The first rib is a very stout, strongly eurved, compressed bone, thirteen 
inches in length from tip to tip, while the fifth, which is longest, is twenty- 
six inches. Only the first seven have a double articulation with the vertebral 
column. 
The sternum consists of three segments, and shows four articulations, 
its total length being sixteen inches, 
The hyoid is a erescentie bone twelve inches in length. 
The pelvic bones are prismatic styliform bones, nine inches in length. 
The scapular is triangular and strongly ridged, the posterior edge form- 
ing an angle of 85? to the plane of the articulation. Acromion thin, ex- 
panded, and incurved; corocoid thicker; both three inches long, or one-fifth 
the length of the superior edge. 
Humerus and arm bones firmly united. Manus long and pointed, the

Art. LXVII.—Fish and their Seasons. By P. Tomson. 
[Read before the Otago Institute, August 1st, 1876.] 
Tux following table had its origin in a conversational discussion which took 
place at one of the meetings of the Institute during last session. It was 
mentioned, among other things, that there was a good deal of doubt about 
the times when the ordinary food fishes were actually in season, and a few 
particulars as to the length of time they were to be caught might be useful. 
In the hope that the following may go some way towards supplying what 
was wanted, I venture to bring it before the members of the Institute. I 
may state that the mode adopted in gathering the information was by 
noting down the various sorts of fish exposed for sale in the windows ofthe 
fishmongers' shops, as well as by occasional enquiries elsewhere. The work 
was begun on the 1st August, 1875, and was continued daily till the 81st 
July of the present year. During a short absence from Dunedin the notes 
were taken by a friend, who adopted the same method.
