NATURAL HISTORY SOCIETY OF GLASGOW. 159 



Mr John Young, F.G.S., exliibited some microscopic prepara- 

 tions of the shell of Estheria pimdateUa (Jones), a new species of a 

 large Phyllopod Crustacean, found by him in the upper shales of 

 Arden quarry, Thornliebank, and which has since been discovered 

 by Mr James Thomson, F.G.S., at the Linn Spout, near Dairy, 

 where they crowd the surfaces of certain shell beds on the same 

 geological horizon as those in the Thornliebank district. Prepara- 

 tions of the shell of this Crustacean, as seen under the microscope, 

 show a beautiful punctate or minute honeycomb style of orna- 

 mentation, by which this species is distinguished from other forms 

 of Carboniferous Estheria, as well as from the shells of certain 

 bivalve molluscs which it resembles, and with which it is liable 

 to be confounded.

Mr Thomas Chapman in the chair. 



The following gentlemen were elected members: — Mr John 

 Kirsop and Mr James Park as resident members ; Mr Alexander

SPECIMENS EXHIBITED. . 



Mr James Coutts exhibited, with remarks, two moths, Bunoea 

 alcinoe and Gynanasa isis, both from Natal. 



Mr Charles Eadie exhibited two fine specimens of a fossil fish, 

 the Little Capelin, Mallotus villosus (I), from Canada. These 

 specimens, which Mr Eadie had presented to the Hunterian 

 Museum, were described by Mr John Young, F.G.S., who stated 

 that the fishes are found enclosed in nodules of clay, and are 

 interesting as belonging to a species that is supposed to be still 

 living in northern seas. They have also been found embedded in 

 clay deposits in Greenland, the nodules in which they are enclosed 

 being formed by the decay of the soft parts of the fish hardening 

 the surrounding clay. 



Mr Young exhibited, with remarks, a very finely-preserved fin 

 spine of a fossil Carboniferous fish, Leptacanthus Jenkinsoni (M'Coy), 

 which was obtained from the clay band ironstone in the Carbonifer- 

 ous limestone series at High Blantyre. Mr Young stated that, so
