 Alonogr. viii, p. 147. 



Described from a single imperfect specimen, which has very deli- 

 cate, scarcely raised, very smooth plicae, like the related Peruvian 

 species, and white spots here and there interrupt the streaks. The 

 embryonic whorls are smooth and corneous. It has not been figured 

 or recognized by subsequent writers. 



D. VEXILLUM (Wood). PI. 26, figs. 34, 35. 



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

 variation, and indicates that variant, rubellus and tiyris 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 Yonnn, 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. 



D. SEMIMACULATUS Pils. Vol. xi, p. 297. 



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

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

 nie us.
