480 PHILOMYCIDiE. 



Family PHILOMYCID^. 



Genus INCILARIA, Benson. 



Limacella, Blainville, Journ. Phys. Paris, Ixxxv, 1817, p. 443 (not 

 Limacellu, Bravd, 1815); Cockerell, The Conchologist, ii, 1893, 

 p. 193. 



Indiana, Benson, A. M. N. PI. ser. 1, ix, 1842, p. 48G. 



Type, /. bilineatus, Benson. 



Ramie : Inrlia, China. 



" Body liiuacit'orm, entirely naked : foot equalling the body, but 

 separated from it by a groove. Orifices of the generative organs 

 distant, connected by a farrow occupying the entire right side of 

 the body." (^Blainville.) 



Professor Cockerell, in his Check-list of Slugs *, has adopted 

 Limacella, Blainville, 1817, for the present genus, in spite of the 

 fact that Brard had already, in 1815, utilized the name. The 

 latter simply being a synonym of Limax, Prof. Cockerell considers 

 that the rule " once a synonym always a synonym " should be 

 suspended in this case. As this would give I'ise to confusion I 

 have felt it necessary to substitute the next name available for 

 these oriental slugs, discarding Philomycus, Eafinesque (1820), 

 Tebennophorus, Binney (1842), Fallifera, Morse (1864), MegJia- 

 tinum, Hasselt (1824), and Eumeh(s, Bafinesque (1820), the first 

 three applying to American forms and the last two as being 

 insuflicientlv defined. 



470. Incilaria cainpestris, Godwin-Austen.

 Limacdla cainpestris, Cockerell, A. M. N. H. ser. 6, vi, 1890, p. 385 ; 



ibid.. The Conchologist, ii, 1893, p. 193. 



Original description : — " No shell. Animal pale ochre, with a 

 longitudinal dark stripe on the side of the body. Tentacles verv 

 short, only 0-13" [ = 3-5 mm.]. 



"Total'length 1-65" [ = 42 mm.]." {Godwin-Austen.) 



Hah. India : Kholabari, Dafla Hills, Assam. 



This cursory description may be supplemented by the following 

 observations by Prof. Cockerell, who regarded the form as a 

 subspecies of Limacella bilineata : — " Ochraceous yellow, ■with an 

 obscure dorsal and lateral pale brown band, narrow and more or 

 less interrupted. Sole finely laterally transversely wrinkled. 

 Length 23 niillim., respiratory orifice 4 millim. from anterior 

 border of mantle ; sole 4 millim. broad.
