A series collected by Steere at Magdalena, Peru, shows great 

 variation, and indicates that varians, rube/his and tigris are color- 

 forms of vexillum. Some specimens have six wide or narrow con- 

 tinuous blackish bands ; in others the upper four bands are inter- 

 rupted to squarish spots. Still others show various transitions to D. 

 tigris, of which B. keppelli Pfr. (vol. xi, p. 296) seems to be merely 

 a variety. D. vexillum, D. tigris and D. keppelli have been sent 

 from the Rio Yonan, from Fulton. Specimens of keppelli are 

 figured (pi. 26, figs. 36, 37). 



D. INTERPUNCTUS (Martens). Vol. xi, p. 287. 



Evidently of wide distribution in prov. Sao Paulo, Brazil. Dr. 

 von Ihering sends specimens from Piquete.

The locality " San Nicolas, central Nicaragua (Tate) " should be 

 deleted. Tate's shells, ?ome of which are before me, are D. domi- 

 nicus.
