COOPER AND LOTDELL : MIDDLESEX MOLLTJSCA. 221 



Other records for this species are Twickenham (S. C. Cockerell, 

 S.G., 1885, p. 116); Hanwell and Perivale (T.M., ii, p. 128). 



8. MiLAx SowEKBTi (Fer.). 



Twickenham, Fulham Palace, Finchley, East Finchley, Highgate, 

 and Neasden. It is plentiful on the higher ground in North Middlesex. 

 The type is the prevalent form. 



Var. nigrescens, Ckl. Twickenham and Finchley. Also recorded 

 for Acton and Bedford Park (T.M., ii, p. 156). 



Var. hicolor, Ckl. Ealing (T. D. A. Cockerell, S.G., 1887, p. 187). 



'Szx. fuscocarinata, Ckl. Bedford Park (T.M., ii, p. 156). 



9. MiLAx GAGATEs (Drap.). 



We have failed to find this slug, although it is said to be fairly 

 common. It is recorded for Hornsey and Islington (T.M., ii, p. 147). 



Var. plumlea, Moq. Ealing (T. D. A. Cockerell, S.G., 1887, p. 187); 

 Acton, Bedford Park, and Hampstead (T.M., ii, p. 144). 



Var. rava, "Williams. Hornsey and Crouch Hill (T.M., ii, p. 145). 



Var. pallidissima, Pollon. Highgate (T.M., ii, p. 146). 



10. VlTEINA PEILTJCIDA (Miill.). 



Harefield, Staines, Stanwell Moor, Hampton Court, Acton, and 

 Neasden. It is a local species and does not appear to live in the 

 eastern part of the county. 



11. VlTKEA CKTSTALLINA (Miill.). 



Harefield, Uxbridge, Yiewsley, Stanwell Moor, Twickenham, Acton, 

 Fulham Palace, Stanmore, East Finchley, Highgate Woods, Wood 

 Green, and Ponders End. Abundant among rotten leaves in suitable 

 localities. 



12. ViTEEA LTJCiDA (Drap.). 



Grounds of Fulham Palace, where it is probably an introduction. 

 We have not met with genuine V. lucida anywhere else in the 

 county. It is, however, recorded for Isleworth (F. G. Fenn, S.G., 

 1887, p. 139, and Mr. B. B. Woodward has specimens thence). South 

 Kensington (T.M., iii, p. 27). 



13. VlTREA OELLAEIA (Miill.). 



It appears that two species {V. cellaria, s.s., and V. Scharjfi) have 

 hitherto been included under this name. We believe typical V. cellaria 

 is not uncommon in Middlesex, but we can only record it with certainty 

 from Muswell Hill and Highgate Woods. 



14. ViTREA ScHAEFFi, Keunard. 



This newly described species we have found at Harefield, Neasden, 

 Einchley, and East Finchley. No doubt it occurs elsewhere, but we 

 did not attempt to differentiate it from V. cellaria until last autumn ; 

 consequently our previous notes may refer to either species, and are 

 now useless.
