80 MEMOIES OF THE CARNEGIE MUSEUM 



second supra-anal above (or slightly in advance of) the fourth ventral, nearer 

 the fourth ventral than the upper supra-anal, which is above the anus and 

 scarcely in contact with the lateral line. Anals 7 + 10, small, close-set, in a 

 straight line, the anterior not lower than the others; the last antero-anal is 

 above the thirteenth anal ray, the fifth postero-anal over the last anal ray. 

 Posterolateral somewhat behind the vertical from the last antero-anal, immedi- 

 ately below the lateral line. Precaudals obliquely placed, the second higher 

 and separated from the first by a wider interval than that between the anal 

 photophores. 



The six large luminous plates on back of caudal peduncle are very con- 

 spicuous, as they are lustrous white on a black background. The scales are 

 lost and the integument partly gone, but the general color seems to have been 

 dusky, blackish at the base of the fins. 



Myctophum hoops Richardson is probably a synonym of M. huniboldti. The 

 figure of the type gives thirteen rays in the pectoral fin, the description fifteen, 

 both numbers within the known range of huniboldti.
