178 General Notes. 



Mexican Cliff Swallow, PetrocJielidon melanogaster (Swainson), in abund 

 ance in the states of Chihuahua and Sonora, Mexico. It also crossed 

 into Arizona, along the San Bernardino and Santa Cruz rivers, breeding 

 on both sides of the international boundary line. Five or six specimens 

 including adults of both sexes and young recently from the nest, were 

 collected in Arizona, and are now in the United States National Muse 

 um. Edgar A. Mearns. 



A new Cypripedium. 



Cypripedium veganum, n. sp. Allied to C. pubescens and C. parviflor- 

 um. Differs from both, but especially from parviflorum, by the oblong 

 stigma, rounded and almost truncate at the end. Agrees with pubescens 

 in the large flowers, but the lip is very bright yellow as in parviftorum. 

 Leaves and stems glabrous, with only a few scattered gland-hairs. t 

 Flowers very slightly fragrant. 



Upper sepals as long as the lip; lower much shorter; petals narrow, 

 longer than the lip, usually twisted. Lip much inflated, laterally com 

 pressed, pubescent at base within, speckled with dull red within, faintly 

 speckled on outside above towards the apex; sterile stamen triangular, 

 spotted like the lip. Leaves lanceolate. Stems a foot to a foot-and-a- 

 half high. 



Measurements in millimeters: Upper sepals, length 35-45; lower, 

 length 32-40; breadth, (two united) 15-19; petals, length 45-57; greatest 

 breadth, 7: lip, length, 33-41; breadth, 14-19; sterile stamen, length, 14,, 

 breadth, 6. 



Leaves with about 6 prominent and 6 weaker veins; average of the 

 larger leaves, length, 135, breadth, 40. 



Hob. Sapello Canyon, Las Vegas Range, N. M., about 8000 ft. (Cana 

 dian Zone); in full flower in June. Many specimens examined. The 

 type will be placed in U. S. National Museum. T. I). A. Cockerdl and 

 P. and M. Barfar. 



A new name for Mus obscurus Miller. 



The name Mus obscurus which I recently applied to a small rat from 

 Tioman Island, off the east coast of the Malay Peninsula (Proc. Wash 

 ington Acad. Sci., II, p. 213, August 20, 1900) is preoccupied by Mus 

 obscurus Waterhouse (Proc. Zool. Soc. London, Y, p. 19, 1837). It may 

 therefore be replaced by Mus pullus. Gerrit 8. Miller, Jr.
