tooth, and this of a peculiar form, was compared with the corre- 

 sponding bone in Ischyodus, Edaphodon, Elasmodiis, Ganodus, Chi- 

 mcera, and Oallorhpichus. The form of the tooth appeared to agree 

 better with that of the last-named genus than with any of the 

 others ; and the author therefore proposed to call it, in allusion to 

 the form of the tooth, Cullorhyachus Hectori. 



" On a Bone-bed in the Lower Coal-measures, with an enume- 

 ration of the Fish-remains of which it is principally composed." By 

 J. W. Davis, Esq., F.L.S., F.G.S. 



In this paper the author described a thin bed composed chiefly of 

 remains of fishes, which rests immediately upon the " Better-bed 

 Coal " of the Lower Coal-measures in Yorkshire. The bed varies 

 from a quarter to five eighths of an inch in thickness, and is over- 

 lain by a thick bed of blue argillaceous shale, containing remains of 

 plants. The author described the order of the deposits both above 

 and below the " Bone-bed," and gave a list of the organisms of 

 which remains are found in the latter, including species of Gyra- 

 canthus, CtenacantJms, Lepracanthus, Acanthodes, Pleuracanthus, 

 Orthacanthus, Diplodus, Pleurodus, Jlelodits, Cladodus, Poscilodus, 

 Petalodus, Harpacodus, Ctenoptychius, Megcdichthys, HoloptycJiius, 

 Strepsodus, Acrolepis, Platysomus, Acanthodopsis, Ampldcentrum, 

 Rhizodopsis, Cyclopty clans, Gyrolepis, Pcdceoniscus, Ccelacanthus, and 

 Ctenodus. The author also described spines which he regarded as 

 indicating two new genera of Elasmobranchs — one probably allied 

 to PleuracantJms, and the other (^Hoplonchus) allied to Onchus and 

 Momacanthus. Bones belonging to the Labyrinthodont genus Locc- 

 omnia are met with rarely in the deposit. 



" Note on a Species of Foraminifera from the Carboniferous 

 formation of Sumatra." By M. Jules Huguenin. 



The author described some globular Foraminifera, belonging or 

 allied to Fusidina, from a Carboniferous deposit containing Producti 

 and PhUlipsice, which occurs N.E. of Padang and S. of the Lake 

 of Singkarak in Sumatra. The author described the structure of 

 these fossils, which he compared with Fusulina cylindrica and F. 

 depressa^ and arrived at the conclusion that they belong to a new 

 genus, to which perhaps the North-American Fusulina robusta 

 also belongs.
