worms (see notes). A pretty little crab, of a sky-blue color 
( Mycteris longicarpus) lives in crowds on these shores at about 
half-tide mark, in holes—it corresponds to our fiddler or soldier 
crab / Gelasimus vocans). After a pleasant sail back to the hotel 
we returned in our carriage to the city of Sydney, where I was 
happy to hear that the British Surveying Ship ‘“Herald” had 
arrived from New Caledonia, during our absence. 
2nd. The average temperature of the air, during the day, in 
this part, is 75°, that of the water 70°. The wind usually from 
the northward. 
3rd. To-day I went to the city, after attending to some business 
matters, took a walk about the town. 
4th. This day I dredged, in company with Mr. Wright, in a 
little cove near the entrance of the harbor, where among the soft 
sponges of the bottom, I found a rich harvest, curious shrimps, 
naked mollusks, etc., and a beautiful planaria of the genus 
Eolidiceros. 
Sth. Through the kindness of our Commander in offering me 
the use of his boat, I visited the “Herald.” Her naturalist, Mr. 
MacGillivray, was not on board, but I was very kindly received 
by the two medical gentlemen connected with the vessel, who 
were both men of science. One of them! showed me a book con- 
taining a number of sketches, beautifully drawn, of some elaborate 
anatomical investigations on the lower animals, which he had made 
on board ship, having the benefit of a large room with plenty of 
light. I was shown several interesting specimens collected at New 
Caledonia and the neighboring islands, among which were several 
new land shells, and some well preserved specimens of the animal of - 
Nautilus pompilius, which, it seems, is used as food by the natives 
of those islands. There were also many interesting minute shells 
of the new order Crucibranchiata, species of which they had taken 
abundantly in these seas. They used but little alcohol in their 
_ preservation of fishes, etc., almost all their specimens being dried. —
