LTNNEAK SOCIBTY OF LONDON. I 5 



Mr. J. R. Willis Bund exhibited specimens in spirit of the 

 Eainbow Trout {Salmo irridens), which bad been reared at the 

 Hatcheries of the Fisb-Cultiire Establishment at Delaford Park. 

 He pointed out the great difference in size of members of the 

 brood which were of the same age, and reared from the same 

 batch. He mentioned that circumstances tended to show that 

 it was a migratory fish ; hence, as such, the value of its in- 

 troduction into this country as a stream Trout would materially 

 be diminished. 



Photographs were exhibited and a letter read from Mr. J. Gr. 

 Otto Tepper, P.L.S., retrarding a Gall-formation on SccBVola 

 spinescens, E. Br. (Benth. Flora Austral, iv. p. 87), observed by 

 him in South Australia. The following is an extract from Mr. 

 Tepper's letter: — "Tiie shrub in question is very densely branched, 

 but not usually more than from 1| to 3 feet high, in the neigh- 

 bourhood of Ardrossan, York Peninsula. It occurs either solitarily 

 among other shrubs on Tertiary ground of a poor clay intermixed 

 and resting upon fossiliferous siliceous grits, or in small groups 

 in shallow grassy depressions. As sheep were depasturing on 

 the latter locality, the white fluffy lumps, promiscuously scattei-ed 

 among the spiny branches, were j^assed frequently unheeded under 

 the supposition that they were locks of wool torn by the spiny 

 branches from the passing sheep. The Grail is often seen on 

 other shrubs, such as Bursaria spinosa &c. One day, being in 

 want of some wool for a plug, I discovered that the supposed 

 locks were really galls, each containing a single inhabitant, pro- 

 bably a member of the Coceidae. Of these there are a consider- 

 able number of indigenous sjiecies, some producing very extra- 

 ordinary forms of galls, often exhibiting some parts much 

 exaggerated which are normally minute. In the present instance 

 the hairs of the flower-buds were affected; while in other kinds 

 of galls, very common on Oasuarina quadrivalvis, the minute leaf- 

 scales appeared, enlarged, at the same time that the internodes 

 between the whorls were almost entirely suppressed. 1 forward 

 two copies of a photograph of galls, kindly taken by Praser S. 

 Crawford, Esq., Government Photo-lithographer ; the specimens 

 themselves will be forwarded as soon as possible for examination 

 by some of the Linuean Society's specialists." 



On behalf of Mr. W. Brockbank, P.L.S., Mr. J. G. Baker 



exhibited photographs of a series of forms of Narcissus refiexus 

 of Brotero, from Ancora, N. Portugal, and grown in his garden 

 at Didsbury. N. rejiexus is ranked as a species by Nymnn ; but 

 in the Portuguese plant the variation in the size and shape of the 

 corona is so great, that it is evident that no definite line of de- 

 marcation can be drawn between the Spanish N. triandrus and 

 the Brittany N. calnthinus ; and therefore that all the varietal 

 forms of the section Oanymedes constitute a single species.
