A comparison of the structure of the scolex of Bothriocephalus scorpii (Müller 1776) and Clestobothrium crassiceps (Rud. 1819) and the mode of attachment of the scolex to the intestine of the host
1. Two Pseudophyllidea, Bothriocephalus scorpii (Müller) and Clestobothrium crassiceps (Rud.), have been obtained from Scophthalmus maximus (L.) and Merluccius merluccius (L.) respectively, from fishing grounds to the west of the British Isles. 2. The musculature of the scolex in both has been compa...

The effect on the mucosa is slight, due to the absence of very powerful muscles and of other specialized adhesive structures. 4.
