ters of the valves and internal supports leads our authority to 
place Pentamerus and Porambonites in the same family Poram- 
bonitide. The genus Porambonites leads upwards towards the 
Strophomenidz, while Pentamerus points towards the Rhyn- 
chonellidz. 
Devonian—E. Kayser (Zeit. Deut. Geol. Gesell., 1883) de- 
scribes two new goniatites and four new brachiopods from the 
Devonian of the Rhine. 
Carboniferous—In the Geological Magazine, Dec., 1883, Mr- 
H. Woodward continues his synopsis of the genera and species 
of carboniferous trilobites, characterizing four species of Brachy- 
metopus, one of which is new. The same writer has also some 
notes on the nature of the two pits, or pores, placed one on each 
side of the glabella, in front of the compound eyes. He inclines 
. Somewhat to the belief that they may, as suggested by Mr. J. 
Young, be the marks of ocelli, such as occur in the Merostomata, 
both recent and fossil. If so, this would be further evidence of 
the affinities of both groups with the Arachnida. The pore is, 
owever, present in the isopodous genera Sphzroma and Serolis, 
as well as in Limulus. 
Permian.—H. Credner (Zeit. Deut. Geol. Gesell., 1883) con- 
tributes a fourth article upon the Stegocephali of the Rothlie- 
genden near Dresden. Branchiosaurus gracilis, Acanthostoma 
vorax, Melanerpeton spiniceps and Discosaurus permianus are de- 
scribed. The last belongs to the family Limnerpetidez. 
Mesozoic —Emil Haug (Neues Jahrb. fiir Min., Geol. und Pal.) 
reviews the so-called Chztetes of the Mesozoic strata. Of these 
he describes Monticulipora recubariensis from the Trias; Chetetes 
beneckei, a true Cheetetes, from the gray limestone of the Lias of 
rn Tyrol, and Pseudochetetes polyporus. 
ertiary——The ninth volume of the Memoirs of the Swiss. 
Paleontological Society contains a report upon the chelonians 
the Vaudois molasse preserved in the Museum of Lausanne 
by Dr. Portis. Three new species of Emys, one of Kinosternon, 
one of Cistudo, three of Trionyx are described, and a list of twen- 
ty-five species is given. In an appendix the same writer de- 
| e new genus and species Polysternon provinciale from the 
peer Cretaceous of Fuveau. The plastron of this species is pecu- 
| from the presence of a pair of osseous plates between the hypo- 
ns, which are very much shortened, and the xiphi-plas- 
trons. These are styled by Portis prosteto-plastrons. The mem- 
Bor illustrated by twenty-nine plates.—Dr. Lemoine describes 
Ah Species of Adapisorex, distinguished by the variable dimen- 
Te of the maxillaries and the well characterized form of the 
ee mar. These are A. gaudryii, chevilionti, remensis and 
tric mus. All are of very small size and, as signified by the gen- 
name, have affinities with the Tertiary Adapis on the one
