Types die Prodrome de Pal'eontologie stratigraphique univer- 

 selle de d' Orbigny. Pp. L-4, pis. 1, 2 (incomplete). — The origi- 

 nal very brief descriptions of d'Orbigny are here republished 

 with short observations by A. Thevenin ; no attempt, however, 

 is made to indicate the present name for these fossils. The illus- 

 trations are of much value, as they are photographs of the origi- 

 nals. At least five of the species figured are American Paleozoic 

 forms. Remarks on these are reserved until the work is com- 

 pleted, c. s. 



3. Arthrophycus and Dazdalus of Burrow Origin, and Pre- 

 liminary Note on the Nature of Taonurus ; by Clifton J. 

 Sarle. Proc. Rochester Acad. Sci., iv, Feb., 1906, pp. 203-214. 

 — The first article treats of the supposed fucoids usually known 

 as Arthrophycus. An elaborate study has been made of a very 

 extensive series of well-preserved specimens found in the Medina 

 sandstones about Rochester, New York. From these researches, 

 the author concludes that these bodies are not organic, but are 

 the burrows of an animal, possibly a polychsete worm. These 

 burrows and packings may be nearly horizontal with the sedimen- 

 tation or vertically spiral either to the right or left. The generic 

 term Arthrophycus is retained for the plumose forms found on 

 the bedding planes, and Daidalus for the spiral burrows. 



Taonurus treats of very similar burrows known to Americans 

 as Spirophyton, and usually regarded as fucoid. These fossils 

 are common in the eastern Hamilton formation and are undoubt- 

 edly made in the same general way as are Arthrophycus and 

 Pmdalus. The evidence and deductions on which the author 

 bases these conclusions can not be presented here, and must be 

 read in detail in order to appreciate these by no means simple 

 fossils. c. s. 



4. Echinoderma ; by F. A. Bather. Zool. Rec, xli, Dec, 

 1905, 96 pp. — This valuable annual record of the literature of 

 Echinoderma, for 1904, continues the high standard set by the 

 author. It lists 103 titles, and notes the contents of these papers 

 in detail. 



5. The Osteology of Champsosaurus Cope : by Barntjm 

 Brown. Mem. Amer. Mus. Nat. Hist., ix, Dec, 1905, pp. 1-26, 

 pis. i-v. — This memoir gives a detailed description of three more or 

 less complete skeletons of the semiaquatic rhynchocephaloid rep- 

 tile Champsosaurus from the lower strata of the lignite above 

 the Ceratops beds of the Laramie, as exposed on Hell Creek, 130 

 miles northwest of Miles City, Montana. The material has been 

 well worked out, and the memoir is handsomely illustrated by 

 heliotype plates made in Germany.
