NARRATIVE OF THE CRUISE.

“ The large number of the Terebellidse is noteworthy. Amongst the new genera are 
Eupista, in which the branchial processes are simple, and Eutlielepus, in which the three 
post-cephalic segments have a process or lobe jutting forward from the anterior border on 
each side, and a long simple branchial filament. This family, like that of the Serpulidse, 
reaches very profound depths (such as 3125 fathoms), and both range to shallow water. 
“The tubes fashioned by many forms are peculiar. Thus the tube of a large Eiyali- 
ncecia is as wide as a goose-quill, which it much resembles in texture, but it is nine or ten 
inches in length. Nothrice from the deep sea have their tubes strengthened by long 
glassy spicules of sponges, by long arenaceous Foraminifera, by tubes of Serpulce, and in 
the case of a Japanese form, by the long linear leaves of the Coniferse carried to the 
sea by rivers. Perhaps the most remarkable tube of the group, however, is that of 
Notliria willemoesii, n. sp. It is a large, rounded, and firm tube, externally composed of 
of greyish sandy mud, and internally of a tough whitish secretion. The greater part 
of the surface is furnished with a series of long, slightly bent elastic spines composed 
(after the manner of a sponge spicule) of layer upon layer of a hyaline secretion, probably 
of the same nature as the inner wall of the tube. The great length (500 mm.), again, 
of the tubes of Notliria elder si, n. sp., is noteworthy. The new abyssal forms of the 
Ampharetidse inhabit tubes of mud lined by a chitinous layer. The tubes of Pista 
mirabilis, n. sp., one of the Terebellidse, are firm, rounded, chitinous structures tapering 
from the anterior to the posterior extremity and studded all over with long spinous 
processes, the wall of the tube being minutely marked by fine — almost linear — transverse 
wrinkles. The tube is apparently free, in the majority, but in others it is immersed in 
sponges.” 
Hong Kong. 
The colony of Hong Kong consists of the island of that name and -the opposite penin- 
sula of Kowloon. The island is about 9 miles long, N.W. by W. and S.E. by E., and 
from 2 to 5^ miles broad ; its shores are much indented, particularly on the south side. 
The Kowloon Peninsula, on the main coast of China, opposite Hong Kong, is 2 miles in 
length and 1 in breadth. The total area of the colony does not much exceed 30 square 
miles. The island was originally ceded to Great Britain in 1841, and the peninsula of 
Kowloon in 1861. 
The harbour of Hong Kong is formed by the strait separating the island from the 
China coast ; it is almost completely landlocked, and possesses anchorage ground 
extending over nearly 10 square miles. 
The general aspect of Hong Kong, and of the neighbouring part of China, is very 
fine, for the island consists for the most part of rocky ranges, culminating in Mount 
Victoria, 1825 feet above the level of the sea, and the hills on the China coast are similar
