APPENDIX. 

 EEFERENCES TO TESTACELLA MAUGEI FEB. 



The literature on Testacella maugei is so extensive that 

 it has been deemed more convenient to give the following list 

 of some of the principal references to this species in the form 

 of an appendix. Those references in brackets relate to fossil 

 shells which have been assigned to T. maugei, although it 

 is possible that some of them, such as T. asinina, may have 

 belonged to species which, while nearly allied to this form, were 

 really distinct from it. Most modern writers place the form 

 found in New Zealand in this species, notwithstanding that 

 Hutton stated that its radula differed slightly from the type 

 usually found in T. maugei; I have therefore included the 

 references to it in the following list, although I have not had 

 an opportunity of examining a New Zealand example myself.
