rhynchus, as indicated by Dr. Woodward. The differences be- 

 tween these living and fossil species are no greater than the 

 differences among the species of the genus itself. Dr. ITussakof 

 agrees with Jordan that Scapanorhynchus is closely related to 

 the Odontaspid sharks. bu1 whether it should be placed in that 

 family or constitute a distinct family must depend on further 

 studies of its anatomy. 



One of the most remarkable features in geographical distribu- 

 tion is the extraordinary number of singular animals, especially 

 sharks and chiimeras, which have been discovered in the waters 

 of Sagami Bay, the first bay to the southward of Tokyo in Japan. 



In the Mark Anniversary Volume Dr. Jacob Reighard de- 

 scribes in great detail the natural history of the bowfin, Amia 

 calva, with colored plates of different stages in the development 

 of this singular fish. 



In the Proceedings of tin Biological Society of Washington, 

 1909, Dr. Barton Warren Evermann and Edmund Lee Golds- 

 borough describe a number of fishes from the canal zone of 

 Panama. Of these. Cheirodon gorgoner, from Gorgona, is new. 



In the same Proa edings, 1909, Dr. Barton Warren Evermann 

 and John Treadwell Nicholas describe the fishes of Crab Creek, 

 in the state of Washington, and with a new species or variation 

 of trout known as Sahno < remogenes. This is a very robust 

 form, with the spots gathered on the posterior part of the body. 

 It is apparently a variant of the cut-throat trout, Sahno clarki. 



In the same Proceedings, 1909, Dr. Evermann and Lewis Rad- 

 cliffe have an interesting note on Orcstias agassizii, a singular 

 fish from Lake Titicaca. 



In the Memoirs of the Carnegie Museum, Volume 4, 1909, Dr. 

 Jordan and Robert Earl Richardson have a catalogue of the 

 fishes of the island of Formosa, or Taiwan, based on the collec- 

 tions of Dr. Hans Sauter. The fauna of this island is essen- 

 tially tropical, and intermediate between that of Japan and 



having been made among the coral reefs. In this paper nine 

 new species are described and elegantly figured. 



In the Annals of the Carnegie Museum, Volume 6, 1909, are 

 three reports of the expedition to British Guiana of the Indiana 

 University and the Carnegie Museum. This is part of the work 

 undertaken by Dr. Carl H. Eigenmann under the joint patronage 

 of the two institutions mentioned, and having in view as its
