preoperculum with rather smaller scales, those of interoperculum smaller 
still. Margins of orbit scaleless, the scales of occiput, which are rather 
small, advancing to a point very slightly in advance of une anterior or- 
bital margin. Cheeks, jaws, and fins scaleless. 
Lateral line appreaching gradually nearer to the dorsal outline toward 
the posterior ‘portion of the body, and running a little above the center 
of the caudal peduncle; pores simple. 
Color, in alcohol, dark brown on snout and cheeks, fading to silvery 
on sides and rest of body; behind the pectorals there are traces of 
golden reflections. 
On the orbital margin, just above the posterior nostril, there is a 
tubercular projection of the bone. ; 
Several specimens of this species were sent from Magdalena Bay, 
Lower California, by Mr. W. J. Fisher. They were unfortunately in 
rather bad condition, so that the tips of the rays of the soft dorsal and 
anal are broken off both in the example described and in others which 
were carbolized and dried. 
One of the examples is in the National Museum, Washington, D. C. 
This species should probably be placed in the genus Calamus Poey, 
which includes also the Pagellus calamus of Cuy. & Val., but as I have 
not Poey’s work at hand I leave it in the Linnzean genus Sparus.
