The abundant species of sub-group (a) are Nos. 3, 4, 6, 12, 13, 14, 20, 21, 22, 

 24, 25, 28, 29, 31 and 34. Nos. 7, 10, 11, 16, 17, 19, 23, 30, 33 and 35 are also 

 common, whJe Nos. 2, 5, 9 and 27 are not infiequently met with. The others 

 are laie in this district, Nos. 8, 18 and 32 being doubtfully included in this group. 

 Nos. 9, 10 and 11 form a sub-group by themselves, intermediate between Groups 

 I and II. They seem to prefer the low parts of the shoies of the river and the quiet 

 inlets where there is a marshy tendency, but little oi no growth of reeds or similar 

 maish vegetation. This type of habitat grades on the one hand mto sub-group 

 (b) of Group I and on the other hand into sub-group (a) of Group II, in which they 

 have been included. 



No. 32 is peculiar to the lagoons of Giant's Tomb Island. 



Of sub-group (b) Nos. 1, 3, 4, 9, 10, and 11 are abundant, 9 being, however, 

 local. Nos. 5, 6 and 11 are more characteristic of sub-group (a). Nos. 3 and 9 

 breed in the sphagnum bog some distance from the edge of the open watei . 



Helocordulia uhleri, Leucorrhinia glacialis and L. hvdsonica probably also 

 belong to Group II, but we have never found their nymphs.
