organie matter floating on the surface in the wake of currents, 
and along the shores, supplies the former with 
a large amount of food, while the conditions 
of life at the bottom are far from favorable for 
the species living in deep 
water. 
The abyssal cirripeds 
are usually attached to 
nodules, to dead or living 
shells, to corals, large crus- 
taceans, spines of sea-ur- 
chins, and the like. Scal-

largest species of the genus; it has been dredged by the 
“ Challenger " from nearly 3,000 fathoms, and is quite common 
in the West Indies. Verruca incerta (Fig. 258) also is not an
