There is a cluster of unicellular salivary glands on each side of the oesophagus and the modified nonprotrusible proboscis lies in the mid-ventral region of the head below the oesophagus with its anterior portion protruding into the buccal cavity. The month, bnccal cavity and proboscis. A shallow oral groove, 30-40 /mi wide, originates at the anterior margin of the head and runs posteriorly on the ventral surface to the transverse slit-shaped mouth (Fig. IB). The mouth is 40-45 /un by 8-10 /un at rest but is capable of considerable distension during feeding. It opens vertically into a small ovoid buccal cavity which in turn leads.
