FISHES OF SACRAMENTO-SAN JOAQUIN BASUN. 11835 
advance of dorsal; origin of anal under posterior ray of dorsal; margin of dorsal and anal straight; 
caudal fin longer than head, forked, the middle ray 1.6 in longest, upper lobe longer than lower. 
Lateral line decurved anteriorly, scales heavily scored. Young witha black spot at base of caudal. 
The specimens here described as conformis differ from crassicauda in having the caudal peduncle 
less deep, the caudal fin longer than head and its upper lobe longer than the lower, longer dorsal and 
anal fins, finer scales, even jaws, and heavier striation on scales. Some of these distinctions are just 
the opposite of those given by Girard. The following are his distinctions: ‘‘The general appearance 
of the fish [ Tigoma conforms] is suggestive of Lavinia crassicauda; the body is deeper and proportionately 
less elongated, the eye much smaller, and the scales larger.’’ In his descriptions, however, he says, of 
Tigoma conformis, ‘Eye moderate sized; its diameter entering nearly five times in the length of the 
side of the head,’’ and of Siboma crassicauda, “Eye rather small, subcircular, its diameter entering 
nearly six times in the length of the side of the head.’’ His comparison of the eye does not agree with 
his descriptions, and there may be a similar discrepancy with regard to the other characters.
