I mentioned Ccirlier in tliis paper that many friends have 

 lent me material whicli has assisted me in the work on this 

 group. I have been specially assisted by Dr. Sharp, who has 

 not only lent me specimens but has also given me many hints 

 and has brought to my notice more than one paper relating 

 to the subject. I must also specially express my thanks to 

 Mr. Edwards, who, among other things, courteously allowed 

 me to see the specimens used in the preparation of his own 

 ])aper. His paper undoubtedly advanced our knowledge of 

 an exceedingly difficult group, especially as he discovered 

 the only absolutely reliable specific character. If I have 

 carried matters any further it is through him that I found the 

 necessary stimulus for the work.
