KO. 2012. A NEW NEMATODE FROM THE COYOTE— HALL. 83 



Colorado. The Colorado specimens were reported by Hall (1912a) as 

 Taenia sp., owing to the remarkable structure of the hooks on the 

 first specimen examined. Further study has shown that these hooks 

 were anomalies. Other material from the coyote in Montana can 

 not be placed more definitely at this time than as Txnia sp. It is 

 practically certain that coyotes are infested by Txnia Tiydatigena, 

 Multiceps serialis, and the adult stage of Cysticercus ovis, but there 

 are no records of these parasites from the coyote. 



Nematoda. — Ancylostoma caninum was reported from the intestine 

 of Canis latrans at Washington, District of Columbia, by Stiles and 

 Hassall (1894) under the name of Uncinaria trigonocepJiala. 



Belascaris sp. was reported from the intestine of Canis nebracensis 

 at Amo, Colorado, by Hall (1912a). 



Rictularia splendida, described as a new species in this paper, was 

 reported b}?^ Hall (1912a) under the name of Rictularia sp. 



Arthropoda. — Dermacentor venustus has been reported from the 

 skin of Canis lestes in Montana by Henshaw and Birdseye (1911). 



Sarcopies scahiei lupi has been collected from Canis latrans in 

 South Dakota, there being specimens in the collection of the United 

 States Bureau of Animal Industry, and this or a related variety has 

 been spread by artificial means among the coyotes of Montana under 

 the supervision of the State veterinarian. Dr. M. E. Knowles. Some- 

 thing similar is now being attempted in Wyoming. I have found a 

 division of opinion among Montana sheepmen as regards the efficacy 

 of sarcoptic mange as a means of eradicating coyotes, some claiming 

 that it was doing good and others clauning that it was doing no good, 

 or even doing some damage in cases where it was transmitted to sheep 

 dogs.
