SUMMARY. This volume contains 561 figures, illustrating over 

 300 species of shells, and 571 figures illustrating the anatomy of 

 Helices; a total of 1132 figures. Of these, 330 figures were drawn 

 by the author; 203 other original figures were drawn by Messrs. 

 Wm. and Edw. Shepperd, and about a dozen are from unpublished 

 drawings supplied by friends. The figures of Flammullna cressida, 

 thaisa and costulata Hutton, were drawn by Mr. H. Suter from the 

 type specimens, these species being here for the first time illustrated. 

 The figures of Plectopylis ponsonbyi (pi. 40, fig. 9-12), and Papuina 

 ianthe (pi. 46, fig. 17-19) are from examples kindly loaned by Mr. 

 John Ponsonby from his collection. The other original figures are 

 from specimens in the collection of the Academy, where also most 

 of the author's dissections over 500 in number are preserved.
