 » The stomach is an elongated cylinder, exceeding doublé the hngth of the head. lt was 

 » filled wilh crustacea (shrimps and crabs). The lenght of the sijnple intestinal canal is 

 » somcwhat less llian V 3 of the total length of the eel. The air-vessel is elongated, spindle- 

 »shaped, of a silvery white, firmly adhering to the spine ; the length is about 1 '/ 2 of the 

 «head; it occupies nearly the postcrior half of the abdominal cavity. The ovaries extend 

 » from the cavity of the tail to the heart; they are firmly adhering to the sides of the spine, 

 » wilh their f ree, lower margins festooned or puckered; the ova are minute, of a whitish

» The first 9 branchiostegous rays of the right side are sepnrated from the rest by an 

 » interval, and pass above the branchiostegous rays of the lef t side. The succeeding 16 right 

 » rays parlly cover and pass beneath those of the left side. The rays of the left side are 

 » all closely united. On each side, three rays are bipartite, so that counted from the ex- 

 )) {remilies of the rays the number appears to be 28. But, counted from the origin, there 

 r, are on each side 25 rays.
