 writer has to tender his best thanks to several gentlemen : — To 

 Mr. J. Stanley Gardiner and Dr. A. Willey for permission to 

 examine their collections, to Messrs. B. I. Pocock and F. Jeffrey 

 Bell of the British Museum for much kind advice and assistance, 

 and to Mr. Edwin Wilson for a great deal of trouble bestowed 

 upon a number of very difficult drawings. 



Note. — Errata in Parts II. and IV. of this paper : — On p. 458 

 of P. Z. S. 1898, for " Birgus latro (Linn.), 1766," read " Birgus 

 eatro (Linn.), 1767"; on p. 577 of P.Z.S. 1900, for "Gonio- 

 caphtrin^" read " CATOPTRESTiE," and for " GOXIOCAPHYRA TRUN- 

 catifrons de Man, 1887," read " Catoptrus A. M.-Edw., 1870."

 among the Gonoplacidae. De Man regards it as belonging to the 

 Portunidse, where it is placed in the present work. For synonymy,
