 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. 



Hall, Maurice C. A new nematode, 

 Rictularia splendida, from the coy- 

 ote, with notes on other coyote para- 

 sites.

 figs. 1-6. 

 Describes a new species of 

 nematode from the small intes- 

 tine of Canls nehracensis from 

 Amo. Colorado. A new subfam- 

 ily of the family Metastrongy- 

 lidse, is proposed, Rictulariinte, 

 having Rictularia Frollch, 1802, 

 as the type genus. A liey is 

 given for distinguishing the 

 three species of Rictularia para- 

 sitic in carnivores. The species 

 of parasites Ijnown to affect 

 coyotes are listed, and Twiiia 

 pisiformis is recorded for the 

 first time as a parasite of coy- 

 otes.

 bers 246 species. The new genus 

 described is Rousselctia (order

 R. corniculata. The other new 

 species are as follows : Encen-

 Description of Cysticercus 

 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 coolced beef.

 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 

 Twnid solium of man as com-

 has recently been found to be 

 very common among sheep in
