tute a group separate and not originating from those Teleosts 
with a mesocoracoid (pp. 877 and 378). 
5. The postcoracoid process, which is so prominent a 
feature during development, represents the metapterygium 
(pp. 373 and 374). 
6. The so-called “‘interclavicle”’ of the stickleback is not a 
part of the coracoid, but arises as a separate dermal ossifica- 
tion. It is not homologous with the bone of the same name 
in the sturgeon, and should therefore receive a different name, 
e.g. infracleithrum (p. 379).
