FISHES OF HAWAIIAN ISLANDS. 
693 
Color in spirits, light grayish above, much mottled with darker; filaments on sides of snout arising 
each from a small round light spot, contrasting with the darker ground ; under parts lighter; abdomen 
usually dark, covered with sharply contrasting white flaps; mouth and gill-cavities white, peritoneum 
jet-black. 
Stomach globular, very large, the 2 openings immediately adjacent; intestine crossing the stomach 
transversely in front, communicating with it in passing, and terminating in a blind sac, which repre- 
sents the single pyloric caecum; left liver lobe short; right long and narrow, extending to near middle 
of body cavity, its posterior end slightly hollowed out for the gall-bladder; intestine making a single 
short loop, its length but two-thirds total length of fish; the stomach contained the remains of a small 
fish, together with considerable mud, which was probably swallowed during capture of fish.
