Cucumaria Koellikert, Semp., hitherto known only from Sicily 
and Naples, has likewise under another name figured for some time 
past as a member of the Holothurian fauna of the Atlantic. I re- 
gard Cucumaria Lefevrii, Th. Barrois (1882), from Concarneau, as 
the same species, though certainly the figures of the calcareous 
bodies do not justify this supposition. I have already explained in 
my memoir on the Holothurians of the ‘ Hirondelle,’ at present in 
the press, that it is not advisable to follow Hérouard (‘ Recherches 
sur les Holothuries des cétes de France,’ Arch. Zool. Exp. [2] 
vol. vii. 1890) in regarding Cucuwmaria Lefevrii, with ten tentacles, 
as synonymous with Thompson’s old species C. Drumondii, which 
is now assigned to the genus Phyllophorus. Since I have in the 
meantime learned to know the species, I can now also protest 
‘ against Hérouard’s attempt to regard Thyone gemmata, Pourt., of 
the American coasts, as of the same value. In the determination 
of C. Koellikeri, Semp., from Sines, I used an original specimen 
which belonged to Semper. 
Cucumaria Montagu, Flem. (=le Fleurilardé, Dicquemarre, 
1778 ;=Colochirus Andersoni, Lampert, 1885 ;= Colochirus Lacazet, 
Hérouard, 1890), was represented by three quite young specimens 
measuring from 4 to § millim. in length. Jeffrey Bell (doc. ct.) has 
not recognized this conspicuous species, which also occurs on the 
coasts of Great Britain. I have set forth its synonymy at length in 
my memoir alluded to above. The examination of these young 
specimens has decided me to give a new, and perhaps finally satis- 
factory solution of the question as to what Forbes (‘A History of 
British Starfishes,’ London, 1841) understood by his ‘ Psolinus 
brevis.” The choice of the generic name proves that Forbes wished 
to draw attention to the contrast between the dorsal and ventral 
surface, which distantiy recalled Psolus. It is precisely this pecu- 
larity that distinguishes C. Montagui, and this it was also that 
misled Lampert and Hérouard, so as to make them think of Colo- 
chirus, since in the species of this genus the feet are confined to the 
ventral surface. The sole difference between the contracted young 
specimens of C. Montagwi from Sines and the figure of Psolinus 
brevis drawn from life, consists in the fact that in the former the 
feet are more numerous and are not arranged ina single row. It 
is well known that Litken referred Psolinus brevis to Cucumaria 
(Ocnus) minuta, F.—Suitzgs.-Ber. k. Akad. Wiss. Wien, math.- 
naturw. Classe, Jahrg. 1893, no. xii. pp. 107-109.

The construction of the great experimental fish-pond, recently 
added to the laboratory at Banyuls-sur-Mer, has enabled me to make 
certain observations which I had vainly endeavoured to carry out
