CRAWLEY, Howarp. Initial stages of 
Sarcocystis infection. 
Science (n. s.), 37, No. 
952, Mar. 28, 1913, 
p. 498. 
———— Two new Sarcosporidia. 
Proc. Acad. Nat, Sci., 
Phila., Apr. 21, 1914, 
pp. 214-218, 1 fig. 
Describes Sarcocystis leporum 
from a rabbit, and S. setophage 
from a redstart (Setophaga ruti- 
cilla). 
———— The evolution of Sarcocystis 
muris in the intestinal cells of the 
mouse. (Preliminary note.) 
Proc. Acad. Nat. Sci., 
Phila., June 24, 1914, 
pp. 432-436, pl. 15, | 
figs. 1-12. 
Describes the development of 
this parasite into two markedly 
dissimilar groups which are in- 
terpreted to be males and fe- 
males. The first positive evi- 
dence of sexuality in the Neo- 
sporidia is supplied by the facts 
recorded in this paper. 
Hartt, Maurice C. A new nematode, 
Rictularia splendida, from the coy- 
ote, with notes on other coyote para- 
sites. 
Proc. U. 8. Nat. Mus., 
46, No. 2012, Aug. 
23, 1913, pp. 73-84, 
figs. 1-6. 
Describes a new species of 
nematode from the small intes- 
tine of Canis nebracensis from 
Amo, Colorado. A new subfam- 
ily of the family Metastrongy- 
lide, is proposed, Rictulariine, 
having Rictularia Froélich, 1802, 
as the type genus. A key is 
given for distinguishing the 
three species of Rictwlaria para- 
sitic in carnivores. The species 
of parasites known to affect 
coyotes are listed, and Tenia 
pisiformis is recorded for the 
first time as a parasite of coy- 
otes. 
FIARRING, Harry K. A list of the Rota- 
toria of Washington and vicinity, 
with descriptions of a new genus and 
ten new species. 
Proc. U. S. Nat. Mus.,

405, pls. 34-38. 
Harrinc, Harry K.—Continued. 
The list of Rotatoria of Wash- 
ington, D. C., and adjacent parts 
of Maryland and Virginia num- 
bers 246 species. The new genus 
described is Rousseletia (order 
Ploima) with the new species 
Rk. corniculata. The other new 
species are as follows: Encen- 
trum aper, EB. myriophylli, BP. 
riccle, Lecane stichewa, Mono- 
styla acus, M. crenata, M, syl- 
vatica, Trichotria brevidactyla, 
and Asplanchnopus hyalinus.

pls. 12-18. 
Description of  Oysticercus 
bovis, and discussion of the 
parasite with particular refer- 
ence to its importance in meat 
inspection. It occurs in not less 
than 1 per cent of all cattle 
slaughtered in the United States, 
its prevalence being attributable 
to poor sanitary conditions in 
rural districts, and the common 
habit of eating raw or imper- 
fectly cooked beef. 
The name of the sheep measle 
tapeworm.

Reports results of experiments 
proving the parasite of sheep 
measles to be the intermediate 
stage of a dog tapeworm, and 
not the intermediate stage of 
Tenia solium of man as com- 
monly supposed. This parasite 
has recently been found to be 
very common among sheep in
