PECULIAE GLANDS. 



In certain Genera and Species peculiar glands are found 

 subserving special functions ; e.g. sebaceous follicles of tbe 

 skin secreting a strong smelling, unctuous fluid ; anal sacs, 

 or glands ; and others on the back, legs, and feet. 



Quadrumana. In Cheiromys, and some other Lemuridae, the 

 anal glands are reduced to two shallow cutaneous pits at the sides 

 and upper part of the vent ; in higher Quadrumana this trace dis- 

 appears. 



Insectivora. In many Shrews two longitudinal series of glandular 

 tubes open upon the sides of the body opposite to the anterior feet, 

 the secretion of which has a more or less musky odour; and in 

 certain large Shrews {e.g. Macroscelides) the under part of the base 

 of the tail is tumid, through the development of the glandular 

 follicles. 



Cheiroptera. In certain tropical bats {e.g. Cheiromeles) a glandu- 

 lar exuding sac is situated near the axilla : and in some Yesperti- 

 tiones upon the sides of the upper jaw. 



In the Rodentia and Sector ialia anal sacs, and preputial glands 

 close to them, are of frequent occurrence, especially noticeable in 

 Castor idse (Eodentia) and Viverridae (Sectorialia). 



Prohoscidia. In Elephas a large gland is situated in the temporal 

 region, especially^^developed in the rutting season. 



Artiodactyla. Interdigital glands are generally found which 

 exude their lubricating secretion from an orifice at the upper and 

 fore part of the cleft between the principal hoofs. In Dicotyles is 

 found a gland situated rather posteriorly upon the mid-line of the
