 ing color markings: In spirits, color dark brown, shading into 

 black on the posterior half of the body; the body covered with 

 minute white dots, like pin points, yellow in life, none of the dots 

 are as large as the head of a pin, these dots very numerous on the 

 anterior third of body and head, but gradually decreasing in num- 

 ber posteriorly, until on the posterior half of the body they are few 

 and widely scattered; belly and throat yellowish white, being 

 powdered with yellowish dots; in addition to the above there is on

 tical, band-like arrangement; fins colored similar to body, caudal 

 with a narow white margin.
