I. INTRODUCTION 



The present status of heterogenic hybridology in animals 



Experiments in hererogenic hybridization of animals have 

 been performed largely upon two groups, Echinoids and Teleosts. 

 A much larger amount of attention has been paid to the former 

 than to the latter group, although it now seems certain that the 

 Teleosts in a number of important respects are more favorable 

 than the Echinoids for this kind of work. The list of investi- 

 gators who have contributed to the literature of hybridization 

 among the Echinoids is imposing, including as it does such names 

 as Boveri, Seeliger, Morgan, Vernon, Driesch, Delage, Stein- 

 bruck, Loeb, Doncaster, Peter, Fischel, Herbst, Godlewski, 

 Kupelwieser, Hogedoorn, King, Moore, Tennant, McBride, 

 Fuchs, Debaisieux, Shearer, and DeMorgan. Only a few, largely 

 Americans, have studied hybridization in Teleosts and the 

 work has been comparatively superficial. Only the following 

 seven or eight investigators have contributed to this field: 

 Appellof, Bancroft, Hertwig, G. and P. Loeb, Moenkhaus, Mor- 

 ris and Newman. It is my conviction that had the same amount 

 of attention been applied to Teleost hybridization as has been 

 given to that of Echinoids, we would have a vastly better under- 

 standing of the truth about heterogenic hybridization phenomena 

 that we now have.
