weight than the average (3 to 5 lbs.) which they mention. Dr. Comrie, however, writes that S. paucidens runs from 5 to 6 lbs. and has a maximum weight of 10 lbs. The teeth of this, the “weak-toothed” salmon, were not easily found by me in the vomer and palatines of above specimen, possibly on account of the “curing” of the fish. Possibly also the arched back may be due to packing into small barrels. As they appear in the Dunedin market, these fish are all as nearly as possible of the same weight, 6 to 7 lbs.; whether this is accidental or not, I have not means at present of determining. As food they are excellent. This fish, as well as the S. quinnat, among other things differs remarkably from the S. salar of British rivers in the size and shape of the sub-operculum, which is very large relatively to the operculum and has a rounded margin which, with the two joints, forms a figure approaching a sector of a circle. This S. paucidens likewise has no spots anywhere, and the same may be said of several other specimens I have looked at of the same fish. The tail also is very large and forked. The S. trutta from the Clyde, and which may now be seen in the Otago Museum, I have compared with Dr. Günther's description of four specimens from the river Tweed, varying in length from 18½ inches to 35 inches. The relative length of the head to the body and the depth relatively to length of body, without the caudal, agreed very well; but all the fins of the Clyde fish are larger than those of the Tweed sea-trout. The fin-rays of the Clyde specimen are fewer by one or two—in the dorsal, pectoral, and anal fins—than those given by Dr. Günther; the ventral being the same in the number of rays. But they agree almost exactly with those given by Yarrell. The gill-covers in form and the colours of the body fins agree with the descriptions of those by Günther and Yarrell. The difference in the number of fin-rays from those given by Günther is apparent rather than actual, as the latter seems to have included the rudimentary or sub-rays, which I have omitted. The vomerine teeth differ also in being nearly all present in this Clyde specimen, while in the Tweed specimens of Dr. Günther they are only present in small numbers on head of vomer. The fish, which undoubtedly is a sea-trout, is evidently not a mature fish or rather not come to its full growth. Its general appearance suggests this in the want of fullness of body, while the size of the tail and head and presence of so many vomerine teeth confirm the supposition. The sea-trout from Sawyer's Bay agrees in most of its markings with the Clyde one described above, also with Günther's and Yarrell's fish. It is also identical with the stuffed S. trutta in the Otago museum, taken at Otago Heads in 1874. That is to say, it has the correct and liberal coating of bright silvery scales, the gill-covers are silvery, the back and all the fins
