. Bulletin - United States National Museum. Science. 2G8 BULLETIN 34, UNITED STATES NATIONx\L MUSEUM. The head is short aud wide, and its length varies so as to enter from four to four aud a half times in the total length. The extended hind leg brings the heel to the posterior lower or middle of the orbit. The muzzle viewed from above is rounded, aud in profile is truncate, and not projecting beyond the premaxillary border. It is shorter than the length of the orbit, and the nostrils are terminal. The tongue is flat and thin, and is a long oval in outline. The membranum tymiiani is quite distinct, and is subround. Its diameter is a little less than half the length of the eye slit. The parotoid gland varies in form from nearly round to a moderately elougate-oval; in either case it has an anterior prolongation to the border of the orbit. The glands of the in- tegument of the upper surfaces vary from moderate to large size. They are smaller on the sides and on the limbs, excepting a large oval one on the superior face of the tibia. The inferior surfaces are coarsely areolated, with a few more distinct tubercles posteriorly. There is an infolded ridge on the inner edge of the tarsus. The pos- terior foot varies in relative width in different individuals and locali- ties. In northern specimens the sole is wider, and the palmatiou extends to the ends of the toes. It is emarginated, so that the edge is. ¥ig. Qd.—Bufo columMensis colmnhionsis. No. 1151G. Kowaldn Valley, "W. T.; {. Measnrcinents of No. 328.
