60 Till; NAUTILUS. 



thai name being pre-occupied, J gave the new name Eulota gainesi 

 to inv specimens. Further atudy of the group with mure material, 

 and notes on the type specimen of lata, kindly supplied by Prof. 

 Dall, .shows that E. gainesi is perfectly distinct from lata. 



I propose now to designate as E. gudeana n. sp., a large greenish 

 species, also from Ushika, Teshio prov., Hokkaido, which has some- 

 what the aspect of Natalino caffra, and which differs from E. gainesi 

 in the broader form, less plicate surface, and the peristome, which 

 is barely everted outwardly, becoming expanded below and reflexed 

 at the columella, whorls 5.

I regard Helix lata Gld. (not Pfr.) as a less-developed race of this 

 species ; and the name being pre-occupied, I propose to call this 

 Hakodate form Eulota gudeana Jtakodatensis. It is more fragile than 

 gudeana, smaller, diam. .about 2G mm., and yellowish-brown, with 

 two brown bands above. Types of E. gainesi, E. gudeana and E. g. 

 hakodatensis are in the collection of the Academy. 



Figures of these several species and races will appear in the Pro- 

 ceedings of the Academy of Natural Sciences. 



Eulota callizona dixoni n. var. 



Shell rather narrowly umbilicate, globose-pyramidal with high- 

 conic spire, rather thin and smooth ; greenish-corneous, usually with 

 a black brown peripheral band, a narrower subsutural band, and a 

 large basal patch formed of the united basal band and umbilical 

 patch. Aperture rounded-lunate, oblique, the lip broadly expanded, 

 thickened within, reflexed below, purplish flesh colored, and at the 

 terminations of the bands purple-black. Alt. 32^, diam. 33 mm.

This form has hitherto been erroneously united to E. callizona 

 Crosse, or E. amalice Kobelt. The latter is probably nearest, its area 

 of distribution lying chiefly northeast of that of dixoni, while E. cal- 

 lizona is undoubtedly the northern fringe, so to speak, of the amalice 

 stock, and came in all probability from the Hakone region. 



A small form before me from Hagi, Nagato Province, is clearly 

 related genetically to dixoni, and not referable to callizona. 



GENERAL NOTES. 



Apropos of the note on Bathysciadiunt in the last number (p. 48), 

 it might be well to state that Prof. Wilcox found Acmeea fragilis of 

 New Zealand to be hermaphrodite, and exceptional specimens of 

 another species have also been stated to have both male and female 

 reproductive organs. These facts render the case of Bathysciadiuin 

 less exceptional. It is noteworthy that the deep-water limpets, like 

 the Chitons, belong to the lowest groups in their respective orders.
