ever, evident that it is not a Thyone, but belongs to the family Aspidochirota, 
and must form the type of a new genus, distinguished by having only five 
tentacles and scattered foot-papille. I therefore propose the name Penta- 
dactyla for it. 
Holothuria mollis, Hutton. 
This species in many respects approaches Stichopus. I have had no 
specimens for dissection, and cannot therefore say whether the reproductive 
organs are in one or two bunches. A knowledge of this will settle to which 
genus it should be referred. 
Holothuria robsoni, sp. nov. 
Elongated, rather slender. Skin, smooth. Feet, scattered sporadically 
over the ventral surface, apparently none on the back. Pentacles, 20. 
Anus, round. Back, pale purplish brown; ventral surface, dirty white, 
with scattered brown spots. Length, 4i inches. 
Cape Campbell. Presented to the Museum by Mr. C. H. Robson, to 
whom I have much pleasure in dedicating it. 
Art. XXXII.—The Sea Anemones of New Zealand. By Prof. Hvrrox. 
(Read before the Otago Institute, 11th June, 1877.] 
I sgovrp not have chosen such a pretentious title for this paper, but that I 
wished to include in it descriptions of the three New Zealand sea anemones 
that have not been found near Dunedin. The sea anemones are animals 
that can only be described from living specimens; they must be collected, 
brought home alive, and placed in water before their structure and colour 
can be seen, and when they are dead there is no known means of preserv- 
ing them so as to be of any use. To enable observers, therefore, in any 
part of the colony away from libraries, to describe these animals, I have 
included in this paper not only descriptions of all the New Zealand species 
not described in our Transactions, but also an analysis of all the known 
genera.
