770 MR. E. E. AUSTEN ON A RECENT ZOOLOGICAL [June 16, 
the time occupied by the cable-operations, with the exception of 
Santarem, where we remained for four days and a half. We lett 
Manaos on the downward voyage on Feb. 15th, preceded two days 
earlier by Mr. Pickard Cambridge, who had decided to return to 
Santarem in order to stay for a fortnight in the forest some nine 
miles inland from that town, at a cottage which had been most 
kindly placed at our disposal by Mr. Wallace, an American trader. 
After due consideration I had decided to remain with the ship, in 
order to visit other localities near the mouth of the river, and so 
make the most of our opportunities by dividing our forces. On 
the downward voyage we ran aground in mid-stream near Monte 
Alegre, and remained there for four days before getting off. Un- 
fortunatefy I was suffering at the time from a swollen foot, and 
being scarcely able to walk I was unable to profit by this delay. 
After another day’s collecting at Gurupa, we reached Macapa on 
the northern shore on Feb. 24, and I was enabled to collect for a 
day at a locality which, so far as I am aware, had not been visited 
before by a European naturalist. Thence, after calling at Chaves, 
in the island of Marajo,and again at Breves, we returned to some- 
where near our old anchorage in the Pard River on March dth, and 
the expedition was nearly at an end. Connections, however, still 
had to be made with a few places in the vicinity of Para, and, as it 
was expected that these operations would take at least a fortnight, 
T resolved to avail myself of an opportunity which occurred on the 
following day of going to stay for a time at Mosqueiro, a little 
place seventeen miles below Para on the same shore, in order to 
make the utmost of the time that still remained for collecting. I 
remained here until March 16th, when the ‘ Faraday’ arrived, and 
T returned in her to our anchorage below Pard. During the second 
half of my stay at Mosqueiro work was much interfered with by rain. 
Mr. Pickard-Cambridge, who had already returned from Santarem, 
now rejoined the ship, and the next few days were occupied mainly 
in preparations for the homeward voyage. We sailed from Para 
at 6 A.M on March 24th, and reached Gravesend on the morning 
of April 14th. 
On referring to my diary I find that, although we spent rather 
more than eleven weeks (79 days) on the Amazon and the Para 
River, owing to the special conditions of the expedition, the 
actual number of days on which I was able to collect ashore 
amounted in the aggregate to only five weeks (55 days). Then, 
again, in considering results, it must be remembered that in our 
flying visits to the various localities already mentioned between 
Pard and Manaos we were often hampered by much uncertainty 
as to the exact time for which the ship would remain, and by the 
necessity for returning to the shore at a particular moment in 
order to catch the launch or boat going off to the ship. On the 
other hand, the days spent in steaming from place to place, and 
others on which we were unable to land, were by no means wasted, 
since the numbers of insects which were attracted by the ship’s 
electric lights at night kept me pretty busily occupied.
