Lubbock, and more recently Mr. Gamble recorded it as far north as 

 Westmoreland. I took it myself near Coniston in Cumberland, but so far 

 as I know it has never been met with in Scotland. 



Abroad it has been taken in Denmark, Germany, Holland, Austria, 

 France, Switzerland, and the Balearic Isles.

Rhynchodemus Scharffi, v. Graff.

The third Irish species, like the last, was first discovered by the late 

 Miss Kelsall in her garden at Blackrock, Co. Dublin. She handed it to 

 me, saying that she found a sickly-looking worm, which description 

 quite agrees with its yellowish flesh-colour and flabby condition. I 

 recognised it as a new species, but knowing that Prof. v. Graff was then 

 working at his great monograph, I forwarded the specimen to him. A 

 lull description of its external and internal anatomy with figures now 

 appears in the work referred to. The largest of the specimens I have 

 seen measured about 2\ inches (65 mill.), in length, and about |th inch 

 (3 mill.) in width. The lower surface is somewhat lighter than the 

 upper, and, like the last species, it has two small eyes near the anterior 

 end. 



Rhynchodemus Scharffi is closely allied to R. terrestris and also to R. 

 pyrenaicusy but differs from them both in several important structural 

 points. Its size and colour distinguish it at once from R. terrestris
