^98 PROCEEDINGS OP THE QUEKETT MICROSCOPICAL CLUB. 



-of the Club. Nomination forms on behalf of three candidates were 

 read for the first time. 



The chairman then called upon the Secretary to read Mr. G. T. 

 Harris's paper on Schistostega osmundacea Mohr. 



After some remarks by Messrs. Scourfield, Grundy, Hinton 

 and Burton, a hearty vote of thanks was accorded to Mr. Harris 

 for his interesting paper. Mr. Scourfield exhibited a specimen of 

 Schistostega in which the luminous appearance was very beauti- 

 fully shown by means of a vertical illuminator. 



Mr. F. J. Perks then read a paper by Messrs. Williamson and 

 Soar on Lebertia sefvei Walter. This water- mite is of interest on 

 account of the fact that the species was previously recorded as 

 having been found only in Swedish Lapland. The discovery of 

 the Arctic form in Dartmoor brings the number of the Britannic 

 species of this genus up to twelve. A single specimen of which 

 the sex cannot be determined was taken by Mr. D. J. Scourfield 

 at Fernworthy Bog, Dartmoor, in August 1917. 



At the meeting of the Club on April 9th Sir Nicholas 

 Yermaloff, K.C.B., will read a paper, illustrated by lantern slides, 

 entitled " Notes on Some Intermediate Forms of the Genera 

 Cymbella and Navicula."
