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

 fourteen indistinet 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 sei-rated 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 

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