than 1 cm. The tuhce have a winding course, measuring along the undulations 19 — 20 

 cm. from the pavilion to cornua uteri. The tuhce seem to be considerably wider in their 

 abdominal end near the ostruin abdominale and then navrowed towards the uterine end. 

 There may thus easily be distinguished an ampulla tuhce and an isthmus tuhce which is 

 a remarkable difference as well from the condition found in the coinmon ox as that 

 found in the sheep, in both of which the tuba3 are continued more directly in the uterus. 

 Ostium uterinum tuhce is, however, not extremely narrowed, as for instance in the horse, 

 but measures about 1 mm. in width. Cornua uteri are in this stage 13 — 14 cm. in 

 length. The cotyledonal processus are very distinctly arranged in i'ows and partly con- 

 fluent into folds. The number of rows is five, nameiy two on the mesial and three on 

 the lateral side. The cotyledonal processes of the median side are larger than those of 

 the lateral ones. The number of cotyledons in one of the cornua was as follows, in the 

 median rows resp. 17 and 15 in the lateral rows resp. 15, 9, 16. The number of 

 cotyledonary papillaa in each cornu may thus be estimated at 70, more or less, or about 

 140 in all. This is low compared with the number of the muskox but larger than in 

 the common cow (80 — 130 according to Franck^)) and still larger than the same in goats 

 and sheep (88 — 96^). If the arrangement of the cotyledonary papillas in five rows sbould 

 not be an individual variation, which seems less probable as it is alike in both cornua, 

 it is an important character. In the lower part of cornua. uteri of a common cow I have 

 also distinguished a similar arrangement of the cotyledonary papillffi in five rows. Corpus 

 uteri is very short, not even measuring 1 cm. in length. Cervix uteri is also short, not 

 much inore than 1 cm- in length and with its hirger part {Portio vaginalis 1 cm.) pro-- 

 truding into vagina; Canalis cervicalis is wide, more than V2 cm. and its wall is provided 

 with longitudiiial folds. The thickness of the wall is about 5 mm. In spite of the 

 width of the canalis cervicalis the opening into the vagina is sufficiently protected by 

 two large valves which completely surround cervix uteri so that it cannot even be seen 

 when the vagina is opened before at least one of ^these valves has been cut through. 

 The dorsal one of these valves is the outer, but the ventral and interiör one which is 

 the larger nearly completely envelops cervix uteri so that it sticks in a pocket. The 

 walls of these valves are thick and strongly muscular and their surface shows longitudinal 

 folds. The length of the vagina from orificium uteri to the edges of lahia pudemli is 

 about 17 cm. It is widened interiorly so that it is extremely spacious in its interiör 

 portion, about 7 — 8 cm. The wall of this portion is thin compared with that of a cow. 

 Unlike the condition in Ovihos there is no liymen developed. The urethra opens ventrally 

 in the vagina with a large longitudinal fissure 5V2 cm. from the margin of lahia pudendi. 

 There is thus no diverticulum suhuretlirale. At the ventral angle formed by lahia pudendi 

 is the very small clitoris. 



The shortness and width of canalis cervicalis uteri of the gnu is much different 

 from the nan-ow winding passage^) found in the same organ of goats and sheep. But the
