Fig. 20. — Teeth of Bezoardica. 



The lingual band of Bezoardica ? narrow, elongate, trans- 

 parent, "brown at the end. Teeth 3 ■ 1 ' 3, the central rather narrow, 

 transverse, upper edge marked with seven or nine elongated acute 

 denticles, the central longest, the rest gradually shorter ; the inner 

 lateral tooth broad, transverse, strongly denticulated on the inner 

 side of the upper edge ; the two outer lateral elongate, subulate, 

 versatile, curved for half their length ; the inner pair rather shorter, 

 with three or four denticulations on the inner side near the tip ; the 

 outer pair rather longer, and entire at the tip. The outer lateral 

 teeth fold over together, and prove to be two series, as there are 

 two opposite the end of each internal lateral tooth. The teeth are 

 most like those of Trichotropis bicarinata, but the central and inner 

 lateral teeth are denticulated (fig. 20) . 



The teeth of Bezoardica glauca 3 • 1 ■ 3 ; central broad, with 

 many equal denticulations ; the inner ? (outer ?) lateral broad, tri- 

 angular, with many denticulations on the sloping edge ; the outer 

 (inner ?) elongate, narrow, with three long acute denticulations at the 

 tip. — March.
