Reports and Proceedings- 
wliich the above genera of fossil fishes bave been supposefl to be 
distinguisbed in tbe case of specimens from the Carboniferous 
series. In Amblypterus be distinguisbed five types among tbe 
species referred to tbat genas by Agassiz, viz. : — I. Of A. latus; II. 
A. macropterus = genus Rhabdolepis, Troscb. ; III. Of A. strialus 
= Cosmoptychius, g. n. ; IV. Of A. nemopterus — genus Elonichthys, 
Gieb. ; V. Of A. punctatus = Gonatodus, g. n. In Palceoniscus he 
distinguisbed tbe following types : — I. Of P. Freieslebeni ; II. Of P. 
Duvernoyi — genus Amblypterus, Ag. ; III. Of P. striolatus = genus 
Elonichthys, Gieb. ; of P. ornatissimus r= Rhadiniclilhys, g.n. ; VI. Of 
glaphyrus = Acentrophorus, g. n. ; VII. Of P. catopterus =z genus 
Didyopyge, Egert. He further discussed at great lengtb the charae- 
ters and affinities of the genera Gyrolepis and Pygopterus, tbe former 
of wbicb be regarded as untenable, on tbe ground of its being 
founded on fragmentary remains of fishes belonging to several otber 
genera ; and tbe latter as divisible into the following groups : — I. 
Type of P. Ilumboldtii, Permian only ; II. Type of P. Paclclandi= 
Elonichthys, Gieb. ; III. Type of P. GreenocJcii=Nematoptychius, 
g. n. Tbere are no Carboniferous species of Pygopterus proper. 
2. “On tbe Circinate Vemation, Fructification, and Varieties of 
Sphenopteris affinis, and on Staphylopteris ? Peachii, Etberidge and 
Balfour, a Genus of Plan f s new to British Rocks.” By C. W. Peacb, 
Esq., A.L.S. Communicated by Robert Etberidge, Esq., F.R.S., 
V.P.G.S. 
The author noticed the occurrence in the Carboniferous sbales near 
West Calder (Edinburgh) of abundant remains of the fern described 
by Lindley and Hutton as Sphenopteris affinis, dwelling especially 
on tbe circinate vernation and supposed fructificalion of the plant. 
Witb it were found many fragments of small flower-like plants, 
whicb had been referred to the genus Staphylopteris, Presl, tbe 
fructification especially resembling that ascribed to tliat genus. Tbe 
author considered tbat in all probability tbe Staphylopteris was 
parasitic upon tbe Sphenopteris, perbaps after tbe fashion of Cuscuta 
upon flowering plants. 
Discussion.— Mr. Carruthers spoke in high terms of appreciation of Mr. 
Peach’s work in nearly all departments of Natural History. The greatest credit 
was due to him for his exceedingly careful observations. At the same time Mr. 
Carruthers was compelled to differ from him with regard to the plants which had 
been brought before the Society on this occasion. The structure of the fruit in 
some of Stur’s coal-plants is the same as in the living Hymenophyllum, consisting of 
two valves peculiarly arranged, the lower pinn® of the fronds being fertile and 
moditied accordingly. The same thing seems to have occurred in Sphenopteris affinis, 
except that the lower pinn® retained their normal structure, and the apical pinn® 
were moditied as the fruit-bearing portion, which had been regarded as formiug the 
peculiar genus Staphylopteris. 
3. “On tbe Occurrence of a Macrurous Decapod ( Anthrapalcemon 
Woodwardi, sp. nov.) in the Red Sandstone, or Lowest Group of tbe 
Carboniferous Formation in tbe South-East of Scotland.” By Robert 
Etberidge, Esq., Jun., F.G.S. 
After giving a detailed bibliography of the Palmozoic Malacostra- 
cous Crustacea, tbe author described the remains of a small Crus- 
tacean from the lower group of tbe Carboniferous formation near
