belong. In the present instance, however, there could be no 

 doubt whatever. My friend Mr. Charles Hedley, F.L.S., of the 

 Australian Museum, informs me that they much resemble an 

 Aplysia figured by Rang. 



On another occasion, when at Manly, while walking along, I 

 was very much struck with the conduct of an Ant. It saw me at 

 the distance of a few paces. The insect was carrying what I 

 thought to be a green leaf, but what turned out to be a compara- 

 tively large larval ; ' Grasshopper," several times the size of its 

 bearer. The Ant seemed to become very excited, twisting round 

 from side to side, looking at me all the time, and holding its 

 prey up as high as it could. It appeared as if it were challenging 

 me to come on (which I did), and when I tried to effect its cap- 

 ture it dropped its burden, and made several quick springs in my 

 direction, leaping from five to six inches at a time. Whenever I 

 moved to one side my little antagonist followed my motions with 

 its eyes in the same manner as does the Mantis. It looked, 

 indeed, so uncommonly human in its actions that when I captured 

 it I had quite a large amount of respect for it. 



One morning I went to Mosmans Bay (Port Jackson), and 

 walked from thence along the harbour coast. After walking for 

 some distance, I observed two fishermen about to haul in their net ; 

 so I went out with them in their boat, and assisted in the unloading 

 of the net. It was a poor haul (i.e. looking at it from the fisher- 

 men's point of view, but not from the naturalist's), consisting as 

 it did almost solely of small Discophorce and immature pelagic 

 Crabs (Neptunus pelagicus (PL IV.) and N. sanguinolentus, Thala- 

 mita sima, Charybdis cruciatus, and Nectocarcinus integrifrons) . 

 There were a few specimens of Squilla Icevis, also of the handsome 

 Prawn Penesus canaliculatus, and of the smaller and commoner 

 Prawn P. esculentus. There was also a goodly number of species of 

 small fishes, the most noticeable of which were the " Fortescues" 

 (Pentaroge marmorata) , and two specimens of the " Stink Fish" 

 (Callionymus curvicornis). The first mentioned is a harmless- 

 looking little creature, but in reality it is just the reverse. It 

 is armed on each side of the head with exceedingly sharp spines. 

 When the poor unsuspecting mortal picks up one of these care- 

 lessly, it whirls round its head suddenly, and the spines inflict a 

 wound of a very painful nature. I captured several of these, 

 however, without being injured. Whilst thus engaged I noticed
