I am not prepared to say how good a character the squamation 

 of the feet may prove to be, but B. osgoodi exhibits scaly plates on 

 the hind feet similar to, but smaller than, those of B. squamipes. 

 They are not apparent on the fore feet nor on any of the feet of 

 B. thomasi which has the feet much more thickly haired than either 

 B. osgoodi or B. squamipes. 



In general size, color, and length of tail B. meridensis and B. 

 squamipes appear to be very similar, and it would be interesting to 

 know whether the former exhibits the marked squamation. 



''These shrews were first taken at the Hacienda Garzon on the 

 southern slope of Mount Pichincha, about on the level with the Casa. 

 They were trapped in runways along the banks of a deeply cut arti- 

 ficial ditch, the kind used in that country in lieu of a fence against 

 cattle. The location was wooded clearing and brush land, at that 

 point deeply shaded upland. The runways in location and character 

 were precisely like those made and used by Blarinas in the United 

 States." (S. N. Rhoads.) 



18. Didelphis marsupialis Linn. 



Didelphis marsupialis Linnaeus, Syst. Nat., ed. X., 1758, p. 54. 



One specimen obtained at Quito collected on the east side of 

 Cayambe. Also a ramus of a lower jaw found at Bucay, June 20. 



Mr. Osgood has compared the Cayambe specimen with true 



marsupialis of Guiana and Venezuela and finds but little difference 



except that it is somewhat larger. It may possibly be referable to 



D. m. colomhica Allen, type locality Santa Marta. 



19. Caenolestes fuliginosus (Tomes). 



Hyracodon fuliginosus Tomes, Proc. Zool. 8oc. London, 1863, p. 51. 

 (Ecuador.) 



Two female specimens of this little known marsupial were obtained 

 by Mr. Rhoads at Hacienda Garzon, near the paramo of Mt. Pichincha, 

 May 12, 1911, about three months after Mr. Osgood had rediscovered 

 the very closely allied C. obscurus on the Paramo de Tama on the 

 borderland of Colombia and Venezuela. 



So far as I am aware, no specimen of this interesting animal has 



been obtained in Ecuador since the type was taken by Fraser about
