AmericaTi Journal of Science, vol. xxxv, p. 36, 1863. 



In this species, according to Minor, there are three pairs of ventral 

 fascicles of setse before the dorsal ones commence ; the i)harynx extends 

 to the fourth pair of ventral fascicles, from which a narrow oesophagus 

 extends to a little back of the sixth pair ; here a gradual enlargement 

 of the alimentary canal occurs, ending abruptly just back of the eighth 

 in a narrow, twisted tube, and this gradually enlarges at the ninth ven- 

 tral fascicle into a moderate sized alimentary canal. IsTo eyes. Length, 

 about 10™"\

 discovered.
