THYSANOTE. 187 



Genus 38. THYSANOTE Kroyer, 1863. 



Syn. Brachiella Nordmann (in part). 



Cephalothorax short, robust ; genital segment short, 

 dilated, and somewhat flattened, the postero-lateral 

 corners each provided with two moderately short pro- 

 cesses of about equal length ; another pair of rather 

 longer submedian appendages springing from the 

 ventral aspect and a little in front of the posterior 

 margin. Abdomen obsolete or nearly so. 



Both pairs of antennas small and rudimentary. 

 Mandibles moderately elongated, and having the inner 

 margin near the distal end coarsely and irregularly 

 serrate. Maxillae and first maxillipeds somewhat 

 similar to those of Brachiella. Second maxillipeds 

 free, each with the extremity expanded and obscurely 

 trilobed, the tip of the inner lobe of each maxilliped 

 being apparently united together. 



Thysanote has a close general resemblance to Brachiella, 

 both in the form of the body and in the free second 

 maxillipeds ; the structure however of these maxillipeds 

 differs, and the genital segment also differs in being fur- 

 nished with two pairs of posterior appendages.
