SOMATIC CESTODE INFECTIONS. 



No human infections with larval cestodes have been found. Strong, 11 

 reports two human infections with larval Echinococcus and upon inquiry 

 we have learned of two or three cases of cysticercosis and of at least one 

 other of echinococcus infection occurring in Manila within a few years. 

 These verbal reports are all more or less indefinite and no specimens 

 appear to have been preserved. 



Two specimens of pork infected Avith Cysticercus cellulosce have been 

 received and this parasite appears to be rather common among the native 

 hogs. The collection of the Bureau of Science also contains two speci- 

 mens of adult Echinococcus 12 obtained from native dogs. 



Taenia philippina sp. nov. 



Specific diagnosis. — Tcenia {Tamiarhynchus) : Strobila 80 to 100 centimeters 

 in length; 1 centimeter in maximum breadth; composed of about 800 proglottides. 

 Head cuboid, 1 to 1.5 millimeters in diameter: suckers 0.35 by 0.40 millimeter; 

 their lumena cylindrical to conical, directed forward and outward, 0.22 to 0.26 

 millimeter deep by 0.19 to 0.21 millimeter broad at their bases. Neck segmented, 

 its minimum transverse diameter, 0.70 millimeter, at about the 75th segment and 

 about 3 millimeters from posterior border of head. Sexual maturity first present 

 at from 15 to 18 centimeters from anterior extremity and in about the 470th 

 segment. Sexually mature proglottides 4 to 5 millimeters transversely by 0.8 

 to 1 millimeter longitudinally by from 1 to 1.3 millimeters dorso-ventrally ; 

 genital pore very slightly posterior to middle of lateral margin; cloaca 0.32 milli- 

 meter deep; cirrus distinct, 0.1 millimeter long by 0.03 millimeter broad; cirrus 

 pouch 0.38 millimeter long by 0.10 millimeter broad; vas deferens forms loop 

 within cirrus pouch, is without vesicula seminalis, and ends i:i a dilated 

 extremity before reaching median line; testicles 0.13 to 0.10 millimeter long by 

 0.06 to 0.08 millimeter in their transverse diameters ; vagina without sets and 

 forms two spiral coils between cloaca and excretory canal ; vitellogen gland 

 greatly elongated transversely, lies close against transverse canal, filling posterior 

 one-tenth of medullary space in median line, its extremities attenuated and ex- 

 tending laterally two-thirds the distance from median line to excretory canals; 

 ovaries composed of two unequal, transversely elongated lobes which lie close 

 against the vitellogen gland posteriorly and extend laterally through three-fourths 

 the distance from median line to excretory canals ; the smaller lobe, proximal 

 to pore of segment, is bounded internally by the median line and anteriorly by 

 the vagina ; the larger, distal lobe extends anteriorly to transverse plane passed 

 through genital pore, its anterior third projecting across the median line, 

 overlapping anteriorly the median extremity of the opposite lobe and filling the 

 space between the two limbs of the posterior V-shaped portion of the uterus ; 

 the uterine stem presents a V-shaped course in the posterior half of the 

 segment with its apex to the pore side of segment, its posterior extremity lying
