Conger neoguinaicus, Bleekcr (Act. Soc. Sc. Indo-Neerl. vi. 

 Nieuw Guinea, p. 22), or Ophisoma neoguinaicum, Bleek. (Atl. Ichth. 

 Mur. p. 28), is founded on an example so badly preserved that no 

 really distinctive characters can be pointed out. It is possible that 

 it is identical with C. habenata.

Myroplds heierognatJms, Bleeker, Act. Soc. Sc. Indo-Neerl. v. 

 Japan, v. p. 9, pi. 3. fig. 1, is another name given by Dr. Bleeker 

 to a young congroid fish, in bad condition, from Nagasaki. The 

 character by which, perhaps, it may be recognized is the great 

 length of the tail (body=2 inches, tail=3| inches). On the other 

 characters assigned to this fish by its original describer, Dr. Kauji 

 has founded a new genus, GnatliopMs (Aale Hamburg. Mus. p. 7) ; 

 but Dr. Blocker states (Atl. Ichth. Mur. p. 29) that his original de- 

 scription is not what it ought to have been, and that the fish is a 

 second species of Uroconger. I cannot agree with him in this last 

 conclusion, the fish having quite a diff"ercnt dentition ; it is, in fact, 

 a CongromurcEna, and very closely allied to C. liahenata.
