Genus AMPHILOCHUS. 



Amphiloclius. SPENCE BATE, Cat. Amph. Brit. Mus. p. 107. 



Generic character. Cephalon anteriorly produced. Eyes two. 

 Superior antennae without a secondary appendage. Gnathopoda 

 subchelate, each having the carpus infero-anteriorly produced. 



THE head in this genus is produced considerably in 

 advance, and curved downwards. The eyes are two dis- 

 tinct organs, and are situated in their normal position, 

 between the superior and inferior antennas. The su- 

 perior antennae are tolerably robust, somewhat longer 

 than the inferior pair, and not furnished with a secondary 

 appendage. The inferior antennae are more slender than 

 the superior. The arms are furnished with subchelate 

 hands, but those of the second pair are larger than those 

 of the first pair : both are, however, remarkable for the 

 extension of the infero-anterior angle of the wrist. In 

 this they approximate to the genus Monoculodes, but the 

 form of the eyes appears to warrant their generic separa- 

 tion. The recent discovery, however, of a species of 

 Kroyera, which differs from the type of the genus in 

 little else than in the character of these organs, induces 

 us to believe it possible that future research in this 



JL 



branch of natural history may establish a closer alliance 

 between Amphilochus and Monoculodes.
