54 THE NAUTILUS. 



Danvers lies back of Salem and Beverly at the headwaters of a 

 branching bay. A few days ago I made a trip to Plum Island. 

 Leaving the train at Rowley, I found P. salsa in a small ditch close 

 to the railroad station. A half-mile further down Litorinella minuta 

 was abundant in closed pot holes, but P. salsa not there. I do not 

 recall finding the two in company, yet they are often near neighbors. 

 We now have a distribution of this species from the New Haven area 

 in Conn., to Rowley, Mass., just north of Cape Ann, and very near 

 the New Hampshire line. 



A NEW C(ECUM. 



BY REV. HENRY W. WINKLEY. 



Caecum Johnsoni n. sp. 



Shell minute, tusk-shaped, slightly tapering, lightly curved. 2^ 

 mm. in length, ^ to f of a millimeter in diameter. Apex plug pro- 

 trudes in a dome shape. Aperture circular, end of the tube at the 

 apex is at right angles to the longer axis of the cylinder. Aperture 

 end at an angle, sloping towards the convex side, color dull white to 

 horn color, surface marked by lines of growth, but not ribbed. 



Dredged at Woods Hole, Mass., on gravel bottom in 2 to 3 

 fathoms. Easily mistaken for C. pulchellum. In size, color and form 

 it resembles that species but lacks the ribs, and the dome-shaped plug 

 in the apex is not seen in pulchellum. Types in Winkley collection. 



It gives me much pleasure to name this shell for one who has 

 shown himself a lover of the science, and a friend to his fellow- 

 workers, Mr. C. W. Johnson, of the Boston Society of Natural 

 History. 



A SMALL ADDITION TO THE KNOWLEDGE OF THE DANISH 

 MOLLUSCAN FAUNA. 



BY HANS SCHLESCH, COPENHAGEN. 



About 15 miles north of Copenhagen on the beautiful coast of the 

 Sound stands the pretty village of Rungsted, where many well-to-do 

 people from Copenhagen have their summer villas. Between 

 Rungsted and Horsholm (German Hirschholm) and a mile to the
