Found in ponds and ditchesabout New Orleans, in Florida, Georgia, and South Caro-lina. They are capable of living on dry land, but howlong, has not been accurately ascertained.

The smallest was veryinteresting, as it was but three inches in length, and yetdid not exhibit the least appearance of branchiae. Totallength of the largest was two feet two inches ; breadth ofthe head across the eyes eleven-tenths of an inch: dis-tance between the eyes seven-tenths; between the nos-trils three-tenths; from the eyes to the tip of the snoutseven-tenths ; distance between the anterior and posteriorextremities twelve inches and three tenths. Vent, a dis-tinct longitudinal rima, situated immediately behind theposterior extremities. From the vent to the extremity ofthe tail six inches and three tenths; tail tapering andcompressed at the lower half. Girth four inches and two-tenths ; length of the posterior extremity six-tenths: ofthe anterior, four-tenths, perhaps somewhat contractedby spirits.
