In his monograph on “The Apodous Holothurians” 1907 H. L. 
Clark 'declares Caudina coriacea to be identical with Caudina 
chilensis (Joh. Muller). 
In another most important paper by Dendy & Hindle, “Additions 
to our knowledge of the New Zealand Holothurians” (Journ. Linn. 
Soc. Zool. XXX. 1907) all the new species described by Per ri er 
are declared to be identical with species described by Hutton. 
In this paper are further described the following new species: 
Stichopus simulans, Phyllophorus dearmatus, Pseudocucumis bicolum- 
natus, Chirodota gigas (Chatham Island), Chirodota geminifera and 
Rhahdomolgus novæ-zealandiæ. For the latter species a new genus, 
Kolostoneura, was established by S. Becher in 1909.^) 
Finally in 1909 Dendy described in his report on the Holo¬ 
thurians in the “Subantarctic Islands of New Zealand” a new 
species, Chirodota benhami and a new variety, carnleyensis of Cu- 
cumaria brevidentis, while Cucumaria leonina Sunper is recorded as 
new to the New Zealand fauna. In the same year Ben ham, in 
his report on the Echinoderma of the N. Z. G. Trawling Expedition 
describes the new species Molpadia dendyi and adds Molpadia 
marenzelleri Théel, hitherto known only from the Deep-sea off New 
Zealand (700 fms.) to the New Zealand fauna. 
In the present paper the following 10 new species are described: 
Holothuria neozelanica, Cucumaria amokuræ, C. Farquhari, C. Bollonsi, 
C. leoninoides (the species determined by Dendy as C. leonina), 
Psolidiella nigra, Psolus neozelanicus, Chiridota nigra, Ch. carnleyensis 
and Trochodota Dendyi^ while one, Pseudopsolus maquariensis (Dendy) 
is added, with some doubt, to the New Zealand fauna. Also a new 
variety, microurna, of Trochodota dunedinensis is described. Further 
Cucumaria calcarea and Caudina coriacea are reestablished as sepa¬ 
rate species, while Stichopus simulans is declared synonymous with 
St. mollis, Chiridota benhami and geminifera synonymous with Tro¬ 
chodota dunedinensis, and Synapta inæqualis with Protankyra uncinata. 
A new genus, Psolidiella, is established. 
The type-specimens of Hutton’s Holothuria Robsoni, Cucuma¬ 
ria thomsoni and Labidodesmus turbinatus being found in the British 
Museum, I applied to Dr. C. C. A. Mon ro for a bit of skin of 
i)Siegfried Becher. Die systematische Stellung des Rhabdomolgus 
novæ-zealandiæ, Arch. zool. expér. & genér. 5 Sér. I. 1909.
