lis VOYAGE FROM INDIA TO SIAM AND MALACCA. 



22. — Last nig-ht we had a very strong thunderstorm, and as 

 we passed the islands on the Western side, and lay below the 

 high Cambodian mountains, which are also situated on islands, 

 the echo was tremendous. The lig'hting descended perpendi- 

 cularly, sometimes in double flashes on the mountains. It was 

 white and at times blue. Just opposite our ship and further 

 north-west, there was another storm cloud which sent forth fewer 

 flashes of lightning, which were rose-coloured. 



I dried some specimens of the new kind of mollusc, which 

 for now I will call Clio ; which they were being dried in the sun 

 their blue gut changed into a beautiful red. I also put some in 

 spirits, also the small ones hanging together, which I will call 

 Clio concatenata at present. 



At midday many cat fish were caught, Siluris Cattus. I 

 made the following description of one which was almost a foot 

 and a half long: The head is flattened and the upper part of the 

 mouth rather projecting and pointed towards the end, flat at the 

 lower side ; the lower part of the mouth is large and rounded. At 

 the angles the upper part of the mouth has on both sides a beard, 

 looking like a single thread, which is as long as the head is wide 

 in this place. The lower jaw has four such threads in one row, 

 the mouth is large and has many very short teeth. Above the 

 upper lip there are two round big nostrils on each side, which are 

 quite uncovered. 



23 — Early this morning, as the weather was fine, the ship 

 was surrounded by many thousands of Cliones concatenatce, some 

 of them being one and a half feet long. To-day I caught again 

 some of the big Cliones without sheath and found them full of 

 little Onisci ( Crustaceans ), which animal I described as follows: 



The animal is oblong, pointed at both ends, about three lines 

 in length and hardly one in width. The head is covered by a skin, 

 which projects straight out and is pointed towards the end having 

 the shape of a shield ; the edges are sharp and concave below. 

 The mouth is slightly projecting below, and is surrounded by 

 S3me bristles. The antennae are placed below the mouth 

 at the sides and look like hair ; the feet are pressed to the 

 body, they are round at the end and club-shaped, have one joint 

 in the middle and two at the base, they are formed of a horny 

 stiff substance, and are g'enerally as long' as the body. Tlie eyes 

 are placed at the side of the head, they are long, big, and green.
