FLUDA N. 



Cephalothorax moderately high, about twice as long as 

 wide, sides parallel in cephalic part, narrowing a little behind. 

 Cephalic part inclined forward. Beyond the dorsal ej^es is a 

 depression, and back of this the thoracic part rises into a ridge 

 and then falls quite abruptly. Quadrangle of eyes one-fourth 

 wider than long, wider in front than behind, occupyiug one- 

 half of the cephalothorax. Anterior ej'es in a straight row. 

 Second row about half-way between first and third rows. Third 

 row as wide as cephalothorax at that place. Lip wider than 

 long. 



Fluda differs from Erica and Keyserlingella, genera 

 which are nearly related, and are found in the same locality, 

 in the shape of the cephalothorax. Keyserlingella is much 

 flatter and has no depression, while Erica has the thoracic 

 part rounded behind the depression, without any abrupt slope. 

 Keyserlingella also differs from Fluda in having the quad- 

 rangle of the eyes equally wide in front and behind, or wider 

 behind, while in Fluda it is wider in front.
