been studied under the microscope and classified. Among the 

 igneous rocks, granites, diorites, gabbros and several porphyries, 

 with effusives of rhyolite, andesite and basalt, are the ruling types, 

 and it is interesting to note that no rocks of pronounced alkalic 

 nature were encountered. The work is of a purely descriptive 

 character, and as no summation or generalizations of the observed 

 facts are given, it is inferred that these are reserved for that part 

 of the work dealing with the general geology of the region visited. 



Of the zoological material gathered by Mr. Blackwelder, the 

 description of the reptiles and birds is given by himself with the 

 assistance of Drs. Stejneger and C. W. Richmond. Of the Reptilia 

 only a few specimens were obtained, consisting of several lizards 

 and one snake, of already described species. The Birds are rep- 

 resented, however, by a larger collection of 64 specimens contain- 

 ing 49 species. Most of these are naturally of small kinds, larks, 

 finches, sparrows, wrens, thrushes, etc. While none of the speci- 

 mens proved to be of an absolutely new species, an interesting 

 new variety of the Chi-li winter wren was obtained — Olbiorchilus 

 fumigatus ideus Richmond. This part of the text is embellished 

 by several fine colored plates of the birds collected. 



The volume concludes with a syllabary for the transcription of 

 Chinese sounds in the dialect of Peking, modified for literary 

 purposes by Dr. Friedrich Hirth of Columbia University.

3. Miscellanea Ealceontologica; von Prof. Dr. Anton Fritsch. 

 1. Palceozoica. Pp. 23, pits. 12. Published by the author, Prag, 

 Bohemia, 1907. — In this quarto paper the author describes and 

 illustrates seventeen invertebrate Paleozoic animal remains. 

 Among them are discussions of several American species, as fol- 

 lows: JProscorpia osborni, JPalceocampa anthrax (gives also a 

 restoration of this Polechset worm; states that it is not a Myria- 

 pod), Propolynoe laccoei (a new genus and species of annelid 

 from Mazon Creek, Indiana), Hesionites bioculata (Ch.setopod 

 from Mazon Creek), Latzelia primordialis (the oldest Chilopod 

 and related to the recent genus Scutigera). 



There is also described a new Camerocrinus quarzitarum, ex- 

 tending the range of these extraordinary crinoid floats to the 

 Ordovician (etage Dd2). The balance of the work is devoted 

 to a description of the Permian Coprolites of Bohemia (26 species!).

4. Evidences of a Cohlenzian invasion in theDevonic of Eastern 

 America- by John M. Clarke. Festschrift zum siebzigsten 

 Geburtstage von Adolf v. Koenen, pp. 359-368, Stuttgart, 1907. 

 — In this short paper the author gives his views in regard to the 

 relation of the Helderbergian and Oriskanian and the probable 

 waterways of migration of the faunas about Gaspe, Quebec, Dal- 

 housie, New Brunswick, and localities in Maine. It is in the 

 latter region that marked Coblenzian affinities are shown in the 

 faunas. c. s.
