 Jumping- Rat. [printed slip pasted on]"; reverse, eleven meas-

Specimens prepared as was customary by Dr. Cooper ; fore 

 legs extended forward and tied beneath throat; hind feet ex- 

 tended posteriorly and tied or crossed beneath tail; tail not 

 skinned, extended posteriorly, somewhat loose; abdominal in- 

 cision not sewed up. Specimens in fair condition. 



In general characters these examples agree closely with 

 specimens of Dipodomys merriami merriami from the Colo- 

 rado Valley, 



Zapus trinotatus trinotatus Rhoads 



"Jacidus hudsonius" Cooper, Pac. R. R. Expl. and Surv., 12, 

 book 2, 1860, p. 83 (Single specimen collected in Washington 

 Territory). 



Specimen examined.— One : No. 587/1710, U. S. Nat. 

 Mus. ; original label missing ; the catalog entry shows that the 

 skin was taken out of alcohol ; a label attached reads as follows 

 "N. Pacific R. R. Survey Gov. 1. 1. Stevens 587/1710 Meriones 

 hudsonius S [sex mark pencilled in] Shoalwater Bay, W. T. 

 [locality crossed out] W. T. [written in later, apparently in 

 same handwriting as name and Museum number] Dr. J. G. 

 Cooper." 



Specimen made over, after having been preserved as an alco- 

 holic. Skull in fragments. 



Its dark coloration shows the specimen to be referable to 

 Zapus trinotatus trinotatus rather than to Zapus princeps ore- 

 gonus, which is the only other jumping mouse known to occur 

 in the State.
