Lepidoptera of Buffalo.— E. P. van Dune publishes 1 a list of 



the Macro-Lepidoptera of the vicinity of Buffalo, N. Y. In all 777 

 species are enumerated. In the arrangement W. H. Edwards is 

 followed for the butterflies and Aug. Grote for the Moth- 

 the Sphingidse and Agrotida?, where J. B. Smith has been followed. 

 and the Phycidse, which are arranged according to G. D. Hulst 



The Position of the Solenoconchse.— Dr. L. Plate, 2 after a 

 brief account of the structure of Dentalium, Siphonodentalium. Bip- 

 honentalis and Cadulus, concludes that the.-e forms -how more rela- 

 tionship to the Gasteropods than to the Lamellibranclu in "(1) the 

 unpaired shell; (2) the radula ; (3) the jaws; (4) the tentacles, which 

 can only be homologized with those of tli.- ( rastemp<.d> : .', ■ the body

 of an ancestral form and especially the ancestors of the Cephalopod ' 

 is supported [upon the supposition that] the arms of the cuttle fishes, 

 as appendages of the head, .are homologous to tentacles of the Soleno- 

 conchae. It appears to me that recently the pedal nature of the
