Notes on Recent Fish Literature.— Mr. C. Tate Regan, of the 
British Museum, continues his varied series of fish studies bya 
number of short papers in the Annals and Magazine of Natural His- 
tory. One of these, “The Phylogeny of the Teleostomi" (May, 
1904), must challenge the attention of all palzontologists by its bold 
theory that the chondrostean ganoids (Paleoniscum, Acipenser, 
Polyodon, etc.) are the most primitive of teleostomous fishes, and 
that they have given rise to the crossopterygians and dipnoans as 
well as to the ostracophores, arthrodires, and teleosts. After sepa- 
rating the still more primitive sharks, Mr. Regan divides the other 
fishes into five orders, Chondrostei, Crossopterygii, Placodermi, Dip- 
neusti, and Teleostei. The Teleostei | have sprung, in his scheme,
