In Nannotragus (nigricaudatus) it does not in the least resemble that of Cephalophus ; for it forms a slender, elongated, tapering cone, beyond which the urethra, which is free from it for the terminal g of an inch, continues straight on for g of an inch (fig. 21).

(scriptus) differs but little from this, except that the free portion of the urethra is wanting, and the end of it sliglitly turned upwards ; and in Damalis (pygarga) (fig. 22) the arrangement resembles that of Tra- Fig. 22.

According to Dr. Murie's accounts of the Prongbuck1 (Antilocapra americana) and the Saiga2 (Saiga tartaricd) the glans in these two animals differs from that in any of those above described, whilst from Pallas's account of the Musk (Moschus moschiferus)3 its penis is apparently ovine, as is that of the Giraffe (CameloparcJulis giraffa) (fig. 23).

Their absence I have recorded in C. elaphus, C. dama, C. cashmeerianus, C. aristotelis, C. moluccensis, C. porcinus, C. kuhlii, and C. campestris. Prof. Flower found them in C. pudu. I have seen them also in all species of Ovis, Capra, and Gazella examined, as well as in Cephalophus (maxwelli and pyg- » P. Z. S. 1870, p. 352. 2 P- Z- 8. 1870, p. 485.
