Girard on Fishes of California. 539 



The dorsal region above the silver band is greyish brown, 

 as also the upper surface of the head ; the silver band is 

 margined with bluish black ; the flanks, sides of head and 

 belly are light brown in the young, and silvery in the adult. 

 The fins are olivaceous throughout. 



Locality. Specimens collected in Tomales Bay. 



Plate XXIV, fig. 1, represents this fish somewhat reduced 

 in size. Fig. 2 is a view of the inferior surface of the head, 

 size of life. Fig. 3, a scale from the dorsal region. Fig. 4>

Description. This is quite a handsome species, less elon- 

 gated in its general aspect, and more fusiform in its outline 

 than G. lepidus. The largest specimen which we have 

 seen measured but a little over two inches. 



The body is compressed, swollen upon the thoracic 

 region, and tapering posteriorly in a very decided manner. 

 The greatest depth is contained about five times and a 

 half in the total length, and the least depth, on the peduncle 

 of the tail, is about one half the greatest. 



The head is obtuse, or else the snout is anteriorly rounded 

 so as to give the entire region an obtuse aspect. It is con- 

 tained four times and a half in the entire length. The jaws 

 *are equal and the gape of the mouth is oblique precisely as 

 in G. lepidus. The posterior extremity of the maxillary 

 extends to a vertical line drawn back of the orbit. The 

 eye is small, subcircular ; its horizontal diameter entering 

 about four times in the length of the side of the head. The 

 interocular space is quite broad compared to the same region 

 in G. lepiduS) since in specimens a good deal smaller, it is 

 nearly double the width it has in the latter. The branchial 

 fissures are likewise separated under the throat by a wide 

 isthmus.
