Eine total verschollene und kaum jemals wieder mit Sicherheit zu erkennende 
Art. Tryon zieht sie mit grossem Zweifel zu cyaneum. 
71. Bucceinum Rodgersi Gould Otia p. 122. 
T. ovato-lanceolata, solidula, luteo-einerea, erusta eretacea sub epidermide tenuissima 
induta, striis exilissimis eineta; anfr. 8 tumidulis spiram elongatam nunc undulatam nune 
aequam efformantibus, ultimo trientes duos long. metiente, et in rostrum satis productum 
sensim contracto. Apertura ovata, dimidiam longitudinis testae haud aequans, labro evaso, 
postice sinuato; columella callo bene induta; fauce flavida vel livida. 
Long. 55, diam. 25 Mm. 
Inhab. Arimkakeche Island, Behrings Strait. 
Like B. undatum the varielies are very widely contrasted as to the undulatioa 
of the surface, and but for the uniformly siender growth and elongated beak might 
probably have been brought under that species. 
Anmerkung. Dall schreibt mir über diese Art: the type of B. Rodgersi is lost, 
but it was only a var. of glaciale.
