Bucholzia appendiculata (Buch.). 



1900. B. «., Michaelseu, Tierreich, x., p. 72. 



This species is not common. It agrees closely with the published 



description of Vejdovsky (27. p. 54), and Michaelsen (19. p. 293). The 



maximum number of setce in a bundle was only four. There was a single row 



of large irregular glands on the epidermis, in each segment, in a line with the 



setse.

Marionina sphagnetorum Vejd. 

 1900. i¥. s., Michaelsen in Tierreich, X., p. 74. 

 This interesting species is a characteristic member of the alpine fauna of 

 Ireland. It is almost invariably to be found in the soil of moors and hills 

 above 500 feet. Specimens are very rarely found in the mature stage. 

 I have only met with them twice, in Kerry and the Isle of Man, on both 

 occasions in the month of June. The length varies from 5 to 20 mm. Set« 

 never more than three. The egg-sac is very large. In immature forms, the 

 intestine is usually covered with large cells full of oil-drops. The blood is 

 usually only very faintly coloured, and in some cases is quite colourless.

This littoral species was originally described by Claparede from specimens 

 found on the Island of Sky in the Hebrides. The description given, though 

 not complete, is sufficient to characterize the species. It has not been recorded 

 since, till I found it on Lambay (tom. cit.). It seems desirable to complete 

 the description.
