As I mean, that the last word in this question is not 

 yet spoken , I have given this abridgement of the enorm 

 material (a total of 143 ex.) in the Leyden Museum 

 and the few remarks on some individuals, in the firm 

 expectation, that the ichthyologist, who in future will 

 make the so desired , more elaborated monograph of the 

 Gohiidae , than that of Bleeker (Arch. Neerl. 1874, T. 

 IX, p. 289), shall use in the first place the Leyden col- 

 lections. 



I agree with Günther (T. Ill, p. 23) that G. unicolor E. 

 et V. H. is a distinct species ; the type-specimen is preserved 

 in the L. M. sub N". 1819. 



7. Eleotris aporos Blkr. 

 Günther, Cat. of Fishes, T. Ill, p. 109. 



N». 5177. 1 Ex. Length 155 mM. 



The type-specimens of this species, founded by Bleeker 

 (see Nat. Tijds. Ned. Tnd., T. VI , p. 59), are preserved 

 sub N". 5178, 6 ex. Sindangole, Halmaheira. 



8. Eleotris Hoedtii Blkr. 

 Günther, Cat. of Fishes, T. Ill, p. 110, 



NO. 5179. 2 Ex. Length 138 and 157 mM. 



Sub N". 5180 are preserved 17 ex. from East Indian 

 waters , Coll. Bleeker ; among them the type of the species , 

 from Amboina, long 161 raM. (see Nat. Tijds. Ned. Ind., 

 T. VI, p. 496). 



After Bleeker (Versh Kon. Ak. Wet. Amst. 1877. 2<ie 

 Keeks, T. XT, p. 27) E. aporos and E. Hoedtii belong to 

 the genus Ophiocara Gill (Proc. Ac. nat. Sc. Philad., 1863, 

 p. 270), as well as E. ophiocephalus K. et v. H. (type sub 

 N^ 2052) and E. porocephala C. V.
