OF ARTS AND SCIENCES : OCTOBER 14, 1862. 65 



742 of Thurber, &c. But some of Wright's specimens, and no. 74 

 and a part of IS'' of Wislizenus's, have the tube of the corolla as short 

 and funnel-shaped as in the following. 



/3. Thurberi (P. TJmrheri, Torr. in Pacif. R. R. Exped. 7, p. 15, 

 hot. appx.). Corolla minor, brevior, hand semipollicai'is, tubo magis 

 dilatato, fauce lineis 2 barbatis antice instructa. — Here belong Dr. 

 Antisell's specimens from the Burro Mountains, and Thurber's 1056 

 from Ojo de Gavilan, New Mexico, as described by Dr. Torrey, fi'om 

 Prof Thurber's notes. The distinctions are well taken ; but the speci- 

 mens mentioned above make me hesitate to admit the species.
