Summary

Description
English: Fig. 68.—Diagram of three Branchial Segments of Ammocœtes (A) compared with three Branchial Segments after Transformation (B) to show how the Branchial Appendages of Ammocœtes form the Branchial Pouches of Petromyzon. (After Nestler.)


In both figures the branchial cartilages (br. cart.), the branchial view (V. br.), and the sense-organs (S), are marked out in order to show corresponding points. The muscles, blood-spaces, branchial arteries, etc., of each branchial segment are not distinguished, being represented a uniform black colour. Bro., the bronchus into which each gill-pouch opens.


(All references in this work to Ammocœtes or Petromyzon appear to refer to the European Brook Lamprey, now called Lampetra planeri.)
