§ I. 1888.—In the ‘Memoirs of the Geological Survey of New South 
Wales, Palzontology,’ No. I. pp. 1-8, and plate 1, figs. 1-10, Robert 
Etheridge, junior, treating of the Invertebrate Fauna of the Hawkesbury- 
Wianametta Series of New South Wales, describes and figures some 
_ LEstherie obtained by deep borings in those strata, namely at the Moore- 
park, Port-Hacking, Dent’s Creek, Heathcote, Narrabeen, and Moorbank 
Bores. 
Estheria Coghlani, Cox, first described in the ‘ Proceedings of the 
Linnean Society of New South Wales for 1880 (1881),’ vol. v. p. 276, is 
here figured in plate 1, figs. 1-5 (from Dent’s Creek Bore) ; and some 
undetermined fragments, figs. 6, 8-10, from the same and from the Narra- 
been Bore. 
§ II. 1895-6.—In his memoir on the stratigraphic and faunal rela- 
tions of the Oneonta sandstones and shales, the Ithaca and the Portage 
groups in Central New York, from the ‘ Fifteenth Aunual Report of the 
State Geologist,’ Mr. J. M. Clarke describes, at pp. 63-81, some sections 
in Chenango, Courtland, Schuyler, and Yates Counties. At Station VI., 
De Ruyter, Madison County (pp. 68 and 69), above the Tully Limestone 
come the Sherburne Sands, and herein were found three specimens of an 
interesting species of Khinocaris, which Mr. Clarke names bipennis. 
Though not perfectly preserved, they show a low curved ridge on the 
valve, an optic and a mandibular node, three external abdominal segmenis, 
and caudal appendage. In one of the specimens a valve has been 
weathered away and exposes some obscure evidences of internal organi- 
sation. 
§ III. 1897.—In the ‘Thirteenth Report on the Paleozoic Phyllopoda’ 
(‘Report Brit. Assoc. for 1897,’ pp. 343-346) reference was made at pages 
343 and 344 to some of Dr. G. F. Matthew’s minute Cambrian fossils 
from New Brunswick. In a letter dated November 5, 1897, he directs 
attention to ‘ Leperdilla’ as misspelt for Lepidilia, and having no con- 
nection with Leperditia, but meaning ‘double scale,’ being bivalved. He 
adds: ‘TI wish to withdraw Lepidilla, as not being a crustacean. More
