284 DREDGING REPORT, 1862. 
been taken on our coast. Besides this there are in the list two 
interesting additions to our local fauna; viz., Uraster rosea, a 
species hitherto unrecorded on the east coast of England; and 
Thyondium commune. 
The sandy banks lying immediately within the Dogger seem a » 
very favourable locality for the orders Ophiuroidea, Asteroidea, 
and Echinoidea, which were there met with in greater numbers 
and variety than elsewhere. 
OPHIURA TEXTURATA, Lamarck. 
This species was dredged in considerable numbers during the 
first trip on sandy ground off the Dogger Bank. Many of the 
specimens were of large size, and some exhibited very plainly 
the curious mode of reproduction of broken limbs, which char- 
acterizes the tribe. 
OpHiuRA ALBIDA, Forbes. 
Several specimens, mostly of rather small dimensions were 
dredged on a sandy bottom off the Dogger, and in Berwick 
Bay. 
OPHIURA NoRMANI, Hodge. 
Several specimens of this hitherto undescribed form were ob- 
tained off the Dogger Bank. Mr. Hodge’s description of the 
species will be found at a subsequent page. 
OpuHiocoma FILIFoRMIS, MJiiller. 
Taken in considerable numbers on a fine sandy or muddy 
bottom near the Dogger Bank. One or two were also seen 
during the second trip, but the excessively fragile character of 
the creature rendered its preservation in perfect condition almost 
impracticable. 
OpHrocoMA BELLIS, Link. 
‘Two specimens taken off the Dogger. It is rather surprising 
that this very beautiful species was not met with in more abun- 
dance, especially during the second expedition. It is by no 
means of unfrequent occurrence off the Durham coast.
