The supraesophageal ganglion is of rather small size. It 

 sends small nerves to the eyes, to the first pair of appendages 

 or chelifori and a mid-ventral branch to the proboscis. 



The subesophageal ganglion supplies the other cephalic 

 appendages. There are three branches from each side of this 

 ganglion, one pair is for the proboscis, one for the palpi, or 

 second appendages, and one pair for the ovigers, or third 

 appendages. The second and third appendages are spoken of 

 by some authors as being supplied by distinct ganglia. In this 

 species there is no division into two centers. 



The chief branches of all of the other ganglia are to the 

 four larger appendages, or walking legs.
