" Body limaciform, entirely naked : foot equalling the body, but 

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

 distant, connected by a furrow 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 rise to confusion I 

 have felt it necessary to substitute the next name available for 

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

 Tebennophorus, Biuney (1842), Pallifera, Morse (1864), Meglia- 

 tinum, Hasselt (1824), and .Sum^Ztw, Bafineaque (1820), the first 

 three applying to American forms and the last two as being 

 insufficiently defined. 



470. Incilaria campestris, Godwin-Austen. 



Philomicus (Incillaria] campestris, Godwin-Austen, J. A. S. B. xlv, 



1876, p. 315, pi. 8, fig. 3. 

 Limacella campestris, 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 very 

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



"Total length 1-65* [ = 42 mm.]." (Godwin-Austen.) 



Hob. 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 millim., respiratory orifice 4 millim. from anterior 

 border of mantle ; sole 4 millim. broad.
