Genus— AMPHILOCHUS. 
Amphilochus. Spence Bate, Cat. Amph. Brit. Mus. p. 107. 
Generic character. Ceplialon 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 antennae. 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 , wdiich 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 
branch of natural history may establish a closer alliance 
between Amphilochus and Monoculodes.
