ART. 3. NEW TREMATODES FROM AMPHIUMA MEANS CHANDLER. 3 



Galium 1921 differs in so many features of its anatomy from other 

 members of the genus that it should undoubtedly be placed in a new 

 genus, and two others, G. retusus (Dujardin) and C. europaeus 

 Blaizot 1910, from Bona esculenta in Europe, are probably identical. 

 The type species, G. lenoiri, was described by Poirier from a turtle, 

 Tetrathyra vaillantii, from Senegal. Two American species have 

 heretofore been described, one, G. americanus, by Stafford (1902) 

 from the intestine of Eana virescens and R. clamitans in Canada, 

 the other, C. vesicaudits, by Nickerson (1912) from the intestines of 

 soft-shelled turtles, Aspidonectes and Amyda, in Minnesota. Both 

 G. americanus and G. vesicaudus differ from the type species and from 

 G. restusus in having the testes arranged in an oblique manner in- 

 stead of one directly behind the other ; G. amphiumae agrees with the 

 type species in this respect. The ovary of G. amphiumce is situated 

 much nearer the median line of the body than that of any of the other 

 species. This species also differs from all the others in the more an- 

 terior position of the acetabulum and genital glands, and in the fact 

 that the vitellaria do not extend forward beyond the anterior margin 

 of the acetabulum. In addition to these differences it is of larger 

 size than any of the other described species, and has a relatively 

 larger pharynx. It resembles G. ame7'icanus in having the oral 

 sucker a little larger than the acetabulum, but differs in having the 

 genital opening situated on an anterior papilla instead of being at 

 some distance from the anterior end, on the dorsel side. The very 

 short, almost negligible esophagus is intermediate between the con- 

 dition found in G. lenoiri, G. retusus, and G. americanus on the one 

 hand, and G. vesicaudus on the other.

Plate 1, fig. 2. 



Diagnosis. — Body 4 to 5 mm. in length, with maximum width of 

 0.58 to 0.64 mm. Sides nearly parallel, but the body tapers slightly 

 in its posterior half, both ends bluntly rounded. Cuticle spiny 

 anteriorly to about level of ventral sucker. Oral sucker about 0.215 

 mm. in diameter. Ventral sucker, at junction of first and second 

 fourths of body, relatively very large, 0.356 to 0.288 mm. in diameter. 

 Pharynx, preceded by a short prepharynx, also large, 0.096 to 0.106 

 mm. in diameter. Esophagus variable, 0.17 to 0.23 mm. in length. 

 Intestinal ceca reach almost to posterior end of body. 



Ovary spherical, 0.17 mm. in diameter, at junction of third and 

 fourth sevenths of body length, with shell gland and ootype immedi- 

 ately behind it. Descending and ascending uterine coils to left and 

 right sides, respectively, but overlapping considerably; metraterni 

 broad, almost straight, extending about two-fifths of distance from
