ion of Holothuria robsoniy Cuciimaria thomsoni and Labidodesmus 
tiirbinatus and thus was able to give the information wanted re- 
garding the calcareous deposits a. o. of those species. He could then 
also give the proof thatThéel’s Stichopus sordidus was the same 
as Hutton’s Holothuria mollis, and that Théel’s Thyonidium ru- 
gosum was the same as Hutton’s Thyone (Pentadactyla) longidentis, 
with which species also Hutton’s Thyone caudata was found to 
be identical. In the same paper three new species from New Zea¬ 
land are described, viz. Cucumaria Huttoni, Colochinis ocnoides and 
Colochirus calcarea. 
H. Ludwig (Holothurien d. Sammlung Plate. Zool.Jahrb. Suppl. 
IV. 1898) declares Dendy’s Colochirus calcareus a synonym of 
Coloch. brevidentis Hutton, and in another paper in the same year 
(Holoth. d. Hamburg. Magalhaens. Sammelreise) shows that the Chiri- 
dota australiana mentioned byThéel is in reality Trochodota pur- 
purea (Lesson), the locality being the Falkland Islands, not New 
Zealand. 
In the “Report on the Holothurioidea collected by Prof. Herd¬ 
man at Ceylon in 1902”^) Joseph Pearson identifies a Ceylon 
Holothurian with Hutton’s Labidodesmus turbinaius, Herd man 
having compared for him his description and figures with the type 
specimen in the British Museum and found no objection to this 
identification. Since, however, the calcareous deposits of the type 
specimen had been dissolved, there is, in faet, no guarantee what- 
ever, that the identification is correct, and, moreover, zoogeographical 
reasons are decidedly against such identification. As there is hardly 
any possibility for identifying with full certainty any New Zealand 
species with Hutton’s Labidodesmus turbinatus, we may perhaps 
rather leave that name to the ceylonese species described by Pear¬ 
son under that name, designating it Cucumaria turbinata (? Hutton) 
Pearson, the species then disappearing from the New Zealand fauna. 
The next contribution to the New Zealand Holothurian fauna 
is due to R. Per ri er, who describes in 1905 in his paper “Holo- 
thuries antarctiques du Mus. d’hist. nat. Paris’’^) the following new 
species: Cucumaria Filholi, Phyllophorus anatinus and Caudina pul- 
chella, as also a new variety, brevicauda, of Caudina coriacea. —
