Observations. — I was fortunate enough to secure a fine speci- 
men of this species, together with other cephalopods, from the 
locality named above at Caton. Dr. A. H. Foord, Geol. Mag., 
dec. iii.. Vol. viii., 1891, p. 481, quotes Pleuronautilus nodoso- 
carinatus, Roemer, sp., P. armatus, Sow. sp., Solenocheilus 
latiseptatus, de Kon. sp., and Actinoceras sulcatulum, M'Coy, 
from the same locality. I also obtained there Glyphioceras 
Phillipsi, Foord and Crick, and Posidoniella laevis. 
I recognised a somewhat crushed example in the Geological 
collection of St. Mary's College, Stoneyhurst, from the Millstone 
Grit shales of Sales wheel in the bank of the Ribble where it 
is associated with P. falcatus sp. J. de C. Sow., sp. Glyphioceras 
bilingue, Salt, sp., Orthoceras, sp., 0. asicululare, Brown, fragments 
of what I take to be Pleuronautilus nodoso-carinatus , Roem., sp., 
Pterinopecten papyraceus, Sow., sp., Pseudamusium fibrillosum^ 
Salt, sp., Chaenocardiola footii, BaHy, sip., smd Posidoniella laevis, 
Brown, sp. 
The Sales wheel shales are referred to the horizon of the 
Sabden shales, overlying the Kinderscout or 4th grit. The zone 
Goniatite is Glyphioceras bilingue, Salt, sp., which ranges from 
the upper part of the Pendleside group to the Sabden shales. 
The Caton shales are probably about the same horizon. 
I also found the body chamber of a full sized example of the 
species in the Marine series of Congleton Edge, 600 feet below 
the Millstone Grit in the zone of Glyphioceras spirale. An exami- 
nation of the fine specimen in the Manchester Museum, which I 
think is the one figured by Wild, Op. supra cit., convinced me 
that he had not only erroneously referred two forms to N. cyclo- 
stomus, Phillips, sp., but had confounded together two Nautiloids
