mentum is large and of a semicircular shape, deeply emarginated, 

 which renders the lobes heavy, rounded outside, and pointed at 

 the tip. In the bottom of this emargination stands a pointed, 

 spine-like tooth, as long as the lobes. This tooth is deeply 

 excavated or grooved, and is clearly seen to be to its full length 

 soldered together with the basal part of the ligula; probably 

 the entire mentum is in this manner connected with the adjoin- 

 ing part of the ligula, but in the other parts it is not so clearly 

 observable as in the tooth, and I have not dissected the labium. 

 The ligula itself is of a leathery consistence, of the shape of an 

 elongated inverted triangle with an elevated back ; the anterior 

 margin is straight, and somewhat prolonged beyond what would 

 be the sides of the triangle. The paraglossse are of membrana- 

 ceous texture, very broad, adhering to the sides of the ligula to 

 its full length, taking then a slender cylindric form, and reach- 

 ing considerably beyond it, being at the same time slightly bent 

 inwards.
