The Author holds that the so-called Semper's organ represents a buccal 



salivary gland and homologizes it with the ant. salivar\- glands of the 



Cephalopoda, the pharyngeal glands of the Amphineura, the buccal glands of 



the Prosobranchs, and the ' gland, ptyalinae ' of the Opisthobranchiata. The 



Semperian glands are ectodermal in origin, being derived from the stomadaeal 



epithelium.
