The specimen agrees in so many points with 

 Boeck's description and figures that the determina- 

 tion is not very doubtful. Nevertheless it must be 

 mentioned that the upper lip is a little excavate 

 apically, whereas Boeck states that the upper lip is 

 apically rounded, in the characters which he gives 

 both for the family and the subfamily in Avhich he 

 places Protoviedeia. Moreover, the fifth joint in the 

 lower antennae is longer than the fourth, and the 

 flagellum is longer instead of shorter than the fifth 

 joint of the peduncle. The outer branch of the 

 third uropods is shorter than the inner, which 

 agrees with Boeck's figure of the species, though it 

 differs from the chai*acter of the genus. The apical 

 margin of the telson is concave, whereas in Boeck's 

 figure it is convex ; but as he does not describe the 

 telson, he had perhaps not been in a position to 

 observe it accurately. 



Whether this and the following species should be 

 transferred to the genus Ptilocheiriis, Stimpson, or
