WALCOTT, Charles D.— Continued. 



In this paper Doctor Walfott continues bin 

 studies of Cambrian bracliiopoda. He (Ic- 

 lints the genus AcmtreUi, 21 new species or 

 new varieties and 12 old sjiecies; the new 

 genus Linnarsonclla, with 2 new and 1 previ- 

 ously described species; Brnggeria, a new sub- 

 genus of Ohnlus, with 1 species. Of Lin- 

 gulella 4. new and 4 old species are described, 

 and of Westonia 1 new species. 



WHITE, David. Description of a fossil 

 alga from the Chemung of New York, 

 with remarks on the genus HaUserites 

 Sternberg. 



Bull. N. Y. State Museum, No. 52, 1901, 

 1902, pp. 696-610, pis. 3, 4. 

 The principal specimens described in this 

 paper, which was published in the Report of 

 the State Paleontologist, are from the Che- 

 mungstrataof East Windsor, Broome County, 

 N. Y.,and are referred to a new genus, Tham- 

 nodadus, and are named Thamnodadus 

 darkei. The new genus i.s differentiated from 

 Buthoireplm, Psilophyton, and HaUserites, to 

 the latter of which specimens of the new 

 genus have hitherto been referred. The 

 name Txniocrada is proposed for the mem- 

 branaceous algoid plant conforming to the 

 genus HaUserites as defined by Penhallow. 

 The type species is said to be Tivniocrada 

 lesqiiereuxii, formerly illustrated as HaUserites 

 dechenianvs.

 In addition to an account of the life of 

 R. D. Lacoe, a bibliography is given and ref- 

 erence made to the collections donated by 

 him to the U. S. National Museum. These 

 collections embraced about 17,000 Paleozoic 

 plant fossils, including over 675 described or 

 figured specimens; 800 Dakota plants, includ- 

 ing a large number of types; nearly 5,000 

 specimens of fossil insects, of which over 200 

 are types; 400 specimens of fossil vertebrates; 

 a large amount of unpublished plant mate- 

 rial, and several thousands of insects partially 

 reported on by Doctor Scudder. 



WILSON, Charles Branch. North 

 American parasitic copepods of the 

 family Argulidpe, with a bibliography 

 of the group and a systematic review 

 of all known species. 



Proc. U. S. Nut. Mus., xxv. No. 1302, Nov. 

 25, 1902, pp. 635-742, pis. Vlll-xxvil, 23 

 text figs. 

 A comprehensive report on the Argulidse, 

 comprising a historical sketch, bibliography, 

 an account of their ecology, ontogeny, and 

 morphology, and a systematic review of the 

 species. The following species are described 

 as new : Argulus niger, A. maculosus, A. versi- 

 color, A. americanus. 



The following references to papers by Dr. Theodore Gill, published between Sep- 

 tember, 1899, and May, 1902, were not furnished in time to be included with tlie 

 bibliographies accompanying the reports for those j'ears, and are therefore printed 

 in connection with the Museum Inbliography for 1903, at his request. 



GILL, Theodore. Desirability of exten- 

 sion of study of eggs. (Editorial. ) 

 Osprey, iv, No. 1, Sept., 1899, pp. 9-10. 

 The desirability of extending the .study of 

 eggs beyond their shells is urged. The in- 

 vestigations of Valenciennes and Fremy on 

 the contents of the egg, published in 1854, are 

 referred to, and the difference between the 

 reaction to boiling is indicated in the case of 

 the albumen of the Lapwing. Data are asked 

 for as "to the absolute and relative time re- 

 quired by the white and yellow to become 

 hard in boiling, the degree of hardness ac- 

 quired, and the behavior of white and yellow 

 to reagents." It is also added that "the edi- 

 bility and taste of eggs of different kinds would 

 also be interesting subj ects for investigation ." 



Popular ignorance of birds. (Ed- 

 itorial. ) 



Osprey, IV, No. 3, Nov., 1899, pp. 43-44. 

 The wide publication of a note on "A bird 

 with a monkey face" is taken as the text of 

 an editorial on the general ignorance of com- 

 mon birds. The bird in question was a com- 

 mon Barn Owl. 



GILL, Theodore. The largest birds, 

 (pjditorial.) 



Osprey, iv. No. 4, Dec, 1899, pp. 57-59. 

 The opinion of J. E. Harting that the Dinor- 

 'iiis miLtimus was "the largest known bird 

 that had ever lived" is noted. The Ttirasae- 

 tus harpyia, or Harpy Eagle, is declared to be 

 apparently the largest bird of prey, weighing 

 28 to 30 pounds. Attention is called to the 

 overlooked fact that the common Turkey 

 may be "the largest bird that flies," as it 

 sometimes may exceptionally attain a weight 

 of 70 pounds. Such a turkey, however, could 

 scarcely fly. 



Esthetic ])irds: The Bower P.irds 



of Australia and New Guinea. 



Osprey, IV, No. 4, Jan., 1900, pp. 67-71. 

 A summary of the knowledge acqtiired re- 

 specting the nesting habits of the Bower 

 Birds, or Ptilonorhynchinse, is given and the 

 "bowers and playing grounds" as well as 

 "nests and eggs" of species described and 

 illustrated by 3 figures representing the 

 Satin Bower Bird and its nest and eggs, as 

 well as the Bower of the (jreat Bower Bird.
