318 EXPEDITION OF THE "ALBATROSS," 1S99-1900. 



D. M, I, 10: anal I, 10. 



This agrees ven- well with CUinther's description and figure of this species. 

 It is, however, a little more slender, and has one more dorsal ray than Giinthei- 

 gives in his description, but the same number as shown in his figure. This 

 species resembles 0. vergens Jordan & Seale in having a more slender body and 

 distinct lateral spots, but differs from 0. vergens in having a larger eye; two con- 

 spicuous canine teeth on the lower jaw and produced sjiinous rays in the first 

 dorsal fin.
