 pi. 1; al>s. in Zool. Centbl., 5 (189? ), No. .'. p. 40). — Citto tamia avicola, n. sp., from 

 Anas sp. In the genital organs, number of testes, and position of the excretory 

 canals it is related to C. marmotie, and in the structure of the cirrus to C. pectinata. 



Notes on Trematode parasites of fishes, E. Linton (Reprint (No. 1133) from 

 Proc. U. S. Nat. Mux., 20 (ISO?), pp. 507-543, ph. 1.1). — The new species, Nitzchia 

 papulosa from Gadus callarias, Octoplectanum affine from Paralichthys dentatus, Dis-

 from Remora remora, D. foliation from Mola mola, 1). nitens from Tylosurus caribbceus, 

 D. tenue from Roccus lineatus, and 1>. tenue tenuissime from Marone americana. are 

 described. In all 32 species and subspecies are listed. The other genera represented

The Myxosporidia in the musculature of the genus Coregonus, E. Zschokke 

 (Zool. Anz., 21 (1S98), Xo. 354, pp. 213, 214). — The author is of the opinion as a result 

 of his studies that all of the Myxosporidia found in the musculature of Coregonus 

 occurring in the waters of Switzerland belong to the same species. Since none of 

 the 3 species recorded have been sufficiently described or figured the author proposes 

 to group them all as Myxobolus bicaudatus, which he describes. This species is found 

 often in large numbers iu the connective tissue of the musculature of Coregonus. 



The Arcturidae in the U. S. National Museum, J. E. Benedict (Proc. Biol. 

 Soc. Washington, 1 .' (1S9S), pp. 41-51, figs. 9). — A key to the species of the genus
