THE NAUTILUS. 87 



(5.) Limax maximus " L.," Auctt., var. vulgaris ^loq. 



Tliis hilt- the dorsal black bands continuous. One from Lexington, 

 Va. (Prof. Morrison). 



(6.) L. maximus var. cellarius D'Argentville. 



The bands on the back interrupted at intervals. Fifteen speci- 

 mens, some tending toward var. ferussaci Moq., from Lexington, 

 Va. (Prof. ^Morrison). 



(7.) L. maximus var. maculatus Picanl. 



The back -with black spots irregularly placed. One very nice 

 one from Burlington, IST. J. (]Mr. Binney). 

 (8.) Helix nemoralis L. 



Mr. Binney has sent me several living examples from Burlington, 

 N. J., among which the var. rubella greatly preponderates, gvettardia 

 and cuvie7-in being the only other varieties represented. It is here 

 interesting to notice, that at Burlington, where the species has been 

 long established, it varies much less than at Lexington. The red 

 forms so rare at Lexington, largely preponderate in the Burlington 

 sen dings. 



Prof. Morrison has lately sent me several more varieties from 

 Lexington, ten being new, and two already recorded in Europe. 

 These latter are var. requienia Moq. (^petiveria 10345) and var, 

 libellula 1(234)5 Kreglinger. Tlie new ones will be recorded later. 

 (9.) Helix hispida var. concinna ( Jeffrey's). 



Mr. Binney sent me a shell found at- Montreal, referable to this 

 form. It is pale horn color, max. diam. 8|, alt. 4f mill. H. concinna 

 was considered by Dr. Gwyn JefiVeys a valid species, but it cannot 

 be .separated on sufficient grounds from H. hispida L. 

 (10.) Helix cantiana Mont. var. minor ^loq. 



Mr. Binney has sent me an example which he received from 

 Mr. F. R. Latchford, labelled "Citadel, Quebec, Aug. 12, 1886." 

 It is smaller and thinner than the type, with the least tinge of red 

 outside the outer lip. Max. diam. 15, alt. 10 mill. Figured in 

 Bull. Mus. Comp. Zool. Vol. xiii, No. 2 (188(3). PI. I, tig. 13. 

 This form, which I believe is very constant in its characters, is a 

 variety of Helix galloprovincialis Dupuy, which, however, is itself 

 undoubtedly a variety of H. cantiana.
