paratively stout, broad for its length, scarcely tapering, evenly 
curved (‘‘ boomerang”-shaped), ends broadly rounded; contents 
dense, consisting of scattered rounded granules. Perhaps the most 
curious point in the present instance was that, mounted only some 
forty-eight hours in acetate of potash, the green contents had to all 
appearance become dissolved, and only the empty hyaline otherwise 
unaltered cell-walls were now to be seen of some half dozen ex- 
amples that were on the slide.

Quasi-Fungal Growth in Shell of Limax.—Prof. Mackintosh 
ealled attention to an apparently fungal growth in a shell of Zimax 
cinereus, mounted last December. He had noticed the growth a 
couple of days after mounting; and it had continued in the same state 
since. It might be in the medium (alcoholic glycerine); but it 
seemed to him to be in the periostracum. If this were so, it would 
be similar to, but less easily accounted for than, the supposed 
hyphal growths in the shells of branchiate Gasteropods. 
Spicules of new Species of Aleyonaria from ‘ Challenger’ Collec- 
tion.—Dr. EK. Perceval Wright exhibited some mounted spicules of 
two new species of Alcyonaria belonging to the genus Primnoella, as 
well as drawings of the polyp-colony. These formed part of the 
collection made by the ‘Challenger’ expedition, of which full de- 
scriptions are to appear in the forthcoming Report. 
Cystidia from Gill of Gomphidius glutinosus.—Mr. Greenwood 
Pim exhibited a section of the gill of Gomphidius glutinosus, which 
showed the so-called cystidia developed to an extent very unusual 
amongst the Agaricini. These bodies, which in Agarics in general, 
except the Coprinaril, are scarcely discernible, are looked upon by 
Mr. W.G. Smith as being the male organ in this group. In the 
specimen shown there was nothing to confirm this view, the organ 
consisting of large cells resembling hairs, filled with a granular 
protoplasm and projecting a long way from the hymenial surface. 
It is probable that these somewhat anomalous bodies are analogous 
to the paraphyses met with in the Pezizas. Nothing resembling 
the antheridia described by Mr. Smith was discernible in Mr. 
Pim’s specimen, in which the basidiospores were abundant and well 
developed. 
Motile state of the “ 80” Organism (Club Minutes, January 1871). 
—Mr. Archer showed the production he had before drawn atten- 
tion to under the provisional designation of the ‘* 80” organism ; 
and he would first say that quite as little as then was he able to 
arrive at a conclusion as to the nature or affinity of this puzzling 
and by no means attractive-looking organism. But he drew atten- 
tion to it again in order to exhibit once more its puzzling and 
astonishing motile condition—-that is to say, to show the broken-up
