Drosophyllum, but differs in the following points. I 

 could detect no sessile glands ; nor would these have 

 been of any use, as the upper surface of the leaves is 

 thickly clothed with pointed, unicellular hairs directed 

 upwards. The pedicels of the tentacles do not include 

 spiral vessels ; nor are there any spiral cells within the 

 glands. The leaves often arise in tufts and are pin- 

 natifid, the divisions projecting at right angles to the 

 main linear blade. These lateral divisions are often 

 very short and bear only a single terminal tentacle, 

 with one or two short ones on the sides. No distinct 

 line of demarcation can be drawn between the pedi- 

 cels of the long terminal tentacles and the much 

 attenuated summits of the leaves. We may, indeed, 

 arbitrarily fix on the point to which the spiral vessels 

 proceeding from the blade extend ; but there is no 

 other distinction. 



. It was evident from the many particles of dirt stick- 

 ing to the glands that they secrete much viscid matter. 

 A large number of insects of many kinds also adhered 

 to the leaves. I could nowhere discover any signs 

 of the tentacles having been inflected over the cap- 

 tured insects ; and this probably would have been seen 

 even in the dried specimens, had they possessed the 

 power of movement. Hence, in this negative cha- 

 racter, Koridula resembles its northern representative, 

 Drosophyllum.

Bijhlis gigantea (Western Australia). — A dried 

 specimen, about 18 inches in height, with a strong 

 stem, was sent me from Kew. The leaves are 

 some inches in length, linear, slightly flattened, with 

 a small projecting rib on the lower surface. They 

 are covered on all sides by glands of two kinds
