THE AMERICAX NATURALIST. [Vol. XXXVIII. 



William C. Kendall gives a useful list of the certain river-fishes of 

 Maine. Leuciscus carletoni, a new species, with a barbel, and there- 

 fore better referred to Couesius, is described as also Pimephaks amili 

 (named for Edgar E. Ring) and Coregonus statileyi. 



In the Revista Chilena de Historia Valparaiso, VII, 1903) 



Dr. F. T. Delfin discusses in much detail the fishes known as Cong- 

 rios in Chile, Ophidiida of the genus Genypterus. 



In the Smithsonian Miscellaneous Collections (XLV, 1903), Dr. C. 

 H. Eigenmann defines 21 new genera of South American river fishes 

 of the group of Characinida; in advance of his monographic review 

 of the group. It is to be regretted that a closer adherence to clas- 

 sical models did not prevent the suggestion of such names as Holo- 

 shesthes, Stichonodon, Colossoma and Mylossoma. 



In Proceedings of the Zoological Society of London (1903), Mr. 

 C. T. Regan gives a review of the East Indian fishes of the genus 

 Triacanthus. In this as in many other cases it appears that the 

 species recognized by Dr. Bleeker are all really valid in spite of the 

 doubts expressed by subsequent authors with more scanty material. 



In the Proc. U. S. Nat. Museum (XXVI), Barton A. Bean de- 

 scribes a new minnow, Notropis hrimleyi (near N. coccogenis) from 

 Cane River, North Carolina.

In the Proceedings of the U. S. National Museum (XXVII, 1904), 

 Mr. E. C. Starks discusses the osteology of the berycoid fishes. 

 This group is one of especial interest because it appears earlier in 

 geological time than any other of the distinctly spiny-rayed types, 

 and It is probable that all these are described from Berycoid stock. 



Dr. Boulenger unites the berycoids with his perciformes, notwith- 

 standing the archaic characters retained by most of them. Mr. 

 Starks shows that all of them retain one hitherto unnoticed archaic 

 character which is lost in all the other spiny-rayed fishes. This is 

 the development of the bone called osbitosphenoid. 



This bone he finds in Hoplostethus, Beryx, Holocentrus. Myri- 

 pnstis, Polymixia and Monocentris. It is not found in Pempheris or 

 m Aphredoderus, which genera should be excluded from berycoid 

 The orbitosphenoid is present in the Isospondyli and 



I the ganoids.
