Beringius stimpsoni Gould, 1860 
Plate 21, fig. 2 
Proceedings of the Boston Society of Natural History, 7 :325. 
Testa magna, solidula, elongata, fusiformi-turrita, cinerea vel dilute 
ferruginea, epidermide calcarea caduca incrustata, lines tenuibus cincta; 
anfr. 6 ad 8 pyramidatis, pentagonalibus, ultimo antice excavato, costa 
cincto ubi undae terminantur. Apertura dimidiam longitudinis testae 
adaequans, anguste lunata; labro simplici; columella arcuata, callosa; fauce 
dilute castanea vel livida. Long., 100; diameter, 45 mm. (Gould.) 
A quite remarkable species, allied to B. undatum, but at once dis¬ 
tinguished by its elongated form, and its pyramidal, pentagonal whorls 
with concave sides. (Remarks by Gould.) 
Type in United States National Museum. Type locality, Arikamcheche 
Island, Bering Straits.

Described as Buccmum stimpsoni. 
Beringius malleatus Dali, 1884 
Plate 22, fig. 5 
Proceedings of the United States National Museum, 7 :525. 
Shell long and slender, the young shell forming several whorls in an 
almost cylindrical coil before they begin to enlarge. The adult shell may 
reach 6 inches in length. The surface is covered with fine spiral striae 
and a thin brown epidermis. The nucleus is large and blunt, the canal 
short, the form of the mouth variable in different stages and specimens; 
the outer lip is thin, the aperture dark purple within; the last whorl less 
than half the length of the shell in most cases. It is generally rude and 
more or less worn, even when living, the cylindrical tip usually broken off, 
but the polygonal horizontal section of the whorls is very characteristic.

Beringius frielei Dali, 1894 
Proceedings of the United States National Museum, 17 :711; PI. 27, fig. 8. 
Shell resembling B. turtoni in size, but with a more regularly tapered 
spire and deeper suture; the epidermis of a redder brown and not polished ; 
very adherent; the sculpture is of close-set pairs of flattened spiral threads, 
each pair separated by a sharp channeled groove, as wide as a thread,
