"Sir,--Although in the course of my life, I have had little opportunity to pay attention to the study of Ichthyology, it occurred to me, as now and then a leisure moment was afforded from official duties, that it would perhaps be useful, as well as amusing, to collect and make drawings of the fish about King George's Sound; and I have been in a great degree stimulated to do so, from an accidental visit of my friend, His Excellency Captain Grey, Governor of South Australia, who advised me to forward the drawings to you for the purpose of being placed with others of a similar kind in the British Museum, where ultimately sufficient material may be collected to give some account of the New Holland fish. "Nothing is assumed as to the execution of the drawings; in fact it often occurred when I set off in my little skiff, (especially in the outset) that seven or eight species were procured in the course of the excursion, which compelled me to make drawings of all when I came home tired in the evening; forwarding them to ensure, as far as possible, their colours before they became extinct--a sort of forced effort in respect to the execution has, therefore, only been effected. The outline of nearly every specimen was taken from ACTUAL PROFILE, by laying the fish upon the paper--in this way I defied error in outline--of course, afterwards carefully drawing and correcting various parts which required it, in a free or rough manner, time not admitting of much pains. "In naming the fish, I have merely attempted to give the aboriginal and popular names known to the sealers and settlers. In obtaining the former, no little difficulty has been experienced. The younger natives generally giving different names to those of the elder; but finding the fish named by the latter more descriptive, I have, of course, in most instances, adopted them. "For instance, No. 1, KOJETUCK means the fish with the bones; which is very descriptive, from Koje the bones, [Note 28: This was noticed by Governor Grey.] having very singular bones placed vertically in the neck, connecting the dorsal spines to the back, resembling small tobacco pipes.
