“Kammleisten”’ of Professor Iritsch. 91 
“ Kammplatten,” though Mr. Barkas ascribed them to Cteno- 
ptychius. Mr. Barkas subsequently* named them C. wnilate- 
ralis, and refigured them in a plate accompanying a communi- 
cation to the ‘ Colliery Guardian’+, and in his Atlas of 
Carboniferous Fossils f. 
During the past winter Mr. John Young, F.G.8., exhibited 
to the Natural-History Society of Glasgow§ a specimen from 
the Blackband Ironstone shales of the Airdrie coal-field, which 
he referred to the “ Kammleisten” of Ophiderpeton, atter 
comparing it with Prof. Fritsch’s figures and descriptions. 
Forms of the same general description have been lately de- 
tected in the Edge coal series of our own neighbourhood—that 
is, near the base of the middle division of our Scottish Carbo- 
niferous system. Dr. Traquair’s Huctenius elegans, founded 
upon specimens obtained from the Black-band Ivonstone, 
worked at Burgh Lee, near Edinburgh ll, 1s evidently a 
‘“‘Kammplatte.’ Dr. Traquair, who has, with great kindness, 
given me much help in the preparation of this paper, tells me 
that he had independently arrived at the same conclusion. My 
friend Mr. W. ‘I’. Kinnear, still more recently, has discovered 
undoubted specimens of “ Kammplatten ” at the same locality. 
On a small slab, which he has generously allowed me to keep 
for my collection, there is an entire plate; and close beside it 
there is the handle of a second. They are associated with a 
specimen of Ctenoptychius pectinatus, Ag., which is a common 
fossil at the locality. 
I am greatly indebted to my friend Mr. Joseph Taylor, of 
Shire Moor, for the opportunity of studying three comb plates 
from Newsham. Mr. John Ward, F.G.S., of Longton, has also 
kindly allowed me to see some good specimens from the same 
locality. They do not appear to be rare on the horizon of the 
Low-Main seam ; but they have not yet been recorded else- 
where except at the Scottish localities mentioned. Probably 
as attention is directed to them it will be found that they are 
not unfrequent in the Carboniferous rocks of this country. 
The animals to which they belonged seem to have ranged from 
the Permian (in Bohemia), through the Coal-measures (in 
Northumberland and Lanarkshire), down to the base of the 
Carboniferous Limestone series (in Midlothian).
