One of the specimens that might be said to constitute the 

 excavatiis series is unquestionably the recent form. It proves the im- 

 practicability of drawing closely delimited division lines, where specific 

 characters so closely approach one another, and demonstrates the nec- 

 essarily arbitrary classification which the evidences of transformism must 

 carry with them. 



Fulgnr .pyrifonnis, Conr. 



I have been unable to find a description of this species, and only 

 know it from a specimen in the Academy's collection marked such in 

 Conrad's handwriting. It is identical with the scalariform varieties (so 

 considered) of K pyrum (F. plagosus of Conrad?), which in several char- 

 acters depart widely from the typical forms of that species, and might, 

 perhaps, with propriety be considered distinct. It stands intermediately 

 between F. excavatus and pymm, 



Banks of the Caloosahatchie below Fort Thompson. 



Tnrbinella regina, nov. sp. Fig. 5. 



Shell ovate-oblong, sub-fusiform ; spire elevated, gradually tapering, 

 and consisting of from eight to ten volutions ; whorls nearly flat, or 

 slightly convex, somewhat angulated above, and only nodulose in the 

 region of the apex ; surface covered with revolving raised lines, about 

 five on each whorl below the upper angulation, above which they are less 

 pronounced and more closely placed. 



Body-whorl convex, considerably longer than one-half the length of 

 the shell, and ornamented by numerous raised lines, similar to those 

 found on the other whorls. Toward the base these lines become more 

 crowded, somewhat flexuous and coarse, appearing in the form of paired 

 rugations; suture impressed; aperture elliptical, produced into a 

 straight, but deflected, canal of considerable length. 



Columellar surface covered with a thick deposit of callus, which 

 leaves partially uncovered a long and narrow umbilicus; columdlar 

 plaits three, the median one of which is the strongest. 



Length of longest specimen imperfect below and above, and lacking 

 probably an inch and a half eleven inches; width across the centre, four 

 inches. 



Caloosahatchie, in the banks below Fort Thompson. 



We found but two specimens of this stately Turbinella, which in 

 linear measure surpasses all other species of the genus, with the excep- 

 tion of T.scolymus. In its general characters it most approximate* among 

 recent forms Turbinella ovoidea of Kiener (Icon. Coq. Viv., 7), which is
