ture soundings were taken to 800 fathoms; during the opera- 
tion, however, we met with rather a serious loss, for the sound- 
ing-line with seven thermometers attached fouled the propeller 
and was carried away. On the 27th, the depth was again 2650 
fathoms, with a bottom of grayish red clay. The trawl was put 
over in the forenoon, and as this was by far the greatest depth 
at which we had attempted to employ it, we looked with great 
interest to the result. In the evening the trawl returned to us 
in safety, and contained a caridid shrimp, a number of worm- 
tubes composed chiefly of small foraminifera, two examples of 
an irregular sea-urchin, and a number of ophiurideans referred 
to the genera Amphiura and Ophioglypha. The crustacean 
may be a pelagic form living at intermediate depths, for such 
we have reason to believe exist and attain a large size; the an- 
nelid we had not an opportunity of determining, as the tubes 
only were present; the urchin is a species new to science and 
of great interest. Calymne relicta (Fig. 102) is at first sight ex- 
tremely like the normal Anancuytmp™; indeed, it has a close 
general resemblance to the common chalk form Ananchytes 
ovata. Many important characters, however, separate it from 
the genus Ananchytes, and until we have had an opportunity 
of comparing the whole series, I am not prepared to say that 
this genus may not find its place in a family as yet undefined, 
with Pourtalesia, Aceste, and Aérope, and some wonderful new
