THE NAUTILUS. 31 



miles north of Victoria (Taylor). It is figured in ord suppl. Terr. 

 Moll. U. S., PI. viii, fig. f. On ]). 205 of iiis 3rd suppl. Mr. Binney 

 refers to a slug from British Columbia, apparentlyL. hemphilli AV. 

 G. Binney. Limax hemphilli is, I think witliout doubt, a variety 

 of Agriolimax Berendti (Strebel), and Avas hardly to be expected so 

 far north. 



In my copy of PL viii of INIr. Binney's 3rd Supi)l. Terr. Moll., 

 figures of Ag. hemphilli and Ag. montanus have some appearance of 

 dark lateral bands, owing to the ink having run in printing. All 

 the four forms of Agriolimax figured on that plate resemble Ag. Icevis 

 in general appearance, and of course, have no dark bands. I found 

 them to differ slightly in the position of the longitudinal line or 

 groove on the margin of the foot, and the figures given of the foot- 

 margins were intended to show this difference. It will be seen that 

 in montanus the line is near the upper edge of the margin, in occi- 

 dentdlis it is lower, in hyperboreus it is about median, and in hemp- 

 hilli it is nearest the lower edge. I have not, however, examined 

 this character in a sufficient number of specimens to say whether 

 it is of really of classificatory value. 



(2) Prophysaon pacificum Ckll. : Victoria, Vancouver Island 

 (Wickham). Figured in Binney's 3rd Suppl. Terr. Moll. U. S., 

 PI. vii. In this w'ork, PI. vii, fig. e, is the jaw of P. humile, and 

 fig. f that of P. pacificum : these names are unfortunately transposed 

 in the plate, on p. 225. P. pacificum Avas described from tAvo speci- 

 mens, one of which is now in the British Museum, and the other in 

 the U. S. National Museum. 



(3) Prophysaon andersoni (Cooper) var. hemphilli (B. & B.) : 

 British Columbia, six specimens {Rev. J. H. Keen). 



(3b) Prophysaon andersonii var. nov. pallidum. Paler, ochre- 

 ous, the bands on mantle evanescent, reticulation on body not dark, 

 back not darker than sides, neck pale. Two specimens from British 

 Columbia {Pev. J. H. Keen), the largest 46 mill, long (in alcohol). 

 One has the tail cut ofl^, in the same Avay as has been described in 

 other species of the genus. All the eight examples of Prophysaon 

 sent by Mr. Keen have the sole strongly Avrinkled. 



(4) Ariolimax columbianus (Gould) forma typicns. Without 

 black spots. British Columbia, two specimens (Rev. J. H. Keen). 



(4b) Ariolimax columbianus i'orm'd maculahts Ckll. This spotted 

 form seems to be rather more frequent than the type.^ Mr. Keen's 



1 Ariolimax subsp. californiciis forma nov. niaculatus is a "precisely sim- 

 ilarly spotted form of the Califoniian subspecies. There is an example in the 

 British Museum from Mr. W. G. Binney, 45 mm. long.
