Geological Society. — MisceUnneous. 461 



March 8th. 1905.— J. E. Marr, Sc.D., F.R.S., 

 President, in the Chair. 



The following communications were read : — 



1. ' Observations on some of the Loxonematida?, with Descriptions 

 of two New Species.' By Miss Jane Donald. 



Shells having more convex whorls, or less sigmoidal lines of 

 growth than L.sinuosma, cannot be left within the genus Lo.vonema. 

 The two new species described resemble the type in form and in the 

 sinuosity of the lines of growth; but the whorls are ornamented with 

 spiral striae, two of which frequently stand out and give the shell a 

 banded appeaj-ance. Both species are of Silurian age : one was 

 obtained from the Aymestry Limestone near Ledbury, and from 

 beds of about the same age at Llangadock ; and the other from the 

 Wenlock Limestone, Dudley. 



2. ' On some Gasteropoda from the Silurian Rocks of Llan- 

 gadock (Caermarthenshire).' By Miss Jane Donald. 



These fossils occur almost entirely in the state of casts and moulds. 

 Eleven distinct forms have been made out, referable to seven genera ; 

 but only seven are sufficiently well-preserved for specific determina- 

 tion. Five of these are new, including one described in the previous 

 communication ; a new genus is described, for the reception of 

 Euomplialus funatus. The first species described comes nearest to 

 examples placed in the genus Philiospira, as represented by PI. Semele, 

 with which it might be placed in a new subgenus. Three other 

 species, including two new ones, resemble shells referred to Bembosaa. 

 The three species are turriculated, and the band is situated on the 

 angle of the whorls, a little distance above the suture. The specim >ns 

 described come from the horizons of the Upper Llandovery, the 

 Wenlock, the Lower Ludlow (including the Aymestry Limestone), 

 and the Upper Ludlow.
