In many respects closely related to the foregoing, but vdih. 

 sharply defined differences. A stout, somewhat opaque worm. 

 Length 12-15 mm., • 5 mm. diameter, about 50-55 segments. 

 Coelomic corpuscles, large firm discoid bodies. Setae unequal, 

 Fridericia-\^k&, usually 4-7 in front of girdle, 3-5 behind. Brain 

 about as long as broad, slightly incised behind. Two pairs of

septals only in some cases (perhaps abnormal), the pair in front of 

 spermathecpe wanting. Salivaries present, also one pair of oesopha- 

 geal glands in 8. Dorsal vessel arises in 8/9, and intestine enlarges 

 in segment 9. Girdle opaque, including 1/3 or 1/2 of segment 11, 

 the whole of 12, and 1/2 13. Glandular cells of girdle very close-
