Of the head itself no definite structure can be ascer- 

 tained, but projecting in front of it there are indications 

 of an appendage which, in length and position, would cor- 

 respond with the lower antenna, although it is too indistinct 

 to show any details, except perhaps two or three segments 

 of the multi-articulate flagellum. 



The peraeon segments are very indistinct, but they are 

 apparently all present; and, in the second, the inferior 

 margin, projecting anteriorly into a subacute point, can be 

 made out, with below it apparently the epimeron or coxal 

 joint of the peraeopod.
