THE VOYAGE OF H.M.S. CHALLENGER. 
cuticle invests the body with a gelatiniform coating, but the contingencies connected with 
its capture may have altered it, though numerous granules and elongated glands are still 
evident. 
“ The mouth leads into a dark brownish thick- walled pharynx, which in the prepara- 
tion is somewhat moniliform. The latter terminates in a firm white and nearly cylindrical 
region, somewhat narrowed posteriorly where it merges into a longitudinally furrowed 
glandular part (stomach) continuous with the intestinal canal. The nervous system is 
evident on the ventral surface as a double cord, two ganglia being placed antero- 
posteriorly in each segment, the larger in front and the smaller behind.

“ Many interesting deep-sea forms occur in the family Maldanidse, which with the 
closely allied Ammocharkke appear to abound in the abysses. Amongst the Ampharetidse 
the Atlantic and Antarctic Oceans produced some curious new types, such as Rliynchos- 
caphia antarctica, n. gen. and’ sp., from Station 151, a form in which the snout is 
flattened and broadly spathulate as well as devoid of tentacles. Traces of four branchial 
processes are present and there are fifteen pairs of bristle-bundles. 
“Two or three new genera come from great depths, ranging from 1100 to 2300 
fathoms.
