Krauss, in describing Nacrophthalmus boscii, Audouin, refers 

 it to Savigny's pi. 2, fig. 1, and states that the usual fulness of 

 detail supplied by Saviguy is on this occasion wanting. Miers 

 in the Crustacea of the " Alert " and in his " Challenger " report 

 gives the same reference, while following A. Milue-EdAvards in 

 assigning the species geiierically to Euplax ( Chtenost oma) , but 

 the authors are evidently alluding to fig. 2 of Savigny's plate. 

 His fig. 1 has the accustomed amplitude of finely drawn details, 

 which excellently correspond with those of a specimen from 

 South Africa. 



Our specimen has a carapace about 8 mm. long by 10 mm. 

 broad, the rostrum deflexed, lightly bifid, the orbits oblique, the 

 lateral borders setose. The pleon of the female is as figured by 

 <le Haan, the seventh segment broad, though not very long. 



The chai-acteristic mouth-organs are well shown on Savigny's 

 plate, unless the length of the maudibular palp is exaggerated, 

 for in our example that feature is only normal. Both pairs of 

 maxillae have their laminae well developed and powerfully 

 setose. In the first maxillipeds the principal joint of the endo- 

 pod is elongate with parallel sides and rounded apex. The third 

 maxillipeds have the fourth joint as long as the broad third 

 joint, and even broader by the bulging of its convex outer 

 margin ; the epipod is more elongate than that shown in 

 Savigny's figure. The right cheliped of the female is missing, 

 the left is in accord with Savigny's figure.
