of Indiana. The lower part of the Niagara group, in Indiana, is char- 
acterized by the presence of the remains of cystideans; while the upper 
part abounds with crinoids, brachiopods, bryozoa and other fossils." 
Most of the cystideans belong to the very variable genus HolocyHtites. 
It is stated as a fact worthy of note that half of all the species of cysti- 
deans known from America occur in the Hudson River and Niagara 
groups of Indiana. There are remarks on the scientific value of fossils 
and on rules for nomenclature. 
Of the fossils described there are three species of sponges, and from the 
head lines it would appear that Mr. Miller stands with Saville-Kent, in op 
position to the views of a majority of competent zoologists, in referring 
sponges to the sub-kingdom Protozoa. There are twelve species of 
corals, one of which, the Lcptoporn yorhyi, n. s., is doubtfully referred 
to the Tabulata. Seventy-eight species belong to the Eddnodennatti , 
mostly cystideans and crinoids. Of the genus Jlolocystites alone 
there are fifteen species. 
Among the echinodermata the following new genera are proposed: — 
Strihalocystites, Zophocrinus and Bldirocrinaa. Among sponges there is 
one new genus, Cydospongiu. 
The remaining genera and species embrace a few species of brachiop- 
oda, one Conularia and a number of molluscs. The Pleurotomaria Jiarii, 
page 88, Plate XIV., Figs. 8 and 4, might properly and profitably have 
been compared with 7*. nrrhonarid, N. and P., and P. nrwportfinKis White. 
Second Annual Report of the Geological Si/rcey of Texas, 18'J0, E. T. 
DuMBLE, F, G. S. A. State Geologist. Carhoniferoun Cephalopods. By 
Alphel's Hyatt. The paper on Carboniferous cephalopods by professor 
Hyatt embraces pages 829 to 8.30 inclusive, in the Second Annual Report 
of the Geological Survey of Texas. The forms described were collected 
in part by the Geological Survey of Texas, part belong to the National 
Museum, and a few belong to private individuals whose names are 
given in connection with the specific descriptions. The genera represen- 
ted are divided between the XautUoidea and doniatitina'. To the first 
group belong Temnocheihis, represented by five species; Mitacoceras, by 
five species; Tainoce rag, one species; Domatoceras, a new genus to which 
is referred one species; Asymtoceran, one species; Phacocerax, one; 
EphippioreraH, one; and Endolobns, one. To the Goniatitina* belongs the 
genus (rastrioceras which is represented by the new species G. couipret^- 
sum. As stated in the pre factory note the paper comprisesa larger num-. 
ber of species of Carboniferus cephalopods than had previously been 
got together in a single publication. Excellent outline figures ac- 
company the descriptions. 
In, the Second Annual Report of the Geological Surrey of I'cvas, page 5.52, 
professor W. F. Cummins describes a very beautiful and interesting little 
coral from the Carljoniferous strata of Texas, under the name, Jladm- 
phylluni apdatus. II. apAatua is certainlj' very closely related generically to 
MicrorycluH discus Meek and Worthen, and it is possible that this last 
species will have to be referred to Ilaftro/diyllum. Six good figures 
illustrate Prof. Cummins' species.
