found to be the same as that in O. cochleotreina^ as it would be 

 unusual to find such marked differences in two species so closely 

 related.

Generio diagnosis. — Opisthotrematidae : Entire margin of body, 

 except space occupied by oral sucker, provided with a muscular rim. 

 Cuticle without spines. Oral sucker ventral, near anterior margin

 system ( ?), probably similar to that in O pisthotrema. Testes entire, 

 intercecal, situated near ends of ceca. Ovary median. Other charac-

Desc7'iption. — Pulmonicola': Body oval in outline, 5.13 mm long 

 by 3.95 mm wide; margin of body, except for the portion occupied 

 by the oral sucker, modified to form a muscular rim. Oral sucker 

 situated on ventral surface, 330/i, from the anterior margin ; esopha- 

 gus very slender, 180/a long by 28/[a wide; intestinal ceca uniform in 

 diameter and extending into the posterior fourth of body. Cirrus 

 pouch slender, spirally coiled distally, and containing a greatly con- 

 voluted seminal vesicle. Testes oval, entire, 390/i, long by 280yii wide, 

 situated intercecally in the same transverse plane. Ovary small, 

 median in position, situated a short distance caudad of the equator

 ately caudad of it ; receptaculum seminis present ; Laurer's canal pres- 

 ent. Vitellaria in intercecal field and consisting of a few isolated 

 follicles situated between the ovary and testes. Uterus slender, inter- 

 cecal, occupying the equatorial third of body in immature specimens, 

 but in mature specimens more convoluted and occupying the second 

 and third fourths of the b(jdy ; vagina dorsal to cirrus pouch; genital 

 pore at posterior end of body. Eggs 16|u. long by 9jii wide, yellow in
