 App. anal., Brauer, N. A. figs. 88, 89. 



This species varies considerably according to the strength 

 and abundance of the spots. 



Length 6 lin. ; ex p. 12 lin. 



Hab. not rare in summer, in England and Scotland. 



In Curtis's collection this species stands as L. griseus. 



Case cylindrical, usually set regularly round with small 

 shells, but sometimes also constructed of fragments 

 of plants or wood. 



Ch. nobilis, Kolen., is extremely similar to the pre- 

 ceding species in form, size and coloration ; it is dis- 

 tinguished by a distinct blackish-brown pterostigma, 

 and by the longitudinal veins being regularly punc- 

 tured with brown. Hab. France, Switzerland. Curtis 

 has also ticketed it as L. griseus.
