matter of this work, but also papers dealing with the Histology, 

 Embryology, and Physiology of the type, as well as a certain number 

 of works, which, although not dealing specifically with Salamandra, 

 have sufficiently important general bearings to justify their admis- 

 sion. This list does not pretend to be complete except in so far as 

 the anatomy of Salamandra is concerned, and there must inevitably 

 be many omissions. Nevertheless it is offered with the confidence 

 that it will prove an adequate guide for any future investigation, 

 either of Salamandra itself, or of any other closely related Urodele. 

 In this connexion I must acknowledge with gratitude the invaluable 

 assistance which has been freely given by the Librarian and staff of 

 both the Zoological and General Libraries of the British Museum 

 (Natural History), of the Science Library, South Kensington, the 

 Library of the Royal College of Surgeons of England, and of the 

 Royal and Zoological Societies. My importunate demands for books 

 have always been met with courtesy, and expert advice in tracking 

 down obscure references has been placed ungrudgingly at my disposal. 

 To my Tutor, Professor F. J. Cole, F.R.S., in whose laboratory 

 the work has been done, my sincerest thanks are due. He is respon- 

 sible not only for the original plan of the work, but also for stimu- 

 lating its progress in times of doubt and difficulty. Moreover, he has 

 closely associated himself with its publication by writing the His- 

 torical Introduction. I owe a debt of gratitude to Dr. N. B. Eales, 

 whose constructive criticisms have helped to rectify many blemishes, 

 for sharing with Professor Cole the arduous task of reading the 

 proofs of this work. Their aid has been invaluable. I also desire 

 to thank the numerous other Zoologists who have assisted in 

 various ways. Among them I would name especially Dr. Chas. H. 

 O'Donoghue, of Edinburgh University, who has offered valuable 

 suggestions on problems connected with the vascular system, and 

 Dr. F. H. Edgeworth, of Bristol, who has very kindly placed at my 

 disposal his knowledge of muscle terminology — particularly in 

 respect of the hyobranchial apparatus, and finally Professor H. 

 Graham Cannon, of Manchester University, who has given very wel- 

 come technical advice with regard to the illustrations. I have also to 

 acknowledge my indebtedness to the Council of the Royal Society 

 and the Research Board of Reading University for generous grants, 

 without which the publication of the work in its present form 

 would not have been possible. E. T. B. F.
