therefore, the niinie given by Bleeker (heiiijr likewise not |>n'(»cciii)i«><l) 

 must be Jiceeptcd. 



The liatiii form of the generic umnc, Xenoptcnix, was not given till 

 1857, when Hollard used it in his memorable " I^tudes siir les Gyni- 

 Dodontes," the first memoir in which the genera of a large groiiji ol 

 fishes were diagnosed b^' details drawn from coini)arative anatomy. 



A summary of the facts thus made known is embodied in tin* follow-

Inasmuch as Bleeker himself corrected Chonerhinos to ChonerhinuK, 1 

 have accepted the latter ; lam tempted to still further change the 

 name to Clionorhinus (in analogy with /wwoef^es), but for the present at 

 least forbear to do so. 



In 1S30-1841, Johannes Midler, in a note to tlu' tiiiid i);tit ol his 

 Vergleichende Anatomic der Myxinoidcn,* set ai)art a section of tin' old 

 genus Tciraodon, as follows: 



Andere Tetrodon haben keine Spur von Naslucheru nnd un dicserStolleeiuer liaut- 

 artigeu trichterfonnigen Tentakel, Chelonodoii, Noli. 



No species was mentioned in connection with this notice. 



The diagnosis is apidicable, so far as it goes, to ('liinurlntius, and il is 

 (juite likely that it was based on that type. It has, however, been ac- 

 eei)ted for a section including the *' Trttodon putoai" " T. riridipumtiituH,"" 

 and "2'. Waandcrfiii;' a^ by Dr. Ciinther ((\it. Fishes \\. .M., v. s. pp. 

 272, 288), defined as follows : 



C. A simple, non perforate nasal cavity with n fringwl <«l«e. Uody Hpiity: Ckelo- 

 iiodon, Mil II. 



As I have none of the species mentioned I hold opinion in abeyance.
