 IHafjuosis. 



Tetraodontoidea with the medifrontines separated Irom tlie supraor 

 cipitine by the intervention of the sphenotics, which are connected to- 

 gether and laterally expanded but short, the prosethnioid prominent 

 above, enlarged and narrowed forwards, the vertebra* in normal niim 

 ber (about 8+9), the head con)pressed and with a projecting attenuated 

 snout, and the dorsal and anal fins short and ]>aucira(liat»'. 



CHONEKHINID.E. 



Diagnosis. 



Tetraodontoidea with the medifrontines separated from the supraoc- 

 cipatine by the intervention of the sphenotics (postfrontals), which are 

 much enlarged and assume a quadrangular form, the prosethmoid little 

 l)rominent to view and very short, the vertebric in increased number 

 (12 + 17), the head wide and with a blunt wide snout, and the dorsal 

 and anal tins long and multiradiate (I) 32-38^ A 28-.'32). 



VI. 



The genera of Tetraodontoidea certainly very much needs revision, and 

 many species yet require to be referred to their proper systematic places. 

 The paucity of the material in the National Museum prevents my un 

 dertaking the task at present. Mr. Barton IJean, the assistant curator 

 of fishes, to whom I am indebted for efforts to bring together the mate- 

 rial, has only been enabled to find thirty-three species. There are skel- 

 tons of twelve siiecies, viz. :
