formed of one very slender spine and five rays ; the pectorals of 

 sixteen rays ; the second dorsal is higher than the first, its fourth, 

 fifth, and sixth rays being the longest, and equal to the length of 

 the snout ; the others become shorter as they go backwards ; the 

 anal is of the same form. The first dorsal is situated on a line 

 that would cut the end of the pectorals ; the second is inserted 

 at a distance from the first, equal to the space between the 

 beginning of the first and the end of the operculum. The pec- 

 torals are a little longer than the ventrals. 



The upper parts are of a slatey grey ; the lower white ; the eye 

 is silvery ; the second dorsal and caudal are of an obscure yellow ; 

 pectorals white, as are also the ventrals and anal ; sometimes a 

 rather large, irregularly-rounded black spot on the upper lobe of 

 the caudal, near its extremity 



Common in the months of May, June, and July ; it attains 

 2 feet in length. The fishermen sometimes call it Skip Jack, but 

 that name is more particularly applied to Temnodon Saltatar. 

 It is considered equal to Spliyrana Novae Hollandice for the use 

 of the table.
