how our knowledge of the Gotland Cephalopoda has increased.

large O. with smooth surface, not unlike O. communis.) O. angulatus W., O. imbri- 
catus, O. crassiventris. Orth. undulatus (= OO. annulatus Sow.) is for the first time 
described in this paper. All these species are again enumerated on page 333 and in 
the table, but are there called Orthocera communis, imbricata, angulata, undulata 
n. Sp., crassiventris. 
Bidrag till Sveriges Geognosie, part 4, (also called »Anteckningar i Physik och Geo-

the preceeding. OO. imbricatus is, however, by him identified with O. undulatus Sow. 
Min. Conch. tab. 59 and O. crassiventris with O. cochleatus. A new species is by 
HISINGER referred to O. annulatus Sow. t. 133, but this, however, is identical with 
HIsSINGER's O. undulatus, and O. annulatus His. has later by Borr been named O. 
Hisingeri. In this publication thus six species are enumerated.

We thus have nine species of which three are mentioned for the first time.

with addition of lithographed figures of nearly all species. Önly O. lineatus has been 
changed into »Scyphia empleura MÖNSTER» and thus translated to the sponges.

This was the first instalment of the next work and contained only ten plates without 
any descriptions. Seven species of Upper Silurian Cephalopoda are figured.
