62. Stone on the Species of Molotlirus. 



[A Revision of the Species of Molotlirus allied to M. bonariensis (Gm.)' 

 By Witmer Stone. Auk, viii. p. 344.] 



Mr. Stone has attempted to solve the problems of the 

 number and proper names of the species of Molothrus allied 

 to M. bonariensis, and has certainly thrown some light on 

 this difficult subject. An examination of the specimens of 

 Icteridse in the Museum of the Academy of Natural Sciences 

 of Philadelphia has shoAvn that Gassings supposed Lampropsar 

 tanagrinus and L. guianensis are both referable to Molothrus 

 atronitens, Cab., and that Gassings Lampropsar cabanisi is 

 the same as what is usually called Molothrus cassini. Finally 

 Mr. Stone recognizes five sj)ecies of this group of Molothrus, 

 and proposes a new name {M. venezuelensis) for M. discolor 

 of Cassin (non Passerina discolor, Vieill.) . 



63. Suchetet on Wild-bred Hybrids. 



[Les Oiseaux Ilybrides rencontres a I'etat sauvage. Par Andrt? Suchetet. 

 Deuxieme Partie : Les Pahnipedes, Mem. Soc. Zool. France, iv. p. 109.] 



M. Suchetet describes in this memoir the hybrids bred in a 

 free state that have been recorded among the Anatidse, 

 Ijaridse, Ardeidse, and Gharadriidoe. The greater part of the 

 memoir is, as was to be expected, taken up by the Anatidse, 

 amongst which, as is well known, cross-breeding is more 

 prevalent than in any other group, except, perhaps, the 

 Gallinse. M. Suchetet records 24 cases, but we are not sure 

 that he has quite exhausted the list. In the Laridse only 

 one instance of hybridization is registered, namely Sterna 

 paradisea x S. hirundo. Amongst the Ardeidse (referred by 

 M, Suchetet to the Gruidse !) there is likewise one case, 

 Ardea cinerea x A. purpurea, and among the Gharadriidae 

 also a single instance, Hamutopus unicolor x H. longirostris.
