viscid secretion is required to surround and entangle the insects 

 trapped in the cheek-pouches (?) and spaces between the palatal 

 ridges and oral vestibule ; and large glands are also present in 

 the insectivorous Ccunolestes ohscicrus (9) *. In Sarcophilus 

 harrisi the total mass of salivary glands is small, but the sub- 

 maxillaries form the chief part. 



In the Diprotodonts the submaxillary glands are single or lobu- 

 lated, and the largest ones are present in the various species of

Dendrolagus. tSmall isolated glands are present between the 

 main masses in Macropus giganteus (text-tig. 1\,g), but the small 

 glands are united to the main masses in Dendrolagus icrsinus 

 (text-fig. 74, g). And in these genera I traced small sympathetic 



* In insectivorous Marsupials the glands are relatively smaller than those in the 

 insectivorous Edentata.
