two long, curved, striated spines. The terminal joints are com- 

 paratively long and clawlike. The coxal joints are large. The 

 first three are short and broad, the length being a little less than 

 two thirds the breadth. They have narrow, curved, postlateral 

 prolongations equal in length to the second joint. The lower, 

 inner angles are rounded and crenulated. The dentate faces at 

 the inner, upper angles are on slight prolongations, which grow 

 longer with each succeeding coxa. All three begin with two 

 or three isolated, anteriorly directed, lobelike teeth, followed 

 by slender conic ones, which become finer toward the posterior 

 end. The fourth coxal joint is comparatively long. The inner 

 lower angle is gently rounded away, and the neck supporting the 

 narrow dentate face, long. The teeth appear to be compara- 

 tively few and coarse. The epicoxite of the third left coxa is 

 shown on plate 16, figure 1. 



The swimming arms are stout and moderately long, extend- 

 ing back nearly to the fifth tergite, and consist of nine joints. 

 The gnathobases are subquadrate and large, and are provided 

 with seven or eight short, bevel-edged denticles, the two anter- 

 ior being large and prominent. The length of the gnathobase 

 [see pi. 15, fig. 1] was 33 mm, its breadth 30 mm, the length 

 of the dentate face 8 mm. The middle joints have the anterior 

 and posterior angles sharp, in the fifth the anterior forming 

 a blunt, striated spine, much like those at the sides of the 

 postabdomen. The seventh and eighth joints are broadly 

 expanded, and their margins, particularly in the latter, are 

 marked by sparse, shallow serrations. Inserted on the inner 

 side and near the end of the eighth joint, is a small, oval, rudi- 

 mentary ninth joint. 



The metastoma is elongate ovate, widest in the middle, with 

 ends truncated. The anterior or narrower end is notched and 

 minutely dentate. 



The genital appendages of this species, so far as they are pre- 

 served in the material of the collection, are, with the exception of 

 the part carried by the second sternite in the female, essentially 

 like those of E. fischeri Eichw., as described by Holm (13). 

 That of the female is the more complex and is carried partly by
