Eastman does not believe that dipnoans are descended from Crossop- 

 terygians, but rather that they may have come from the Pleuracanthus- 

 like sharks. The association of the Arthrodires with the Dipneusti, 

 finally disposes of the grouj) of Placodermata, in which the Arthro- 

 dires were nssix iated with the Ostracophores. 



In the Bullriin <./ thr Vnirrr.^ify of Montana, Dr. James A. Hen- 

 shall gives a Hst of the scant fish fauna of Montana, 36 species being 

 represented, with notes on the game fishes represented or introduced 

 into the State. 



In the Hawaiian Forester (vol. 2, 1905), Mr. Alvin Scale gives an 

 account of the successful introduction from Galveston to Honolulu 

 of three species of mosquito-eating killifishes. These are Molli- 

 nesia latipinna, Fundulus grandu, and Gamhusia afpnis. These 

 fishes w^ere received in fine condition, and they have shown great 

 avidity in freeing Hawaii of her worst insect pest. 



In the American Journal of Physiology, 1905, Professor G. H. 

 Parker discusses the stimulation of the integumentary nerves of 

 fishes by light. The sensitiveness to light of the vertebrate skin is 

 established. This trait may have served as a basis from which the 

 retinal structures and the temperature sense were derived. 



In the Marine Biological Association Report (vol. 1, 1903), are 

 elaborate studies of the Plaice, Pleuronectes platessa. Dr. William 

 Wallace has investigated the growth rate of the species. Walter 

 Garstang reports on the topographical distribution of the s[>ecies. 

 A number of studies on the natural history of the Plaice are reeoi-ded 

 in German by Mr. Garstang in Rapports du Conscil I ntn-utit'mntil 

 pour VExploration de la Mer, 1905.
