1 Dr Pfeffer has been good enough to furnish me with a number of additional 

 particulars regarding this form, which leave no doubt that it should be referred 

 to the genus Taonius. 



2 If I am correct in referring this form to the genus Taonius, the specific 

 designation is singularly unfortunate ; minimus would have been more appro- 

 priate ; but in the present state of our knowledge it is not worth while to 

 burden the animal with another name, more especially as it is not improbably 

 the young of one of the other forms.
