IV. SPECIES AND VARIETIES RECORDED. 



By the time this Report was ready for impression the cost of paper and printing 

 had reached the point which is recorded for all time in the aspect of the Scientific 

 Journals of to-day. The Director, whilst giving us practically a free hand, appealed 

 to us to meet this situation. Apart from compression of the Introductory 

 portion of our report, we have endeavoured to meet it mainly by the suppression of 

 six thousand s}Tionyms. Excepting where necessitated by our " Notes,"' and in cases 

 where the discussion of life-histories renders an ample synonymy essential, we have 

 reduced our references to two — the original description and one reference to a work 

 in which either a sirfficient synonymy will be found, or works containing it are referred 

 to. Synonymies may be said to be virtually complete in Brady, 1884 F.C.,* 

 down to 1880 ; in Millett, 1898, etc., F.M. (who generally omits Brady and every- 

 thing before him, exceptmg the original author) do^\^l to 1903 ; and in Cushman 

 1910, etc., F.N. P.. doMTi to 1915. We have therefore made use principally of 

 these authors, especially Dr. J. Augustine Cushman. whose synonymies are a
