The rhinarium of the two forms I have examined—namely, frontalis, which is almost certainly a domesticated breed of B. gaurus, and banteng—does not differ in any important riff. A. End of penis of African buffalo (Syncerus coffer cequinoctialis?) from the left side. B. The same of zebu (Bos indicus). C. The same from below. D. The same of banteng (Bibos banteng) from left side. E. The same of gayal (Bibos frontalis) from below. F. The same of American bison (Bison bison) from the side. G. The same from below. respects from that of Bos, although the dorsal surface seems to be less overgrown witli hair than even in B. indicus. The hair encroaches only to a slight extent between the posterior angles of the nostrils, so that the posterior border of the tipper side is lightly concave. This feature may, however, prove to be variable. In the feet the interlingual integument is naked as in Bos, not hairy as in Bison. The penis (fig. 4, D, E) in both the above-mentioned species differs from that of Bos in that the urethral canal is.
