NO. 2149. JAPAXESE MACROVROID FISHES— GILBERT AXD HUBBS. 207 



orbit 3.3 in head; nostril flap shorter; 4 to 6 spinules on scales of 

 body; an additional naked area, as in T. senflpeUis,'^ the Hawaiian 

 species, located at the upper angle of the preopercle ; second dorsal 

 spine half as long as head; base of first dorsal 1.3 in interdorsal 

 space. A still smaller specimen, 131 mm. long, 26 mm. to anus, also 

 from station 4971, has only 1 to 4 spinules on the scales; the teeth 

 coarser ; and the opercle with a sharp but weak spine at the end of 

 each limb. 



Giinther's short description evidently errs in stating that the sec- 

 ond dorsal begins immediately behind the first, and the mouth is 

 probably described and figured too small. 



T. villosus differs from T. sentipellis, the Hawaiian species, in 

 having the gular membrane scaled, and in certam proportions, as 

 indicated in the following table : 



Tabic of measurements in hundredths of length to anus. * 



30. CETONUEUS ROBUSTUS, new species. 



Plate 11, fig. 2. 



The genus Cetonurus is fully defined in the key to the subfamilies 

 and genera. 



C. rohustus is apparently closely related to C. crassiceps (Giin- 

 ther),5 Imown from a single specimen taken by the Challenger north
