Mexican Cliff Swallow, Petrochelidon melanogaster (Swainson), in abund- 

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

 into Arizona, along the San Bernardino and Santa Crviz 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-

A new Cypripedium. 



Cypripediiim veganvm, n. sp. — Allied to C. pvhescens and C. paniflor- 

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

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

 in the large flowers, but the lip is very bright yellow as \n parvifldrum. 

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

 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 dvill 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.

A new name for Mus obscurus Miller. 



The name Mtis obsvurus 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 

 ohsrurii.t Waterhouse (Proc. Zool. Soc. London, Y, p. 19, 1S37). It may 

 therefore be replaced by Mufi pulluH. — Gn'rit S. Miller, J?-.
