Schmalensceia aniphionura en ny irilobit-typ, af JOH, Chr. Moberg. 
[Meddelanden fran Lunds Geologisk-Mineralogiska Institution, No. 
5. Stockholm, 1903.] 
Dr. Moberg states that a pecuhar and interesting trilobite was 
found in the collections of the Geological and Mineralogical Institution 
of the University of Lund labelled as "Limarssonia occulta" [Lin- 
narssonia was preoccupied by Walcott for a genus of brachiopod]. The 
fossil is stated to have been collected from the zone Agnostus pisi- 
formis — the lower part of that zone, in close relation to the equivalent 
of the Andrarum limestone, and so near the top of the Paradoxides 
beds. 
The material studied shows the principal parts of the test, the 
middle piece of the headshield the movable cheek, the pygidium and 
parts of the body joint, which is carefully described by the author. 
The dimensions of the parts also are given, and there is a plate of 
figures showing the aspect of the two shields, etc. Each of the shields 
is from 1.5 to 1.8 mm. long, and of proportionate width. 
Dr. Moberg in' conclusion refers this little trilobite to the neigh- 
borhood of the Chiruridse, but says that it does not belong to any 
known family. 
[It appears to bear the same relation of Chiruridse that Conophyrs 
does to Asaphidas or that Achantholenus does to Anomocare; i.e. 
small, immature form of a large trilobite, or a trilobite arrested in its 
development in one of its early stages. A larval feature appears in the 
narrow annulated glabella, though the closeness of the eye to the gla- 
bella has an opposite meaning. In any case the trilobite is of interest 
as carrying down to the base of the Upper Cambrian a type hitherto 
known only from the summit of the Cambrian, upwards.] g. f. m. 
The Glacial Geology of Nezu Jersey. By Rollin D. Salisbury ; assist-

V of the Final Report, Geol. Survey of New Jersey; Henry B.

In New Jersey the central part of the great ice-lobe of New York 
and New England attained its farthest southward extension, lacking 
only about 200 miles of the lowest latitude reached by the ice boundary 
in southern Illinois, at the central and farthest advance of its wider 
compound lobe in the Mississippi basin. New Jersey is also of great 
interest to glacialists because there the varied deposits of the glacial 
drift adjoin the Pleistocene formations of the more southern part of
