Probably inhabits every State east of the Rocky Mountains; thus belongs to the Eastern Province. Animal black ; eye-peduncles long and slender ; tentacles conical and promi- nent. Respiratory orifice very visible at the angle formed by the junction of the peristome with the body whorl. The normal number of teeth, or that number which is most commonly ob- served in adult individuals, is certainly 4 ; but, in addition to those described, there is sometimes a small tubercle, or diminutive tooth, very near the junction of the peristome and body whorl, and more rarely another of the same descrip- tion, at the base of the aperture, near the umbilical tooth. If those only are to be considered fully mature which possess all the teeth, then the species may be characterized as having 6 teeth in the aperture ; but as one of them is nearly always, and another generally, wanting, the description here given is correct. The margin of the peristome is sometimes continuous entirely around the aperture. Fig. Pupa Please note that these images are ex
