ANDREWS — ON SALMONID.E. 53 



this new form proves for the genus Penium), and to certain species of 

 Closterium on the other. 



It affords me great pleasure indeed to avail myself of the opportunity 

 to name so distinct a species after David Moore, Ph. D., F. L. S., 

 M. E. I. A., &c, of the Glasnevin Botanic Garden, not only as a token, 

 inadequate though it he, of respect for that gentleman's high scientific 

 attainments and personal qualities, hut also as commemorative of a 

 very agreeahle little excursion, when we had each the pleasure to he of 

 the party, on which occasion I first gathered Penium Mooreanum. 



The following paper was then read : — 



Remarks on the Salmonidje. By William Andrews, M. R. I. A., 

 President. 



So much has heen discussed on the subject of the Salmon, that anything 

 now advanced will only he considered as tiresome reiteration. But with 

 all this, so little has really heen maintained of the broad principle that 

 would promote so important a branch of resource, the chief advocacies 

 being the interests individually of tidal or of riparian, that unless go- 

 vernment legislation, with proper consideration, and with well digested 

 local information, should interpose, the last state of those fisheries 

 will be worse than the first, and more clamours of dissatisfaction will 

 arise. 



The views that I had intended to submit to you this evening were 

 to exhibit a series of specimens of the growth of the several species of 

 the Salmonidse, and to show how those growths and peculiar charac- 

 teristics were affected by position or by connexion with lakes or with 

 alpine streams of those rivers that they frequented, as well as in rela- 

 tion to the geological features of the country through which the rivers 

 have their course. These causes tended greatly to give variance to 

 stages of growth, and to proportion and weight, and to have important 

 effects on the earlier and later periods of spawning. Not having had the 

 opportunity of making the excursion I had contemplated, I must defer 

 that paper to another meeting, and also some points of anatomical 

 and physiological interest bearing upon the subject. The question has 

 been frequently put to me, " Has it been determined are all the Salmon 

 that frequent the rivers around the coast of Ireland the one species?" 

 Hence may present the reasons of distribution, the difference of form, of 

 superior growth, of variableness of seasons of spawning, and of visiting 

 and ascending rivers, that so materially occur — all those points the com- 

 ments on the foregoing observations would have embraced. 



Until the opportunity could be accomplished, I thought it might be of 

 interest to submit some remarks on the character that the male Salmon 

 presents after its periodical season of spawning had been over, and pre- 

 vious to its being able to effect its retreat to the sea. The accurate 

 drawings exhibited, taken from the recent specimen, arc from the pencil
