Mr. H. W. Freston exhibited a male specimen of Asagena 

 phalerata, an extremely rare species of spider, which by itself 

 represents the genus Asagena, v^^hose nearest congener is the genus 

 Steatoda. The present individual is the only male that has been 

 found, at any rate in recent years. Previously the habitat of this 

 species was unknown, but it would now seem to be a simple 

 Theridion snare in grass amongst rocks. This specimen was found 

 in August, on Redbank, above Grasmere. The most striking 

 features of the genus are a denticulated edge to the cephalo- 

 thorax and a denticulated socket in the front of the abdomen, 

 forming a stridulating apparatus, which would produce a squeak- 

 ing noise when rubbed against the rough hinder edge of the 

 thorax. 



Mr. John Butterworth read a paper, entitled, "Further 

 Research on the structure of Psaronius, a Tree Fern 

 of the Coal Measures, and on the Leaf Sheath sur- 

 rounding the Nodes of some of the Calamites of the 

 Lancashire Coal Measures." 



The President, Professor Weiss, and Mr. Mark Stirrup 

 criticised some statements in this paper. 



This paper has been revised by the author and is printed in 

 full, as revised, in the Memoirs.
