Genus INU, new genus. 



This genus resembles Luciogohins and is no doubt related to it. 

 It differs principalh^ in having scales. 



Body short, with a deep caudal penduncle; head large, broad, the 

 muscles of the cheeks and sides of the head greatly developed, 

 bulging upward beyond the occiput ; eyes directed upward and for- 

 Avard; jaws about equal, the cleft of mouth extending back^vard far 

 beyond ej^es. Teeth simple; an outer row of enlarged ones, within 

 which is a narroAv band of minute ones. Tongue notched at tip. 

 Gill-openings restricted to the sides. Shoulder girdle without proc- 

 esses. Pectorals without filamentous rays, ventrals present, well 

 developed and united in a round disk, the anterior edge of which is 

 greatly thickened; spinous dorsal absent; soft dorsal and anal in- 

 serted opposite each other, their points of origin near middle of body. 

 Small cvcloid scales on posterior part of body ; head naked. A small 

 anal papilla. On the back, before the dorsal is a slight median de- 

 pression, on either side of which is a row of minute, oblique plicfp, 

 these being preceded by a slight median ridge. These peculiar plicpe 

 are also present in Litciogohius, Clariger, and Expedio^ and they are 

 sliglitly developed in Asfrahe. 



The genus is known to include two species of voracious-looking 

 little gobies found in the pools at Misaki.
