slightly raised in the centre and more so towards the aperture, which 

 appears to be subcircular, with the inner lip strong and thickened. 

 Surface of whorls ornamented by transverse, obliquely curved, 

 reo-ular, and equidistant lamellar ribs. Umbilicus small and 

 apparently closed. 



Kemarks. — This form certainly does not belong to the genus 

 Enomplialus. Its whole appearance is trochiform, and it bears 

 a close resemblance to Trochus Stiixbergi (Lindstrom),^ but differs 

 by the umbilical surface being flatter, by the marginal ridge being 

 less developed, and by the greater strength and regularity of the 

 o-rowth-lamellEe on the surface. Its ornamentation is not so 

 coarse as in Tr. imdulans (Lindstrom),- but the shape of this species 

 and its umbilical surface are very similar. The characters of the 

 mouth and umbilical surface distinguish it from Callonema obesum 

 (Lindstrom),^ with which at first sight it bears some resemblance in 

 shape and ornamentation.

lY. Notes on the Lower Carboniferous Fishes of Eastern 



Fifeshire. 



By Dr. R. H. TaAauAm, F.R.S., F.G.S. 



(Bead before the Eoyal Physical Society of Edinburgh, January 16th, 1901.) 



OT much has as yet been done in the way of cataloguing the 

 fossil fishes of the Lower Carboniferous rocks of Eastern 

 Fifeshire. A few species and localities were noted by the late 

 Eev. Thomas Brown in I860* and by Mr. Kirkby in 1880,^ and 

 the late Mr. Eobert Walker published a paper in 1872 ° in which 

 he described what he supposed to be a new species of Amhlypterus 

 (A. anconoeechmodiis) from the Oil-shale works at Pitcorthy, near 

 Anstruther. In this paper Mr. Walker drew attention to the 

 abundance and variety of fish-remains in the oil-shale and ironstone 

 worked at that locality, promising to describe them in detail after- 

 wards — a promise which he was never able to fulfil. After his
