sented a large head, which sprang from the inner side of the olecranon 

 process ; and, as not infrequently occurs among the Simiadas, the supi- 

 nator brevis had no. humeral attachment. 



In Cebus capucinus, Inuus sylvanus, and Macacus sinicus, and ne- 

 mestrinus there was no extensor primi internodii pollicis present, and the 

 extensor ossis metacarpi pollicis was attached to the trapezium. 



The musculus scansorius (Traill) was indistinctly separable from 

 glutaeus minimus in any of these individuals. 



By studying myology systematically in the light of class, of gene- 

 ric or specific, or individual variations of the archetypal arrange- 

 ment, it gives an additional interest to the work of recording accidental 

 non- typical anomalies in man or other animals; as by the examination 

 of these we can sometimes trace the general or partial position and course 

 of the parts in the primal type, and thus we may receive hints as to 

 the zoological affinities of the animals in which the muscles so varying 

 occur. 



Mr. Andrews, Y. P., said, as there had been but one paper on the 

 list for this evening, he thought it might be of interest to make some 

 slight reference to a few species of fish which were captured in the 

 trawl net, especially as much controversy had been perpetually agitated 

 on the subject of that destructive mode of fishing. 



He (Mr. Andrews) had always been the advocate of the trawl system 

 of fishing, as being a mode the most certain of providing the markets 

 with the best and the most valuable edible fish ; and, at the same time, 

 from the superior class of boat that was employed, was the most useful 

 means of forming a body of good seamen and pilots. There were, how- 

 ever, some points of difference between the opinions that he had formed 

 with regard to trawling and those of some who were either for its full en- 

 couragement without restriction, and of others that were disposed to cur- 

 tail altogether the operation of the trawlers. In the use of shore nets, 

 and in the working of the trawl boats in shoal water, it has been stated 

 that no possible injury could result to the spawn or to the fry of fish, 

 particularly if the law directed that the mesh should be of such size, 

 both of seine and trawl net (from knot to knot), that the undersized of 

 all kinds of fish that frequented shoal soundings could escape. Those 

 who urged the complete removal of the working of all trawl boats out- 

 side of headlands deposed that an immensity of the spawn or ova of the 

 fish were destroyed, and that, consequently, the fisheries each year were 

 declining. 



Neither of those views did he (Mr. Andrews) consider to be correct. 

 Prom practical experience of some years he had invariably found, in 

 the working both of the seine and the trawl net, that the size of the 

 mesh was but of little importance ; for in the strain upon the hauling of 

 the one, and of the tension of the drifting of the other, the meshes 

 became so elongated that the smallest- sized fish were retained in the 

 nets. The destruction of spawn could not possibly be effected by the 

 trawl boat ; for the instinct of fish — such as the several species of the
