not fully identical with tliis type, it woiilcl perliaps be con- 

 venient to piit it down as a variety of Aega magnifica Dana. 

 In any case it seems fit to give here a sliort acconnt of its 

 characteristical points.

 Fl. II. tig. 11—17. 



The form of the bodt/ is elongate-ovate, nearly thrice as 

 long as broad (71 : 26). According to Dana's specimen tbe 

 animal is qiiite thrice as long as broad (28 : 9), according to 

 the specimens of Schioedte and Meinert it is only a little more 

 than twice as long as broad (74 : 33). 



The head is as long as the first segment of the pereion. 

 The middle part of the front scparates half of the basal joints 

 of the vipper antennae. 



The eyes are large, distant by a third of the breadth of 

 the head. They are nearly rectangnlar, the hinder margin 

 being feebly ronnded, with the ocelli arranged in seven rows, 

 15 in each. 



The third joint of the pedvmcle of the first pair of 

 anteniifP is the lougest. The flagellum, ten-jointed, reaches 

 beyond the anterior margin of the first segment. 



The flagellum of the second pair of antennce is 19-jointed; 

 it reaches beyond half of the second pereional segment. (Pl. II 

 tig. 13). 



The fifth and sixth segments of the j^^reion are the long- 

 est, equal, much longer than the first (4 : 3) (in Dana's spe- 

 cimen the first sixth and seventh segments are equal, the fifth 

 much shorter). The fifth, sixth, and seventh segments being 

 deeper than the preceding, the row of epimerals is not even 

 (Pl. II. fig. 12). On each of the epimerals of the second to 

 fifth segments there is an oblique line. The two last epime- 

 rals have two such lines. The last epimeral does not reach 

 half-way of the first pleonal segment. The femora of the three 

 first pairs of pereiopoda (Pl. II. fig. 14) are smooth, without 

 bristles or spines ; the tibias are provided with five to six very 

 short, obtuse, stout spines. The metacarpi throw out each a 

 broad hatchet-like process, the edge of the process equalling 

 the metacarpus in length. 



The pleon equals in length the head and the first pereional 

 segment. It is quite free, the first segment not at all covered
