288 APPENDIX. 



Vol. iv. p. 13. LlMAX AGRESTIS. 



There is much confusion in Turton's notices and figures of the 

 shell of this common slug. His animal is agrestis, his descrip- 

 tion of the shell that of either agrestis or Sowerbii, whilst his 

 figure was copied from Brard's, Plate iv. Fig. 8, concava. As the 

 latter is declared by its describer to be truly the shell of agrestis, 

 the synonymy should stand thus : 



Limacella obliqua, Brard, p. 118, pi. 4, f. 5, 6, 13, 14, 17. 

 Limacdlus obliquus, Turton, p. 26 (pi. 3, fig. 16, as variegatus). 



Mr. R. Gibbs has found a curious monster of this species, 

 having the upper tentacula united into one. 



Vol. iv. p. 17. LlMAX ARBORUM. 



This species appears to be very generally distributed. We 

 found it plentifully in September, 1852, creeping on bare stones 

 and rocks at an elevation of above fifteen hundred feet, near 

 Connor Cliffs, above Dingle, in Kerry. The locality is worthy of 

 record, as being entirely devoid of trees. Mr. E. J. Lowe ob- 

 serves, that near Nottingham it prefers walnut trees. The same 

 active observer has found a curious pigmy variety of the scarce 

 Limax brunneus near Nottingham. 



Vol. iv. p. 19. Limax flavus. 



Although the shell described by Turton seems to be truly that 

 of this species, his figure is copied from Brard's obliquus (pi. iv., 

 f. 6), which is really agrestis; the synonymy would stand better 

 thus : — 



Limacella unguiculus, Brard, p. 115, pi. 4, f. 14, 12, 3, 4. 

 Limacdlus variegatus, Turton, p. 25 (shell), fig. 15, as unguiculus. 



It is just possible that Turton's description of the animal of 

 flavus may refer to Soioerbii ; the figures of Limacella concava, 

 Brard, p. 121, pi. 4, f. 7, 8, 16, 17, 18 (copied as Limacellus 

 obliquus, by Turton, fig. 1 7), may belong to Limax gagates, or even 

 L. brunneus.
