W.C. M‘Intosh, M.D., F.R.S., Corresponding Member. By its 
possession of pre-oral and post-oral bands of cilia, an aquiferous 
system, and other features, this animal shows affinities with the 
Echinodermata; but the form of the adult, the presence of a 
fleshy proboscis, and various other anatomical peculiarities, recall 
the worm. alanoglossus is therefore regarded as an inter- 
mediate form of great interest, and it constitutes the type of a 
special group (Enteropneusta) which has been established for its 
reception. 
Mr. Peter Ewing showed specimens of the following plants :— 
Cardamine pratensis, Linn.—A remarkable form from Killin, 
showing petaloid calyx, corolla, stamens, and pistil. 
Sagina procumbens, Linn., var. spinosa, Gibs.—Moffat (Mr. J. T. 
Johnstone). 
Rubus Ideus, linn., var. Leesii (Bab).—Moffat. 
Hieracium reticulatum, Lindb.— Killin. 
Epilobiwm montanum, Linn., var. minus.—Moffat. 
Polygonum Persicaria, Linn., var. glanduloswm.—Moffat. 
P. lapathifolium, Linn., var. incanwm.—Moffat. 
Carex rupestris, All.—Killin, 
Poa alpina, Linn.—Killin. 
v. lapponum, Lest.— Forfarshire.

Mr. D. A. Boyd submitted specimens of Schizophyllum commune, 
Fr., from the neighbourhood of West Kilbride. 
Professor James Dunlop, M.D., read a paper on the habits and 
anatomical structure of the Porbeagle Shark (Lamna cornubica, 
 Cuv.), of which two large specimens (male and female) were 
captured in Loch Long on 9th or 10th October last. They were 
caught in a hake-net off Ardentinny, in 30 to 40 fathoms water, 
and were dead when the net was drawn. The female (which 
seemed to have died hard, and had excoriations about the gill- 
openings, probably produced in its violent efforts to free its head 
from the large meshes of the strong entangling net) measured 
from point of snout to the tail about 8 ft. 10 in.; circumference 
about 4 ft. 10 in.; dorsal fin 17 inches in height; upper lobe of 
tail 25 inches, lower lobe 17 inches; colour black on the back
