 Zonites cellaritis, W. G. Binney, Terr. Moll., v, 112. 



A European species, introduced by commerce into Philadelphia,, 

 Astoria, K. Y., Connecticut, Providence, Newport, E. I., Bostofi, Salem, 

 Lynn, Marblehead, Portland, Me., Halifax, N. S., and Portland, Oieg. 

 It is common in cellars and gardens in Boston. It has also been carried 

 to Australia. 



Animal : Upper surface light indi go-blue, darkest on the head, neck, 

 Fig. 494. and eye-peduncles, collar greenish, eyes black; foot 



narrow and slender, not much exceeding in length the 

 diameter of the shell, terminating acutely. A distinct 

 Amtiia) of z.ceiiarius. locomotivc disk : longitudinal furrows above the mar- 

 gin of the foot, uniting over a longitudinal mucus pore* of the same 

 nature described under Z. fuliginosus (p. 205). 



Jaw strongly arcuate, ends bluntly rounded ; center of anterior sur- 

 face slightly striate 5 lower margin smooth, with a median jirojection. 



Lingual membrane quite peculiar; the figure (Terr. Moll,, V, Plate II, 

 Fig. G) shows one half of one transverse line with the median tooth; 

 14-1-14 teeth. The central tooth has side cusps, but not cutting 

 points, as in Z. Iccvigatus. There can hardly be said to be one perfect 

 lateral, the first side tooth being peculiar in having an inner side cut- 

 ting point instead of the usual outer side cusp and cutting point. The 

 second side tooth is like the first, the third is decidedly modified, the 

 fourth is a true marginal of the usual aculeate form. 



The figures of dentition of the foreign form (by Lehmann, Lindstrom, 

 Semper, &c ) agree with mine. 



I am not aware of this peculiar dentition having been noticed in any 

 other species but aUiarius. 



Genitalia (Terr. Moll., I, Plate VII, Fig. I) with no accessory organs. 



* No mention of the caudal pore is made by Draparnaud, Moquiu-Tandon, Forbes 

 and Hauley, Keeve, Gray, or Gwyn Jeff'reys. It is also overlooked in Semper, Phil, 

 Archip.
