180 A MANUAL OF AMERICAN LAND SHELLS. 



Animal black, mantle dirty yellow, with black spots, which are to 

 be seen throngh the shell. Foot long, narrow. Eye-peduncles long 

 and proportionally rather thick. Tentacles short, blunt. (Morch.) 



Fig. 173 is copied from an original drawing by Morch, I. c. I have 

 not seen the species, which certainly must be nearly allied to, if not 

 identical with, fulvus. 



Zonites Biiiiieyanus, Morse. 



Shell umbilicated, subglobose, transparent, almost colorless, shining, 

 ^if'. 174. smooth, with microscopic wrinkles of growth and 



(f\\ /%> ^^^^^ more delicate oblique wrinkles; spire not much 

 & ^^^ziSX^ J elevated; whorls about 4, rounded, gradually en- 

 z. Binneyamm. largiug, the last globosc, broadlv umbilicated below; 

 aperture oblique, subcircular, large ; peristome simple, acute, extrem- 

 ities not approaching, that of the columella subreflected. Greatest di- 

 ameter, 4""° ; height, 2°''".

 Helix Binneyana, Morse, Amer. Nat., i, 542, fig. 32 (1867). 

 Zonites Binneyanus, W. G. Binney, Terr. Moll., v, 123. 



Southern part of Maine; Tawas Bay, Michigan; Massachusetts; 

 Vermont. It may be considered peculiar to the jSTorthern Eegion. 



Jaw very broad, arched, ends attenuated, bluntly rounded; concave 

 margin with a small, rounded median projection, on either side of which 

 are two smaller projections. (Morse.) 



Lingual membrane described by Morse with GO rows of 23-1-23 

 teeth ; centrals tricuspid ; laterals 2, bicuspid, but with a third cusp- 

 like process on the inner side; marginals aculeate. In Terr. Moll., Y, 

 Plate III, Fig. I, I give a figure of the teeth on a membrane examined 

 by me, kindly furnished by Mr. Anson Allen, of Orono, Me. I find 

 19-1-19 teeth, with 3 laterals. I doubt there beiug any inner cutting 

 points to the lateral teeth, as observed by Mr. ]\lorse on the lingual 

 examined by him. 



In Am. Journ. Conch., 1, 188, Mr. Tryon proposes for this species the 

 name Morsei, on account of the name Helix Binneyana being preoccu- 

 pied by Pfeifler. 1 have retained Morse's name, as it is not preoccu- 

 pied in the genus Zonites. In his first Catalogue of Maine Shells, Mr.
