PRELIMINARY OBSERVATIONS. 5 
Daniel Sharpe’s, Mr. Salter’s, and my own observations on the examination we made of 
Linneus’ original types, now in the possession of the Linnean Society of London ; for, 
as is well known, Linneus’ private collection, his manuscripts, and three interleaved 
copies of the ‘Systema Nature,’ were long ago transmitted to England. “ ‘The original 
specimens, where large enough, had been inscribed by Linneus, either with their names or 
with numerals corresponding to their position in his ‘Systema;’ the smaller ones had 
been deposited in tin boxes, marked in a like manner ; oftentimes, indeed, the numerals 
were written on both shells and boxes.” But I shall in the sequel have to again refer to the 
Jinnean species, and consequently need not now enlarge upon the subject. 
Witnertm Histverr is the next Swede to whom we would refer. In the “ Minero- 
graphisk Anmarkningar 6fver Gotland,” in the ‘ Kongliga Vetenskaps-Akademiens Hand- 
lingar’ (“ Mineralogical Notes on the Isle of Gothland,” in the ‘ Transactions of the Swedish 
Royal Academy of Sciences in Stockholm’), at p. 285, he enumerates six species of Brachio- 
poda under the name of Anoma, viz., A. pecten, A. plicatella, A. lacunosa ; but his other 
three so-termed Anomia,—A. farcta, A. gryphus, and A. hysterita, would not, according 
to Linnzus’ original specimens, be Silurian forms (see Hanley’s ‘Ipsa Linnei Con- 
chylia’). The ‘Kongl. Vet.-Ak. Handl.,” 1802 and 1804, contain his mineralogical 
descriptions of the Isle of Oeland and of the Province of Dalecarlia without any notice 
of Silurian fossils. In 1825, in his ‘Description of some Silurian Fossils from 
Humlenas, in the district of Calmar,’ he mentions 4. pecten. In 1826 ina ‘Treatise 
on the Geology of the Island of Gothland,’ p. 311, the same author enumerates eighteen 
“Terebratulee,’’ and for the first time gives figures of his new species Zerebratula crispa (not 
of Linneus), 7" bidentata, T. cardiospermiformis (—=Orthis biloba). In 1828, in the fourth 
volume of his ‘ Anteckningar uti Physik och Geognosi under resor uti Sverige och Norrige ’ 
(= ‘ Annotations in Physics and Geognosy during travels in Sweden and Norway’), and 
which is also called ‘Bedrag till Sveriges Geognosi’ (‘Contributions towards the 
Geology of Sweden), he gives figures, without descriptions, of the following species, 
Leptena euglypha, Dal., Cyrtia trapezoidales, Wisinger, Gypidia conchidium, Delthyris car- 
diospermiformis, His., Delth. crispa, His., Atrypa prunum, Dal., Terebratula cuneata, Dal., 
T. bidentata, His. In 1831, in the fifth volume of ‘ Anteckningar, &c.,’ p. 105, he describes 
the Lower Silurian Atrypa dorsata with figure (? Orthis deformata); at p. 117, &c., are 
enumerated thirty-three species of Upper Silurian Brachiopoda of Gothland, but which had 
almost all been already described by Dalman, in 1827. There are, nevertheless, the follow- 
ing new forms—Orthis pusilla (= Spirigerina pusilla, Lindst., or Atrypa disparialis, 
Hall) ; Delthyris sulcata, His. (= Anomia crispa, Linneus); Delthyris? pusio, His. ; 
Atrypa reticularis, var. B, alata, Atr. aspera, Schlotherm, being by Hisinger considered 
only as a variety of Atr. reticularis ; Atr. tumidula, His. In his ‘ Esquisse d’un Tableau 
des Pétrifications de la Suede,’ a list of the already described species is given; and in 
vol. vi of ‘Anteckningar,’ p. 8, he briefly describes Orthis argentea and Atrypa nitens
