Jurian.—In a specimen of Asaphus, from the Black Trenton 
Limestone, Dr. Hy. Woodward has discovered what he believes 
to be the jointed palpus of one of the maxillz, in the same posi- 
tion as is occupied by that organ in Apus, Serolis, etc. There 
a to be seven articulations in the palpus above the basal 
joint. He states his opinion that the trilobites should be placed 
near to, if not actually in, the Isopoda-Normalia (Geol. Mag., 
Feb). Dr. I. Mickleborough follows this with an account of a 
Specimen of Asaphus megistos, in which ten pairs of jointed limbs 
are clearly seen. Dr. Reusch, in a volume recently published 
at Leipzig, describes the Silurian fossils found by him in highly 
altered rocks in the Bergen peninsula, Norway. The shells of 
the fossils have disappeared, and only a reddish colored earth 
remains; yet the trilobites, Phacops and Calymene, and the corals, 
aim Halysites, etc., with some graptolites, can be

Triassic—Herr H. Kunisch describes and figures (Zeit. der 
Deutsch. Geol. Ges., 1883) the adult stage of Æncrinus gracilis 
the Muschelkalk; and in a succeeding paper, Herr K. 
me describes and figures Excrinus Beyrichii, a new species from 
Muschelkalk, near Sondershausen. All the joints of the 
~ are pentagonal.—At a recent meeting of the Geological 
ciety of London, Professor Owen described the skull and den- 
tition of Tritylodon longevus, from South Africa. The teeth re- 
semble those of Microlestes, from the Keuper of Wirtemberg, and 
se of Stereognathus, from the Oédlite.
