The .species is represented in the Jouy collection by a single indi- 

 viduiil (No. 4:!t7o7, LT.8.N.M.). which is very similar to the typo. It 

 is from otf Yokohama, })robably from the same type locality of Misaiii.

76. HOPLOBROTULA ARMATA (Schlegel). 

 (Plate XXXVIll.) 

 {Brohdn (irmafa Schlegel. ) 



Althoug-h this species is not represented in the Jouy collection, it 

 will lie of interest in connection with the genus and species just men- 

 tioned ( Watasea shicolrt) to record the character of a fine specimen 

 403 mm. long obtained at Nanaiira, in Boshu, near Misaki. It was 

 presented by the Imperial University of Japan to the Stanford Uni- 

 versity collection. 



The genus Iloplolyrotula differs from Neohythites^ Watasea^ and 

 Sh'emho in having three strong opercular spines, the maxillary and 

 parts of the head naked, and the posterior upper part of the maxillary 

 free from the suborbital. The ventral lins are bifid. 



Head, 4| in length; depth, 5i; eye, 5| in head; snout, 4,';; maxillary, 

 l,'',; 1)., cS(5; A., 74; P., 20; scales in lateral line, 112; between lateral 

 line and insertion of dorsal, 9; between lateral line and insertion of 

 anal, 27. 



Interorbital space convex; its width equal to length of snout. Jaws 

 ecpial. Snout blunt; almost truncate. Maxillary extending poste- 

 riorly far beyond the eye; the upper edge not covered by preorbital 

 for the entire length; the distal end broad; the posterior edge slightly 

 concave. Lips rather thick; their surfaces covered b}' minute epider- 

 mal flaps. Jaws, palatines, and vomer with minute, sharp, firmly 

 embedded teeth in villiform bands; a toothed area extending from 

 near tip of tongue to posterior part of phar3'nx; roof of pharynx with 

 toothed surfaces similar to those of jaws. Gill-rakers on first arch,
