abdominal ganglion. 
3. The bi-ain is complicated, but few long tracts of fibers are 
e\iilent. 
4. There may be areas which may represent anterior and poste- 
rior pairs of globuli of spiders and scorpions, but if so they do not 
ha\e the same structure. 
5. There are no trachea in the central ner\ous system. 
6. The cells are uniform except for a mass each side of the 
brain in a cephalic dorsal position.
