anal spine, the much more distinct dark lines, the less nearly vertical 

 mouth, the hack more steeply arched, the darker color of the gill cavity. 

 In some cases the direction of the rows of scales on the hack is more 

 nearly vertical, but in this there are great variations. West coast of Mex- 

 ico and Central America, from Sonora to Panama ; not rare on sandy shores. 

 Length 4| to 6| inches. Described from numerous specimens from San 

 Juan Lagoon, Sonora, and from Panama. (accUvis, steeply ascending,

 slender, the longest li in head; least depth of caudal pedunch' 3 in 

 head. Scales as in L. acclivis, excepting that in our specimens the rows 

 above the lateral line are rather more horizontal and therefore fewer in 

 number than in some specimens of L. acclivis. Origin of spinous dorsal 2 

 in origin of soft dorsal and If in head ; third dorsal spine If in head ; 

 second anal spine 1|- in head, reaching to tip of longest soft ray; ventrals
