species new to Egypt, as well as to correct certain errors in the 

 literature concerning the previously known forms. 



In conclusion some reference should be made to what is meant 

 by the term « Egyptian" in this work, as in the past species have 

 been vaguely recorded as coming from Egypt without any clear idea 

 of the geographical boundaries of the country. It is very difficult 

 to adopt the present political boundaries for they are liable to be 

 changed and, moreover, they include at least four distinct faunas. 

 We have, therefore, adopted Storey's (1) suggestion ofl restricting 

 the term Egyptian to species coming from a more circumscribed 

 area including the Nile Valley from Assouan to the Mediterranean, 

 bounded on the East by the Suez Canal and a line running South 

 from about. Suez, and on the West by a line running South from 

 Mersa Matruh, so as to include the oases of Dakhla and Siwa. 

 Practically all the species described in this volume occur in the Nile 

 Valley itself, and in those few instances where they occur outside 

 this area, special attention will be drawn to them, in order to 

 prevent their being loosely classified as "Egyptian."
