NOTES. 

 Physa heterostropha, Say, in South Staffordshire. —in 1S99 



Mr. [. .Madisnii recorilcd this s|)ccies as liaviii<; been taKcn In' him in July 189S, in 

 a pool at the west side of liiiniinghani (Journ. of Conchy., vol. 9, p. 152). I am 

 now able to add a further locality for this interesting species, viz. a mill pool near 

 Wedneshury, South Staffordshire. I am of opinion that it has been here for some 

 length of time, as it is well established and almost as abundant as its companion 

 Lhnnar.a pernjcr. I may mention that the pool is supplied by the River Tame, 

 which pn)l)al)Iy accounts for its presence here. — J. LlNTOX. 



Amalia gagates, Drp., at Sutton Coldfleld.- -Although this district 



lias been well worked during the past few years, no previous record exists of the 

 occurrence of Amalia gagates, Drp. It may therefore be of interest to note that I 

 have recently collected this species on two separate occasions. The identification 

 has been verified by Mr. Walter E. Collinge.^ — PI. Overton. 



Umax maximus, L., at Los Angeles, California.- When at Los 



Angeles last sunnncr, I liad some very enjoyable visits at the house of Dr. R. E. C. 

 .Stearns. On one of these occasions he took me out to see the Limax i/iaximus in 

 his garden, and kindly gave me several specimens. The purpose of this note is to 

 record their variation, which is always of interest. Two forms were found, as 

 follows: 



(i.) Mantle darlc grey; its anterior and lateral margins pale, spotted with black. 

 Body above dark giey with three light bands, which are more or less edged with 

 black spots or interrupted stripes. .Sitles jiale, mottled with grey. 



(2.) Mantle grey with a few black spots. Body dark grey with obscure black 

 spots, and a pale dorsal stripe on posterior two-thirds. — T. D. A. Cockerei.l.
