REPORT ON THE CIRRIPEDIA. 9 



species of Chthamalus, one of Verruca, one of Scalpellum, and three of Pollicipes 

 {Mitella, Oken, as Bosquet calls the genus), moreover, short notes about .some species, 

 descriptions of which were published by Darwin or by Bosquet in his Crustacea fossiles 

 du terrain (-ret, ice du Duche* de Limbourg, 1853. The most interesting feature of the 

 new publication of Bosquet is, in the first place, that Chthamalus is shown to occur 

 in the Chalk of the Maestricht Formation, — the first instance of a true Balanid in 

 secondary formations, if, with Darwin, we consider Verruca as a representative of a 

 distinct family. In the second place, that a second species of Verruca, was added to the 

 only one known as occurring in secondary deposits. 



In two different papers (18G1 and 1864) Reuss 1 has largely increased our knowledge 

 with regard to the fossil Lepadids. He has described two new species of Scalpellum from 

 Tertiary deposits of the Oligocene formation of Sollingen near Crefeld, one new 

 Pollicipes and one new Pascilasma of the same Tertiary stage. The latter is represented 

 by a single valve, which, being symmetrical, is considered as a carina; of course, the 

 di 'termination of Reuss may be correct, but as this would be the first instance of a 

 Lepadkl nearly related to Lepas being found in a Tertiary deposit, I think w r ehad better 

 not take it into consideration for the present. We ought to act in the same way with 

 regard to the single valve which represents — according to Reuss— another species of 

 Pcecilasma and was found in the Miocene Leitha-chalk of Podjarkow in Galicia. In 

 these Miocene deposits Reuss observed, moreover, two species of Pollicipes and one of 

 Scalpellum. Finally, the same author enumerates some forms from the Bohemian 

 Cretaceous formation (two species of Pollicipes and one of Scalpellum), and three Pollicipes 

 from the Mucronate Chalk of Nagorrani. One of the latter species is new. 



Conrad" (1865) was only acquainted with two Cirripedia in the Eocene deposits of 

 North America, viz., Balanus humilis, Conr., and peregrinus, Mort. Seeley 3 (1870) 

 proposed a new species and a new genus for a scutum and a tergum of a sessile Cirriped 

 found among some Lias fossils obtained at Lyme Regis. As far as the shape and 

 the articulation are concerned, the valves resemble those of the Balanidse, though the 

 former do not display the muscular scars which distinguish the latter ; in this respect 

 they resemble the Verrucidse. For these various reasons the author is inclined to regard 

 the specimen as the type of a new family, intermediate between the Balanidse and 

 Verrucidse. The species is called Zoocapsa dolichoramphia. I need hardly say that I 

 do not wish to follow the author in his reasoning on this topic. 



In 1878, Dames 4 made the very interesting discovery of a second species of Loricvla
