66 LIMAX CINEREO-NIGER. 
The sub-var. palleseens of Lessona is probably only a young form of sub-var. 
maciata, in which the shield has slight grey cloudings and a few irregular black 
spots at its hinder margin, and although described as possessing three rows of black 
spots on each side, the figure shows that the irregular spots are longitudinally split 
and simulate additional rows, as in var. ville. 
The sub-var. seriata differs chietly from the var. vi//e s.s., in the black spots 
not being longitudinally split. 
The sub-var. formosissima differs from var. erwenta in the bluish-black fringe, 
the more sparingly maculate shield, and the described presence of two or three rows 
of black spots on each side (the illustrative figure, however, shows only a single row 
at each side, thongh possibly intended to show two). 
Not hitherto recorded for the British Isles. 
Italy—The var. vi//w is found near Esino, in Lombardy ; and the sub-vars. macu- 
lata and pallescens have been found together at an altitude of 490 metres (about 
1,600 feet), at Varallo, in Val Sesia, Piedmont. The sub-var. seriata has been found 
at Busalla in Piedmont; at Genoa in Liguria; and by the Marchese Paulucci at 
Lueea in Tuscany. The sub-var. erwenta was found at an altitude of 650 metres 
(about 2,130 feet) above Garessio, in the Maritime Alps, Piedmont; the sub-var. 
formosissina was found by Signor Perosino, near Mondovi, at Vicoforte, altitude 
550 metres (about 1,800 feet), and at S. Guiseppe dei Revelli (Less. & Poll., op. cit.).

KEEL and median-line red; with three dark bands on each side. Formula 321 123. 
The var. eallichroa s.st., has the sides of the body yellow, the two upper dark 
bands black and continuous, and the outer or lower band reduced to spots ; shield 
vinous-yellow marbled with black. It is really a primitive form, the marbled shield 
being retained throughout life. 
The var. gualtierii is fuscons with a violet tinge, becoming blackish dorsally, but 
showing a longitudinal red line between the main and outer bands, and traces of a 
second red line between the main and inner bands; shield earthy-brown. 
The sub-var. zonata differs from the var. qualtierii in having the red keel and 
mid-line, and also the two red lines at each side of the body extending up to the 
shield, the intervening spaces being black and the shield brown, 
The sub-yar. arthuri differs from the preceding only in the disintegration of the 
red and black colouring, partially due to the red and black pigments both being 
restricted to the summits of the rugosities. 
Not hitherto recorded for the British Isles.

KEEL and median line red; with two darker zones at each side of the body. 
The formula being (32)1 1(23). 
Though the name geographicus of Renier is probably the oldest name for this 
form, it has not been adopted as his description is so very inadequate. 
The var. daeampi sensu stricto, has the keel and median-line red, with two black 
zones at each side, showing the reddish sides of the body as a reddish longitudinal 
zone on each side; shield brownish-red. 
The sub-var. fusea of Less. & Poll. differs from var. dacampi in the paler red of 
the keel-line and lateral bands, and in the fuscous tint of the sides and shield. 
The sub-var. trilineolata has fuscous-brown sides and shield, and darker dorsal 
ruge; the red ground showing at the keel and as two lateral bands at the caudal 
end, but becoming obscured by the body-colour as they approach the shield.
