Palceoiilologiska notiser, af Geehard Holm. Geol. Foren. i Stock- 
holm Forhandl. Bd. 19, Hft. 3, 1897. In some palaeontological notes by 
Dr. Gerhard Hohn we find notice of the occurrence of the rare and pe- 
culiar fossil Toi-rellella kevigafa Lnrs., at a new locality in Sweden. 
Torre llella is separated from the Hijolithidce because of its phosphatic 
shell, and this shell, like that of the Conukiriidce, eeems to have been 
exceedingly thin, for Holm says that the shell flattened in slate has only 
the thickness of paper. 
Incidentally it is spoken of as connecting more closely the subfaunas 
of Olenelliis {Holmia) kjerulfi and Oleuellus (ScJiinidtia) niichioitzi. 
Holm discusses the relation of the two Olenelli above named and 
Olenellus iMesoaacin) I'eriiiontaua and says that F. Schmidt's latest 
note on O. micliwltzi shows that he finds it more closely related in pleu- 
ra and pygidium to O. kjerulfi than he had at first thought. In the 
form of the glabella, however, to which Holm does not refer, there is a 
fundamental difference. 
A second note by Dr. Holm describes the ectosiphon of a species of 
E udoceras (E. burchardii Dewitz). The species appears to have been 
described from drift fragments found in Germany, and so belongs to the 
Swedish Ordovician rocks. Dr. Holm says it agrees perfectly with A . 
Hyatt's group Ellipochoanoida. The article is illustrated with two 
cuts of examples of E. burchardii from the island of Oeland, and a fig- 
ure of a fossil referred to the genus E udoceras [subgen. Succoceras) from 
Dalarna is also given. g. f. m. 
Palaeozoic FoshUn, Vol. Ill, Part III, 4. Tim Fossils of the Gale- 
na-Trenton and Black River formations of lake Winnipeg and its vi- 
cinity. By J. F. Whiteaves. (Pp. 129-242, pis. 16-22, Ottawa, April, 
1897.) The geology of lake Winnipeg and its vicinity has invited the 
attention of numerous explorers. The extensive collections made with- 
in recent years in that region by Dr. R. Bell, Messrs. T. C. Weston and 
L. H. Lambe, and the investigations of. Messrs. Tyrrell and Dowling 
have brought to light the richness and beauty of the Lower Silurian fau- 
nas there preserved, and in the scientific portrayal of these. Dr. Whit- 
eaves renders profound service to his science. In the last number of 
this volume of the Palceozoie Fossils the author gave a systematic list of 
all the species from the Hudson River formation of this region, and the 
present paper supplements this list with a similar one of all the other 
known species of the Lower Silurian in the lake Winnipeg district with 
the exception of certain stroraatoporoids. The horizons especially rep- 
resented are the entire Utica and Trenton formations inclusive of the 
Galena. A noteworthy feature of these faunas is the remarkable size 
attained by many of their species, a peculiarity which seems to be shar- 
ed by all classes, if somewhat more strikingly exemplified in the Cephal- 
opoda. The author cites Reeeptaculites oweni as attaining a diameter 
of 12-20 inches; Streptelasma robastum, 7 inches in length; the brach- 
iopod, Raflnesquina lata, 'iiinchea along the hinge; Maclurea, %}4, in- 
ches in diameter and Honnotonia, 8 inches long; Endoceras subannuhi- 
tum, 6 feet long and broken at both ends; Poterioceras, 7 inches in di-
