Five specimens M. C. Z. 29567, 2§ to 43 inches long from Perico Island.

Six specimens 23 to 33 inches long from Toboguilla Island, among coral 
in two fathoms of water. Of these five have dorsal rays 15, and six have anal 13,

The three specimens from Acapulco have general color brown, the posterior 
edges of scales darker, forming transverse lines on sides of body; faint pale spots 
on sides of head, none on front of head or nape, both lips pale; no blue line on
