A number of other forms, some of which Mr. Rogers considers 

 of much interest, were collected, but these he will not undertake to 

 name at present. Some of them will be submitted to Dr. Focke, 

 and I hope to supplement this paper by a further note when his 

 remarks are received ; of others, a more complete series is required 

 for positive determination ; and others again will probably have to 

 be studied in their native habitat before they can be definitely 

 assigned to their proper place.
