The National Museum has skeletons of T. Ilomkcnii ami T. uhlonfjun, 

 and also of T.pardalis (Temm. and Sch,), and these indicate a genus 

 distinct from Lagocephalus to which the^' would be generally referred 

 on account of agreement in the nasal structure. But further they indi- 

 cate that there is considerable dilference between T. ohlmu/us and T.jxir- 

 (lalis oil the one hand and T. Jlonckenii on the otlier. I reserve tlie 

 consideration of these diti'erences and the noinenclaturi- for a fiitun'

The E. maenlatnm was not described. 



In 18G5 Bleeker, in a review of Bibron's system, conclud*-*! lliat 

 EphippUtn was the only genus with which Bibron enriched science and 

 gave the following note on E. mavulatum:

In 1S70, Giinther recogni/.e<l in the genus *' Tetrodon" a section ba.se<l 

 on the Tdtaodon (/ittti/cr of Heiiiirtt, to which he gave the new name 

 Hemiconiutiifi. The section w:is d* lined in the foUowiiig terms:

The notices of Bibr.-n and Bleeker of Kphi])pwn were completely 

 overlooked and ignored in the synonymy of the species, section, and 

 genus Tetrodon. Ilemimnialus is in fact a s.Mionym of f^phippion, and 

 iu order to learn the essential characters of T. gutiifer, such a.s the
