NOTES. 



Helix lapieida m. SinistrorSUm.— This form was named by C. A. Westerlund 

 in 1871, so Mr. Partridge's find (p. 180) is not an absolute novelty, though it is 

 very interesting. — T. D. A. Cockerell. 



Triehomya, von Ihering* (see p. 186).— This may I suppose remain, on 

 account of its different derivation, but it is uncomfortably similar to Trichomyia, 

 Haliday, a genus of Diptera.— T. D. A. Cockerell.
