Another curiosity of the Aculama was a large fresh-water prawn, of which I got wind from the natives’ talk. As soon as I heard it mentioned, I told my boys that if they could bring me a specimen I would pay well for it, and also for examples of the fish of the Aculama. They accordingly went in quest of the crustacean, and before long they brought me a specimen. The prawn haunts the eddies under the large boulders, around which the natives draw their net so as to lie close to the shape of the stone. They then pull it out of the water gradually, and occasionally find that they have caught one or two specimens. The variety is about 5 inches long, of a transparent brown when caught, very much like our British prawns, and when cooked of a rich red. The pincers and legs are longer than those of the marine species. They make delightful morsels, and are a welcome addition to the explorer’s larder, which provides changes none too many. In the waters of the Aculama I had also the good fortune to discover an entirely new fish, the _rhiacichthys Novæ Guineæ_, which has been described by Mr. Boulenger, and I am permitted to print his account in the Appendix.
