74 M. O. Strobelt on the Anatomy and 



named naturalist especially, by the exact descriptions ana 

 correct and elegant figures in his classical work, has gained 

 great credit in connexion with these animals, which have 

 hitherto been under the ban of a deeply-rooted aversion, and 

 therefore have long been neglected. It is to him that we are 

 by no means least indebted for the present extent of our 

 knowledge of the Lice, of which far more than a thousand 



species are known. 



But however much our knowledge of the external form of 

 these animals has been advanced by the labours of the above- 

 mentioned and many other naturalists, little attention has 

 hitherto been paid to their internal anatomy. Upon the ana- 

 tomical structure of the Pediculina information has been given 

 by Swammerdam (16) among the older writers, and by a few 

 more recent ones, such as Simon (17), Landois (23-25), and
