 pereion, with the eyes very wide apart, fixed on thick peduncles. Upper 

 antennje with four very short basal joints, followed by a very long slender 

 one, terminated in a short triai-ticulate flagellum, and two long auditory cilia.

 strong teeth at each side. 



Length, rather more than half a line. 



The head is very large and broad, increasing in width 

 posteriorly, equal in length to the three following seg- 

 ments ; the eyes are fixed on very thick and prominent 

 peduncles. The front of the head is nearly truncated, 

 and the upper antennae are affixed widely apart next 

 the anterior-lateral angles of the head. The peduncle 

 consists of four very small joints, of which the first is 

 most robust, and a fifth, that is very long and slender.
