if Meristella be retained then either Athyris. or  Spirigera must be suppressed in 
order to make a vacancy for it, There is no probability of this being agreed to o by 
palzontologists. The other genus Merista will no doubt hold good for those species 
which have the shoe-lifter process in the ventral valve 
Prof. Hall describes a new genus of Crinoids under the name of 
heirocrinus, and also proposes two new genera of trilobites Barrandia 
and Bathynotus to include the peculiar forms from Vermont heretofore 
erred by him to the genus Olenus. It has perhaps secant Mr. Hall’s 
notice that McCoy has published a trilobite genus “ gaat in 
the “ British Paleeozoic Fossils,” p- 149. McCoy’ $ genus appears 
isputed but still it must be retained until it is clearly shown ie be 
without foundation 
3. Geological hie ys.—Trnnesser. Prof. Safford is now publish- 
ing the first volume of his Report on this State. It will be in two 
rts. Ist. The Physical Geography of Tennessee, 2d. The Geological 
Structure and the Formations of Tennessee, It is in 8vo, and will con- 
tain a map of the State and 20 or 30 plates, chiefly fossils. Its comple- 
tion is expected in about three months. A second volume to be published 
hereafter, contain Part 3d, the Minerals and mineral resources 0 the 
State, and Part 4th, the Agricultural resources. 
Kenttcxy.—The publication of the fourth and concluding volume af 
this Survey is in the hands of Dr. Robert Peter, of Lexington, Ky. The 
matter will form a large and very valuable volume. ‘The ‘Legislature 
ordered 7000 copies to be printed. The completion of the work may be 
expected during the coming summer, if political causes do not arrest
