All the specimens from the first seven localities show the dark snborbital spot 
very distinctly. All the specimens from Sims Bayou are very pale and there is no 
snborbital spot in any of them, but all the fishes gotten from this place present a 
bleached appearance, due, no doubt, to the character of the water in which they were 
found, which was a muddy and foul pool left by the drying up of the greater part of the 
stream. Of the specimens obtained from Dickinson Bayou, 4 show the spot while the 
others are plain. All these specimens were also quite pale. The 15 specimens from 
San Antonio are quite dark, and the majority show the dark suborbital spot. The 
majority of the numerous specimens from Hew Braunfels show the spot, though in 
some it is quite faint and in others it is wholly absent. All these specimens are quite 
dark and resemble those from San Antonio. Those from San Marcos are rather pale 
and but few of them show the suborbital spot. 
There do not seem to be any good reasons for separating G. liumilis from patruelis , 
even as a geographical form. 
In many of the female specimens from San Antonio and Hew Braunfels the em- 
bryos are quite large, fully J inch in length, showing that the species produces its young 
in midwinter in southern Texas. Specimens collected by Dr. Hugh M. Smith, at St. 
George Island, Maryland, July 1, contained immature eggs, while others collected at 
the same place by him August 11 contained young apparently ready for extrusion. 
31. Mollienesia latipinna Le Sueur. 
One specimen of this attractive species was taken at Corpus Christi, 2 at Gal- 
veston, 42 at Dickinson Bayou, and 1 from Hunter Creek, near Houston.
