Mr. T. D. A. Cockerell's Notes on Slugs. 387 



Limacella striata (Hass. 1824). 



Hah. Java. 



See Bull. Soc. Nat. iii. p. 82, 1824, and also Fe'russac, 

 Hist. Moll. ii. p. 96', pi. 8 E. %. 1 (as strigatum), and W. 

 Keferstein, Mai, Blatt. xiii. p. 64, pi. 1. figs. 1-4 (1866). 



Limacella picta (Stol.) . 

 Meghhnatmm pictum, Stol. Journ. As. Soc. Beng. xlii, pt. 2, p. 30. 

 Hah. Island of Penang. 



Limacella reticulata (Hass., Fer.). 

 A doubtful species. 



Limacella cylindracea (F^r.). 

 Meghhnatium cylindraceum, F^r. Hist, Moll. pi. 8f. figs. 8, 9. 



A very doubtful species. In the figure the mark where 

 the respiratory orifice should be looks more like an injury. 



IV. Desceiptive Notes on Various Species. 



Under this head I will note a few species belonging to 

 genera which will not be specially reviewed in the present 

 series of papers. 



^'Arion^'' aterrimus. Gray. 

 Avion aterritnus, Gray, Cat. Pulm. 1885, p. 55. 



Length 36 millim. ; mantle, length 22 milllim. ; respira- 

 tory orifice 8 millim. from anterior border of mantle ; sole 

 11 millim. broad. Entirely black, mantle granulose, tuber- 

 culate anteriorly, oval, produced and bluntly angled behind ; 

 body smoothish, with linear grooves from mantle to foot, 

 about 2 millim,, more or less, apart. Body not keeled. Tail 

 flattened, mucus-pore inconspicuous or none. Sole apparently 

 "undifferentiated into parts. Edge of foot sulcate. 



This description is from an alcoholic example in the 

 British Museum marked '"'■Limax {Arion) allerian [sic], S. 

 x\frica." There can hardly be a doubt that it is Gray's A. 

 aterritnus, although the description in Cat. Pulm. is so very 

 short.
