Cardium Wooluoughi ', sp. nov. 

 [The species here referred to is not rare, but does not appear to have been 

 figured or described by any Continental writer. In shape it is roundly ovate, 

 tumid, and nearly equilateral, garnished with twenty-five to thirty narrow 

 rounded prominent ribs continued below the lower margin with rather wider 

 interspaces. The surface is much decorticated, leaving four or five ridges 

 marking probably stages of growth. Mus. Ipswich.]
