Arachnoides placenta Linneus. 
Farquhar, loc. cit., 1898, p. 321. ; 
This ‘‘ cake-urchin,” or, rather, ‘ biscuit-urchin,” is common on 
sandy beaches. Only one specimen was received, without indica- 
tions of locality; but, as it is widely distributed, this omission is 
immaterial. 
Echinocardium australe Gray. 
Farquhar, loc. cit., 1898, p. 322. 
Station 30, 
Only three individuals were preserved ; they are quite immature. 
Probably, living as they do imbedded in the sand, the trawl missed 
many other specimens, for they must be fairly abundant. 
Localities—Off Oamaru. [It is very common round the South 
Island. It would be interesting to ascertain how far north it occurs. | 
HOLOTHUROIDEA. 
Phyllophorus longidentis Hutton. 
Thyone longidentis Hutton, Cat. Ech. N.Z., 1872, p. 16. 
Phyllophorus longidentis, Dendy and Hindle, Journ. Linn. Soc. (Zool.), 
xxx, 1907, p. 101, gives literature and synonyms. 
Station 95. 
One complete small individual and many, more or less digested, 
specimens were obtained from the stomach of the fish Pagrosomus. 
This suggests the desirability of examining the contents of various 
species of ground-feeding fishes for these and other mud-loving animals. 
Locality Off Whale Island, Bay of Plenty, 25-34 fathoms, sand 
and mud. 
Caudina chilensis J. Muller. 
Caudina coriacea Hutton, 1872; Dendy and Hindle, loc. cit., 1907. 
p. 108. 
Caudina chilensis, Clark, Smithsonian Contributions, xxx, 1907, p. 175 
(full synonymy). 
Station 7. 
A single specimen. 
Locality—South of Chasland’s, 43 fathoms, fine sand. 
Dr. Lyman Clark, in “ Apodous Holothurians,” 1907, p. 175, 
states that the specific name “ chilensis”” has priority over “ coriacea.” 
The species also occurs off Chili, Australia, Hast Indies, China, and 
Japan. 
Molpadia marenzelleri Théel. 
Ankyroderma marenzelleri Théel, ‘“ Challenger” Reports, xiv, 1886, 
p. 41, pl. ii, fig. 1.
