The fourth ray bears dorsally a series of recurved hooks, which are 

 protected by the fifth. At the tip, the organ bears on the under side 

 two antler-like processes. These bear a prong near their tips. 



Girardinus and Glaridichthys of Cuba differ from each other by the 

 presence in the latter of an inner series of teeth. Phalloceros differs 

 from Glaridichthys by the lack of retrorse hooks on the posterior margin 

 of the anal and the presence of the terminal antler-like processes. 

 Reference should be made to the excellent figure of the generic char- 

 acters, given by Eigenmann, loc. cit., p. 431, fig. 7. The genus up to 

 date has remained monotypic.
