vi PREFACE. 



Tliomson, of Perth, Mr. E. Ray Lankester, tlie late Dr. 

 Adamson, of St. Andrews, the late Mrs. Macdonald, Mr. 

 Walker (the University Librarian), and many others have 

 also specially interested themselves in the marine animals of 

 St. Andrews. 



My thanks are due to the following gentlemen for their 

 valued aid in the several departments : viz., to Dr. Bower- 

 bank in the Sponges ; Mr. H. B. Brady, in the Foraminifera ; 

 Mr. Busk and the Eev. T. Hincks, in the Zoophytes and 

 Polyzoa ; the Rev. A. M. Norman, in the Echinoderms, and 

 also, with Mr. Spence Bate and Mr. G. S. Brady, in the 

 Cmstacea ; and Dr. Gwyii Jeffreys, in the Mollusks. I have 

 also to remember the kind attention, in regard to the Uni- 

 versity Library and Museum, of Principal Tulloch, Professors 

 Bell, Macdonald, and Heddle ; while Mr. R. Walker, the 

 Librarian, has supplied me with the names of a few ad- 

 ditional fishes. 



The Plates are the earlier efforts of my late sister ; and the 

 vignettes (with the exception of a sketch of the Harbour by 

 my nephew) are reduced outlines of various pictures and 

 coloured drawings by the same lady, who, with otlier relatives, 

 was equally persevering in collecting and in portraying. 



The lists for the most part appeared in the 'Annals and 

 Magazine of Natural History' for the present year (February 

 to December). 



I have to acknowledge, in conclusion, the skilful touch of 

 Mr. Ford in his rendering of the Plates. The Woodcuts 

 were engraved in Edinburgh, by Mr. J. M. Corner, who 

 spared no pains in their execution.
