Ch. YIII.] loss op the dredge. 127 



some specimens dredged by Sir E. Belclier off the coast of 

 Borneo. These specimens measured in some instances 

 2J inches in diameter, and some of them are in the British 

 Museum. It is interesting to observe the spread of this 

 form fully 20° further north, in the N.W. corner of the Pacific 

 — for one of these great Foraminifera, 1^ inch in diameter, 

 I found oif the Raleigh Rock. Its edges were somewhat 

 broken, by being crushed up in the dredge ; but what was 

 very remarkable was that it bore evident marks of having 

 undergone severe fracture in an earlier stage of its existence, 

 which it had patched up, and in process of growth had 

 become quite round and orbicular once more. In Cyclo- 

 clypeus there is a great advance upon the simple structure 

 of Orbitolites, though in outward appearance they closely 

 resemble one another ; but the cells which enter into the 

 construction of Cycloclypeus, instead of being closely con- 

 nected with one another, are singularly isolated, while the 

 shelly covering is wonderfully elaborate, as may be seen by 

 referring to Dr. Carpenter's figures in the Philosophical 

 Transactions (1856). 



Notwithstanding that I had already more material than I 

 could possibly manage, I was anxious to accumulate more 

 riches, and hoped to make more discoveries, and the dredge 

 was again dropped overboard, while the examination of the 

 first mass was continued. At length it was drawn up, and 

 full of expectation I looked over the side, but alas ! the 

 handle alone came to the surface, with one scraping side 

 still attached, but bent nearly double. It had caught 

 against a rock, and unfortunately not being a dredge of the 

 self-disengaging kind, a lurch of the ship had torn it in 

 halves, and left frame, net, and contents at the bottom of the 

 sea. I had no other dredge at hand, and it was impossible to
