9. Dislomum monticellii Linton. [Fig. 158.] 



1901. — Aug. 10, a single immature appendiculate distome from intestine. Dimensions, compressed, 

 in millimeters: Length 1.82; breadth 0.81; diameter of oral sucker 0.22, of pharynx 0.15, of ventral 

 sucker 0.39. Color yellowish, intestine very voluminous; pharynx conical, the larger anterior end 

 contiguous with the oral sucker. 



1902.— July 14, 1. This specimen is immature. The reproductive organs arc rudimentary, the 

 intestines voluminous. In front of the ventral sucker and just behind it the excretory vessel is filled 

 with o range-colored spherical concretions. Dimensions of living specimen in millimeters: Length 

 1.17; breadth 0.35; oral sucker, length 0.09, breadth 0.10; pharynx, length 0.054, breadth 0.050; 

 ventral sucker, length 0.22, breadth 0.24. 



10. Dislomum t, rme Linton. 



1901. — Aug. 12, 1, probably a young specimen of this species. Spines on the ventral surface, low, 

 flat, and rounded, those on the margins of the neck relatively long. The marginal spines disappear 

 about the posterior third. The ventral spines in the oral circles are very small ami slender, while, the 

 dorsal spines are stout. In this particular the specimen exhibits considerable variation from the 

 typical form of this species. Dimensions in millimeters, specimen compressed: Length 1.68; breadth 

 0.5; diameter of oral sucker 0.14, of ventral sucker 0.25; pharynx, length 0.21, breadth 0.17. 



1902.— Julv 17, 1. This specimen agrees with this species, except that the spines are missing.
