the Atlantic Occau II. ForsTccdii does not attain so large a size as in 

 the ilediterranean. 



Cucumaria Koellikeri, Semp., hitherto known only from Sicily 

 and Xaples, has likewise under another name figured for some time 

 past as a member of the Holothurian fauna of the Atlantic. I re- 

 gard Oucumaria Lefevrii, Th. Barrois (18S2), 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 Herouard (" Eecherohes 

 sur les Holothuries des cotes de France," Arch. Zool. Exp. [2] 

 vol. vii. 1890) in regarding Cucunutria Lefeurii, with ten tentacles, 

 as synonymous with Thompson's old species C. Drv.mondii, which 

 is now assigned to the genus PhyUophorus. Since I have in the 

 meantime learned to know the species, I can now also protest 

 afrainst Herouard'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 Montagui. Flem. ( = le Fleurilarde, Dicquemarre, 

 1778 •, = Coloc7iirus Andersoni, Lampert, 1885 ;=Colochirus Lacctzei, 

 Herouard, 1890), was represented by three quite young specimens 

 measuring from 4 to 8 millim. in length. Jeffrey Bell (loc. cit.) 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, 18-il) uuderstood by his " Fsolinus 

 brevis." The choice of the generic name proves that Forbes wished 

 to draw attention to the contrast between the dorsal and ventral 

 surface, which distantly recalled Psolus. It is precisely this pecu- 

 liarity that distinguishes C. Montagui, and this it was also that 

 Biisled Lampert and Herouard, 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. Montagui from Sines and the figure of PsoUnus 

 hrcvis drawn from life, consists in the f;ict that in the former the 

 feet are more numerous and are not arranged in a single row. It 

 is well known that Liitken referred PsoUnus brevis to Cucumaria 

 (Ocnus) minuta, F. — Sitzgs.-Ber. Tc. Alad. Wiss. Wien^ mat/i.- 

 miturw. 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 



' The observations here described were made at the zoological labora- 

 tory at Bauyuls-sur-Mur (Pyruuet'S Urieutales).
