mihi. Monomitopus agrees with NeohytJdtes in every particular, except 

 that each ventral fin consists either of a single ventral ray (M. 

 nigripinnis) or of two rays firmly fused throughout their extent {M, 

 conjugator). 



Bicrolene, Goode and Bean. 



In the definition of this genus the branchiostegals should be stated 

 as eight. Paradicrolene, mihi, then becomes a synonym of Dicrolene. 

 It seems to me almost doubtful whether JDicrol&ne (and Pteroidonus) 

 should be kept separate from Neohythites. For there is an undoubted 

 Neohythites {N. pterotus) in which the pectoral rays, in the male at any 

 rate, are much produced, although none of them are strengthened and 

 entirely independent. 



Dicrolene intronigra, G. and B. 



I have compared Indian specimens with one from the North Atlan- 

 tic, and the only difference is that, in the former, the inside of the mouth 

 and the fins are much blacker. 



There are 8 branchiostegals in both. 



GlyptopMdium, Alcock. 



In the definition of this genus the ventral fins should be stated as 

 consisting of either one or two rays each : the lateral line should be 

 stated to be absent. 



Lamprogrammus, Alcock. 



To the definition of this genus it should be added that an air- 

 bladder is present. 



Family Macruridse. 



Macrurus (Mystaconurus) heterolepis, Alcock. 



This species is very probably identical with Macrurus {Mystaconurus) 

 cavernosus { = Bat]iygadus cavernosus) Goode and Bean, from the Gulf of 

 Mexico, 227 fms., a specimen of which I have examined. 



Family Stomiatidae. 



Thaiimastomias^ Alcock. 



Prof. Chr. Liitken (K. Dansk. Vid. Selsk. Skr. 6 Reekke, Nat. 



Math. Afd. VII. 6, 1892, p. 281) considers Thaumastomias to be identical 



with Photostomias (CoUett, Bull. Soc. Zool. France, XIV. 1889, p. 291), 



notwithstanding that the dentition and the whole structure of the
