THAUMATOPSID^E. 



ramus, dilated, the outer margin with about twelve low teeth, the anterior margin with 

 fourteen indistinct teeth, and the inner margin with thirteen larger, unequal teeth; the 

 outer ramus is similar in shape to that of the first pair, smooth, somewhat shorter than 

 the inner, and a little shorter than the breadth of the peduncle; the inner ramus is four 

 times as broad as the outer, minutely serrated along the outer and anterior margins, and 

 coarsely serrated along the inner margin. The uropoda contain large glands. The length 

 of the first pair of uropoda is 18 mm., of the second pair 14; the breadth of the peduncle 

 of the last pair is 5 mm., the length of the outer ramus of the same pair is 4,5 mm. 



The telson is very small, scarcely more broad than long, about as broad as a third 

 of the breadth of the peduncle of the last pair of uropoda.
