MONOGRAPH OF THE GENUS PERIPATUS. 433 



very considerable trouble and inconvenience to satisfy what 

 would have seemed to most people an absurd whim of a perfect 

 stranger. The living animals brought by Mr. Evans have 

 enabled me to give a much more complete account of the New 

 Zealand species than if I had had to rely only on the somewhat 

 shrunk and contracted specimens in Balfour's material ; and 

 the embryos found in them are now being used by Miss Sheldon 

 (No. 45), of Newnham College, who is engaged in preparing a 

 memoir of their development. 



4. Several specimens of the neotropical group of species 

 from the Museum of Copenhagen, most kindly sent to me by 

 Professor Steenstrup, in response to the appeal for specimens 

 at the end of Balfour's posthumous memoir. 



5. Dr. J. Kennel, of Wurzburg, was kind enough to send 

 me, in exchange for two living specimens of Capensis, 

 two specimens of the smaller species, which he found in 

 Trinidad. 



6. Four specimens from near William stown, South Africa, 

 belonging to the Indian Museum. 



7. All the specimens in the British Museum. These have 

 not, unfortunately, been of so much use to me as I had hoped, 

 on account of their small number and contracted condition, 

 and of the difficulty of getting a sufficiently strong light in 

 the rooms set apart for the examination of spirit specimens 

 in the British Museum, for the minute examination which is 

 required. I am greatly indebted to Professor Jeffrey Bell, of 

 the British Museum, for his courtesy in giving me every 

 facility in his power to examine the specimens. 



8. Two specimens from Queensland, Australia, belonging to 

 Professor Jeffrey Bell. He has been most kind in putting 

 them entirely at my disposal for the purposes of this mono- 

 graph. 



9. About twenty specimens from Demerara, brought alive 

 to England by Mr. W. L. Sclater. Mr. Sclater has himself 

 given a short description of these specimens, and has kindly 

 placed the greater number of them at my disposal for the 

 purposes of this monograph. These specimens were all killed
