A NEW KOENENJA FROM TEXAS. 221 



in a somewhat irregular row on and near the edge of the 

 appendage. The paired triangular appendages of the third 

 segment, as usual, have three pairs of setpe — two long ones, 

 arising on the posterior surface or from underneath, when 

 viewed from the ventral surface, and a small one situated on 

 the side of each appendage. The blades of these appendages 

 are more pointed than the corresponding ones in K. 

 wheeleri. Shining through the unpaired portion, and open- 

 ing between the bases of the two paired ones of the repro- 

 ductive appendages, is seen the large seminal vesicle, which 

 is nearly oval in outline. This vesicle in K. wheeleri was 

 flask-shaped, with the neck of the flask projecting downward. 

 Figs. 6 and 7 of the plate show the true condition of these 

 appendages better than any amount of description. 



Flagellum. — When the material reached me through the 

 mail the flagellum had been broken oif in every case except 

 one. This was an adult female, which had only twelve joints 

 in the flagellum. However, I found floating around in the 

 alcohol in which the specimens were sent, one flagellum of 

 fifteen joints (counting the first small joint, which is never 

 detached with the flagellum, but always remains with the 

 body), another of fourteen joints, and another of twelve joints. 

 In all these cases none of the proximal joints had been broken 

 off except the small joint of Avliich I have made mention. In 

 these four flagella the second, third, fourth, sixth, eighth, and 

 tenth joints had two whorls of setae ; a plumulose Avhorl of 

 long setae running around the middle of the joint, and a 

 smooth terminal set which fitted closely over the subsequent 

 joint. Always following the joint bearing the double whorl 

 of setae which precede the segment-bearing whorl of hairs 

 are the very short, thick-walled sub-joints Avhich may be 

 looked upon as the anterior portion of the large joints, to 

 which they are immovably attached. The terminal joint in 

 two cases had two whorls of plumulose setae; in the other two 

 flagella it bore only one whorl. In every instance, except in 

 the number of joints, the flagellum carries out all the observa- 

 tions made on the corresponding appendage in K. wheeleri.
