pointing from its apex to the juncture of rostrum and carina. Along 
the margin adjacent to the fixed tergum an almost equally prom¬ 
inent ridge is developed, and between this ridge and the diagonal 
crista two narrower ridges are found; the four ridges mentioned 
interlock with ridges of the carina. Above the diagonal crista three 
or four ridges interlock with as many ridges of the scutum. The

interior side of the plate is somewhat exeavated, but otherwise 
without sculpturation like the movable scutum. 
The movable scutum interlocks with the tergum by three 
or four ridges, and with the rostrum by four regularly developed 
strong ridges. 
The line between the apices of carina and rostrum in the larger 
specimens measures 4,5 mm, the line from the rostral apex to that 
of the fixed tergum 5 mm; height of the carina 2 mm. 
Of the mouth parts the m a n di b 1 e (Fig. 44) has three teeth, 
the second placed in the middle of the cutting edge. The lower 
angle is pointed, its anterior side armed with about six long and 
siender denticles. The lower half of the mandible is covered with 
small, fine hairs. 
The max i 11a has a strong upper spine and below this two 
more siender and somewhat shorter spines above the great excav- 
ation which occupies about half the cutting edge. No shorter spines 
or thorns are present in the exeavation. Below the latter the cut¬ 
ting edge is armed with five or six siender spines. The outer part 
of the maxilla is hairy. 
In cirrus I and II the anterior ramus is mueh shorter than
