It would appear that successful fertilisation may be effected by 
applying the pollen from the long stamens to the stigma of the 
long styles. 
The partial fruiting which took place in the heads of flowers in 
the Hookerian plants may have depended on the fact that there 
were only produced flowers with long stamens and short styles, and 
although when pollen was applied from one flower to another 
fertilisation was effected, still it was by no means fully successful, 
only two or three of the flowers in the head producing fruit. The 
flowers are sweet-scented with a delicate odour.

2. On the Crinoids of the “ Porcupine ” Deep-Sea Dredging- 
Expedition. By Professor Wyville Thomson. 
Seven species belonging to the Echinoderm order Crinoidea, 
were procured during the “ Porcupine ” dredging expeditions of 
1869 and 70. Four of these belong to the free section of the order, 
and are referred to the genus Antedon. 
1. A. escrichtii, J. Muller. 
This fine species is abundant off the coast of (Greenland, but so far 
as I am aware, it does not occur in the seas of Scandinavia. 
Several hauls of the dredge in the cold area in the channel between 
Scotland and Faeroe, yielded many examples, the largest of which, 
however, fell somewhat short of the dimensions of the largest 
specimens from (Greenland. Antedon escrichtii was associated in 
the Faeroe channel with Ctenodiscus crispatus , an Asteridean which 
had been met with previously only in the Greenland seas. A 
single example of a pentacrinoid in an early stage was found 
associated w*ith Antedon escrichtii. It resembled closely the larva 
of Antedon sarsii, but the specimen was not sufficiently perfect for 
a critical examination.
