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. 
. *he body is compressed, swollen upon the thoracic 
egion, and tapering posteriorly in a very decided manner. 
he 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 
me to give the entire region an obtuse aspect. It is con- 
. “ned four times and a half in the entire length. The jaws 
: ae €qual and the gape of the mouth is oblique precisely as 
G. lepidus. The posterior extremity of the maxillary 
extends to a vertical line drawn back of the orbit, The 
* 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 comparéd to the same region 
G. lepidus, since in specimens a good deal smaller, it is 
VY double the width it has in the latter. The branchial 
res are likewise separated under the throat by a wide
