Remarks. — This peculiar, deep-bodied fish has been known hereto- 

 fore only from off South Africa, whence it was described by Gilchrist 

 in 1922. The three Philippine examples recorded here were obtained 

 by the Albatross many years before Xenolefidiclithys was discovered 

 in South Africa. The figure of one of these specimens, here repro- 

 duced as plate 7, was made by K. Ito on board the Albatross during 

 the cruise on which the fishes were captured. 



There is no doubt whatsoever of the identity of one of Mowbray's 

 paratypes of Grammicolepis squamilineatus with this species. The 

 fact that this specimen was not distinguished by Mowbray from his 

 other examples, which are plainly Grammicolepis.^ is evidence of the 

 remarkable similarity of the young of the latter genus to Zenolepi- 

 dichthys.
