zoological, and must be determined by laws of grammatical usa?e. The 

 terminations dm and nm must be accepted, but the preceding coincidence 

 of vowels is merely circumstantial, and must be dealt with accord- 

 ingly." 



In the matter of Question 7, the unanimous opinion of the 

 ten entomologists who expressed their views appears to be that — 



" 1. The type of a genus must be a species originally included in it 

 by the founder. 



" 2. The type must conform to the original description of the 

 genus (a species excluded by the description cannot be the type." 



There are other and mor^ complex matters connected with 

 this question, and about these there is far less unanimity. Some 

 other propositions have also been introduced, and it would there- 

 fore seem that the question must still continue an open one, 

 except as regards the two propositions quoted above. 



NOTES AND OBSERVATIONS. 



Emydia cribrum in the New Forest. — The late Mr. Bond's own 

 words, written in his interleaved copy of Stamton's ' Manual,' are as 

 follows : — " Near Ringwood, in the New Forest, about two miles upon 

 the Poole road, at a place called St. Lawrence, opposite the inn there." 

 If this very definitely described spot is misleading, I must apologise to 

 rny friend Mr. Eustace Baukes ; but, in the absence of personal know- 

 ledge of this old locality, I would suggest that two miles along the 

 Poole road from a spot near Ringwood need not necessarily be in the 

 Forest itself. The context of the situation of the public house would 

 supply the position near enough. There is no doubt that E. cribrum 

 is even now spread over mdes of country in apparently isolated com- 

 munities, and there need be no mystery over a fact so well known. —

Note on Cataclysta lemnata. — Some insects seem to have a re- 

 markable power of discovering any little place that will suit them to 

 live in, even though far away from their previous haunts. There is a 

 cemented tank, about six feet by five feet in size, here in the garden, 

 that is covered with duckweed, and there are some C. lemnata about it, 

 both male and female. If the surrounding country was full of ditches 

 and ponds and wet places it might be easily accounted for, but there is 

 no stream nearer than a mile, and that is dry half of every year, and 

 is far too swift when it does run for duckweed to grow on it. There 

 are two horse-ponds that catch rain-water within three or four hundred 

 yards, but curiously there is no duckweed growing on either of these. 

 So these moths must have come a long way to find this little tank. —
