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



pared the above form very carefully with A. gagates, and it 

 certainly seems worthy of a subspecific name. 



Amalia mediterranea, forma nov. similis. 



Length (in alcohol) 36^ millim. ; strongly keeled, keel 

 rather flexuose. Opaque, wrinkly-rugose, grooved lines on 

 body well marked, and connected by a network of smaller 

 ones. Colour black, except sole, mouth-parts, and parts 

 covered by the mantle, which are pale ochrey. Mantle 

 emarginate behind. Lateral areas of sole narrower together 

 than median area and greyer, in fact quite greyish, the median 

 area being ochrey. Sole 6 millim. broad, median area 

 3^ millim. broad. 



Described from a specimen kindly sent to me by Mr. Pollo- 

 nera, found at Catania, Sicily. It is evidently very close to 

 the Algerian form described above, but not identical. In 

 Lessona and Pollonera' s l Monograph,' p. 59, there is a refer- 

 ence to this Catania variety under A. gagates. Mr. Pollo- 

 nera tells me that the sides of this form are sometimes pale. 



Amalia ichnusce, Less. & Poll. 



A Sardinian form, perhaps a variety of gagates, from which 

 it differs only by its smaller size and somewhat in its geni- 

 talia. Mr. Pollonera thinks that this might better be con- 

 sidered a subspecies or variety of gagates than any of the three 

 Sicilian species described by him which have been referred 

 thereto. 



Amalia Doderleini, Less. & Poll. 



Found at Palermo, and recognized by the black band on 

 the mantle, which Mr. Pollonera says is never seen in the 

 pale varieties of gagates. 



Amalia {Monterosati , var. ?) sicula, Less. & Poll. 



This Palermo species, Mr. Pollonera informs me, is larger 

 than the Catania gagates (my similis), much less rugose, and 

 the shell is quite different, being like that on which Bourgui- 

 gnat founded his genus Palizzolia. 



Amalia [scaptobia var. ?) insularis, Less. & Poll. 



A third species found at Palermo. Mr. Pollonera tells me 

 it externally resembles carinata, Risso, much more than
