Mr. T. D. A. Cockerell's Notes on Slags. 287 



Amalia gracilis, Leydig, 1876. 



Smaller than carinata^ and mantle without black sulcus- 

 marking. A. cibiniensis, Kim., is a synonym. 



Amalia gracilis, form budapestensis (Hazay, 1881). 



Hazay's figure represents an elongate slug, nearly utii- 

 colorous palish sepia, tail quite tapering, head and tentacles 

 blackish or grey. 



Amalia baripus (Bourg.). 



Mila.v baripus, Bourg. Moll. Nouv. Lit. ou pea conuus, 18B3-1868, 

 pi. xxxii. figs. 7-10. 



Hab. Syria. 



Bourguignat's figure represents a small pale bluish Amalia, 

 keel pale, head and tentacles pale violaceous ; mantle with 

 the sulcus and a posterior median short line or band black. 



Amalia cristata (Kal.). 



KrynickiUus cristatus, Kal. Bull. Soc. Imp. Nat. Mosc. 1851, tab. v. 

 figs. 1 a, h. 



Kaleniczenko figures a pale reddish-ochre slug ; head and 

 neck blackish ; no sulcus visible on mantle. Tryon's " cris- 

 tata, Kal.," seems more like Eichwaldii. 



Kaleniczenko gives Limax megaspidius, Blainv., as iden- 

 tical with cristatus ; but megaspidius, as attested by the 

 original of Ferussac's fig. 4, pi. vi., in the British Museuni, 

 is a young albino Limax maximus. 



Amalia tyrrena, Less. & Poll. 

 Amalia etriisca, Issel. 



Two Italian species, fully described in Lessona and Pollo- 

 nera's monograph. 



To sura up, I give here a tabic showing the relationships 

 of tiie various forms as nearly as I can make them out.
