REPORT ON THE CIRRIPEDIA. 5 



of Balanus (Balanus perforatus, Bcdanus improvisus, Balanus amphitrite, and Balanus 

 balanoides), one of A casta {Acasta spjongites), one of Pyrgoma {Pyrgoma anglicum), one 

 of Coronula (Coronula biscayensis., van Beneden, which is probably the same as Coro- 

 ii ula balaenaris, Gmelin), Chthamalus stellatus, Verruca stromia ; five species of Lepas, 

 Conchoderma auritum and Conchoderma virgatum, Sccdpellum vidgare, and Pollicipes 

 cornucopia. Cailliaud observed, moreover, Alepas parasitica, Rang, as an inhabitant of 

 the French coast. With the exception of Balanus amphitrite, all these species are found 

 also on the English coast. 



The Mediterranean species are, I think, not sufficiently known. A new species of 

 Dichelaspis (Dichelaspis darwinii) was described in 1861 by F. de Filippi. 1 I received, 

 from the direction of the Zoological Station at Naples, specimens of that species, and also 

 of Lepas pectinata and anatifera, Sccdpellum vidgare, Conchoderma virgatum and 

 auritum, Alepas minuta, and Balanus perforatus. These species occur in the Gulf of 

 Naples or in its vicinity. It is likewise inhabited by Balanus amphitrite, as I know from 

 having collected it myself. Heller 2 (1866) mentions a new species of Conchoderma 

 [Conchoderma gracile), a delicate little species, occurring in the Adriatic Sea, and 

 occupying the gills of Maja squinado. The great variability, however, of the members 

 of this genus makes me hesitate before accepting this as a distinct species. He, more- 

 over, observed in the Adriatic Sea Lepas anatifera, Sccdpellum vidgare, Chthamalus 

 stellatus, and Chelonia testudinaria. The latter on Chelonia caretta. Stossich 3 (1880) 

 observed there the same species, and also Bcdanus tintinnabulum. 



P. Mayer 4 (1878) published a short notice of the occurrence of Conchoderma virgatum, 

 Spengler, on an undetermined species of Pennella, taken from Xiphias gladius, at Naples. 



According to Marcusen'" (1867), the Black Sea is inhabited by Tetraclita porosa, and 

 some species of Balanus. Czerniavski 6 (1868) mentions for the Black Sea Balanus 

 improvisus, Darwin, and an undetermined species similar to Bcdanus dccliris. 

 Darwin. 



Noll 7 (1875) described a new genus of Cirripedia, which he called Kochlorine, and 

 which was found by him near Cadiz, living in holes bored in the shells of Haliotis. 

 According to him the new genus comes near to Cryptophialus and Alcippe, and so forms 

 a third genus of the Abdominalia (Darwin). The species is called by him Kochlorine
