Dermacentor americanus. As the carrier of Rocky 
Mountain spotted fever, this tick is of especial 
interest at present. 
Dr. Ransom presented some figures illustrating 
the life history of Habronema musce and showing 
stages in the fly and in the horse. A note on this 
life history has already been published in ScIENCE. 
Dr. Ransom presented the following note: 
The Occurrence of Cheilospirura hamulosa in the 
United States. 
The nematode Cheilospirura hamulosa is para- 
sitie in the gizzard of the chicken. A record of 
the occurrence of this species in the United States 
has apparently not been published heretofore. 
The helminthological collection of the Bureau of 
Animal Industry contains specimens collected in 
Kansas in 1897, identified by Stiles and Hassall; 
in New Jersey in 1903, identified by Ransom; in 
Hawaii in 1907, identified by Hall and Hassall; in 
the District of Columbia in 1908 and 1909, iden- 
tified by Hall; in Ohio in 1911, identified by Gray- 
bill, and in Indiana in 1911, identified by Ransom. 
Dr. Pfender presented the following note: 
Symptoms Accompanying an Infection with Tenia 
saginata. 
Recently one of the writer’s patients, a woman 
54 years old, presented herself for treatment and 
complained of the following symptoms: itching all 
over the body, skin eruptions, recent trouble with 
cold feet, twitching of lower limbs, nausea, no 
desire for food, excessive bloating, flatus, occa- 
sional dizziness and excessive leucorrhea. She 
complained that pieces of worm, from 3 to 30 at 
a time, were being constantly passed. On treat- 
ment with oleoresin of male fern the worm was 
passed. Since then the nervous and digestive 
symptoms have entirely disappeared and the gen- 
eral health is improving. 
THE eighth regular meeting of the society was 
held in the rooms of the Zoology Division of the 
Marine Hospital Service, January 11, 1912, Dr. 
Stiles acting as host and Mr. Foster as chairman. 
Dr. Garrison exhibited a specimen of pancreas 
sent in by Assistant Surgeon Kerr, U.S.N., from 
Guam. The pancreas had a specimen of Ascaris 
lumbricoides in the duct of Wirsung, extending 
from the intestinal termination of the duct clear 
across the pancreas, the head being near the 
periphery. He also showed two appendices, con- 
taining 2 and 3 specimens of the same worm, sent 
in by Dr. Kerr from the same place. 
Dr. Ransom presented pictures of a worm sent

in by Dr. Darling from the Canal Zone and said 
to have been collected from the urine of man. 
The worm is a specimen of Mononchus, a free- 
living genus, and the case is therefore one of 
pseudo-parasitism. The tooth in the buccal cap- 
sule would suggest a true parasite to most ob- 
servers. 
Dr. Ransom noted that numerous cases of Cys- 
ticercus bovis had recently been detected in abat- 
toir inspection, 15 cases having been found in two 
days at Omaha. The parasite has also been 
rather common at Chicago, Kansas City, Mil- 
waukee, Buffalo, etc. Up to a year ago, more 
specimens of Cysticercus cellulose had been found 
than of C. bovis, due probably to the fact that 
the former were more carefully looked for. 
Dr. Stiles noted that Dr. Francis had recently 
sent him several cases of C. cellulose from Texas 
with the statement that this parasite was not un- 
common in Texas. 
Dr. Stiles presented a note on the preliminary 
survey of Texas for hookworm. He spent one 
month there, working at the state university, the 
normal school and the schools for the blind and 
the deaf and dumb, and in the open country. He 
demonstrated hookworm by microscopic findings 
in 45 counties and saw undoubted physical cases 
in another county. The disease occurs chiefly in 
the eastern portion of the state, and is probably 
unimportant in the northwest portion. In the 
rural eastern part, some places show about one 
third of the people infected. There are some 
severe cases, but none as bad as the worst cases 
in Alabama and Mississippi. A preliminary sur- 
vey of the coal-mining part of West Virginia was 
interrupted after the hookworm had been micro- 
scopically determined in nine localities. 
The rest of the evening was devoted to a talk 
by Dr. Stiles on ‘‘Foreign Parasitologists and 
Their Work.’’ 
THE ninth regular meeting of the society was 
held in the rooms of the Zoology Division of the 
Marine Hospital Service, 25th and E Streets, 
N.W., February 16, 1912, the president, Dr. Stiles, 
acting as host and chairman. 
Dr. Stiles presented a number of generic names 
of parasites of man for consideration by the 
society. The society agreed to recommend to the 
International Committee on Nomenclature and to 
the Committee on Medical Zoology for adoption 
according to the plan agreed upon at the last 
Zoological Convention at Gratz, the following 
names:
