eral (apparently meaning on same transverse plane), divided into 2 large 
equal lobes with sinuous margins, thus giving the appearance of 4 testicles 
occupying the corners of a square. Uterus with numerous slings, crowded 
together, and crowded with eggs in different stages of development ; vitellaria 
lateral of intestinal ceca, with grapelike follicles ; vitelline canals unite in 
posterior part of body, above (cephalad? or dorsad? of) acetabulum in the open 
space; ovary and shell gland near median line. — Based on Giard and Billet, 
lS92a, 615. 
Habitat. — Attached to mucosa of large intestine of cattle Bos Uiurusf or B. 
taurus iridicusf at Tonkin. 
Giard and Billet do not describe the form of the body, but state 
that it is different from that of //. jyalonide. 
HOMALOGASTER PHILIPPINENSIS new species. 
(Figs. 29 to 44.) 
Specific diagnosis. — Homalogastcr (p. 23) ; Body 7.5 to 9 mm. long by 4.5 
to 5 mm. (or flattened to 7 mm.) broad, canoe shaped, cephalic extremity 
attenuated, caudal extremity rounded ; when flattened, sides very convex ; 
dorsum may show submedian longitudinal depressions. Genital pore 1 mm. 
trom oral margin (about one-ninth to one-seventh of body length from mouth, 
and about at equator of esophagus) surrounded by depressed circular area 
bearing numerous small papillae. Venter with alternating longitudinal rows 
of large papillae extending from about 2 or 2.5 mm. from oral margin to 
acetabulum. Margins curved ventrally and are fairly sharp. Acetabulum 
about 2.5 by 2.7 to 3 mm. Esophagus extends to about one-flfth of body 
length from oral margin ; intestinal ceca narrow, slightly tortuous, long, ex- 
tending to acetabulum. 
Male organs: Testicles lobate, in cephalic half of space between ceca; one 
caudad of the other;- vesicflla seminalis quite compactly coiled; pars mus- 
cularis distinctly but not highly developed; pars prostatica not prominent, 
may enlarge to quite a large diameter, thus resembling a “ vesicula seminalis 
interna;” ductus ejaculatorius present; cirrus absent. 
Female organs: Ovary and shell gland submedian, near end of one of the 
ceca, ovary cephalad of shell gland; vitellaria extend about from the bifurca- 
tion of esophagus to caudal plane of ovary ; uterus with many coils, well 
developed, passes cephalad, dorsally of testicles, ventrally between vasa effer- 
entia, ventrally of vas deferens, to pore; Laiirer's canal opens dorsomedian at 
plane of termination of ceca. Genital papilla, when extruded, resembles 
human penis' with glans ; bears on its vertex a pore, from which runs the 
short ductus hermaphroditicus ; when retracted the papilla resembles a par- 
tially inclosed cirrus pouch. Egg oval, operculaJ:ed, with small knob at 
opposite pole; 125 to 139/a by 67.5 to S6/t. 
Excretory ix)re dorsomedian about at equator of acetabulum. 
Habitat. — Cecum of Bos , at Manila, P. I. (type locality), and Phra- 
patoom, Siam. 
Type.— U. S. P. H. & M. H. S. 9580 (mounted) ; Cotypes 9581 and 9960. 
Source of material. — This species has been sent to ns on two oc- 
casions by Dr. Panl G. Woolley. The first specimens (U. S. P. H. 
& M. H. S. Nos. 9580 and 9581) were collected in 1904 from the cecum 
of two calves {Bos ) at Manila, P. I.; the second sending (U.
