also seems to have suspended its function as a food-absorbing 

 organ. This depends upon the development of secondary nutritive 

 organs, viz. the offshoots or filaments of the peduncle. These 

 filaments are prohably supported in their dissolving influence on 

 the shark's tissues by secretions from the cementary glands, the 

 latter being numerons and of great size in Anelasma. The 

 cementary glands do not here, as in oither pedunculate cirripeds, 

 gather into two groups, or send their secretions to the base of the 

 peduncle throuigh two main ducts. The single gland cells comimun-- 

 icate through short ducts wiith the lacuneis of the connective 

 tissue in Anelasma.
