4 INK VOYAGE OF II. M.S. CHALLENGER. 



Matotsjkin-Shar (Nowaja-Zemlja) (Hoek), 1 &c. Balanus balanoides, Linn., was collected 

 near Port Foulke, Arctic America (Miers), 2 and in the Matotsjkin-Shar (Hoek) ; Balanus 

 crenatus, Brug., finally, occurs in Discovery Bay, Greenland, in 30 fathoms (Miers). 



The species of Cirripedia occurring at the coast of Bohuslan are enumerated by 

 A. \Y. Malm 3 : they are of the non-parasitic species, three species of Balanus, Verruca 

 stromia, Lifts anatifera, Lepas hillii, and Lepas fascicular is, Conchoderma virgatum, 

 and Aucfasma sqniilicola. 



The Cirripedia of the Baltic belong all to the genus Balanus. According to Prof. 

 Mobius 4 they are Balanus crenatus, Balanus porcatus, and Balanus improvisus. The 

 latter was observed in 1868, in the brackish water of the Byk River, by Prof. Julius 

 Miinter, 6 and is found, moreover, at several points on the northern shores of Germany 

 (Metzger). 6 



The Cirripedia of the German coast are not very numerous. Metzger 7 (1870) only 

 mentions Balanus porcatus, Balanus crenatus, and Balanus balanoides, Verruca stromia, 

 Lepas anatifera, and Lepas anserifera. Clithamalus stellatus, Poli, sp, is found near 

 Heligoland, as was observed by me in 1877. Frey and Leuckart 8 (1847) described two 

 new species of the same genus from the coast of Heligoland, but they are no doubt 

 varieties of the species named above. 



A list of the species found on the Dutch coast was published by me 9 in 1876. I 

 observed only four species of Balanus, Lepas anatifera, and Verruca stromia. For the 

 Belgian coast P. J. van Beneden 10 (1861) mentions only Lepas anatifera and a species of 

 Balanus. 



Of the Cirripedia of the French coast we possess lists published by Caillaud u 

 (1865) and by Fischer 12 (1872). The latter enumerates eighteen different species : — four
