No. 20,446, A. N. S. P., type of Z. brachypterus Cope. Trinity 

 River, Fort Worth, Texas. E. D. Cope. 



Besides a large series of local material from New Jersey to Vir- 

 ginia are specimens from Big Cypress in Lee County (Baynard), 

 Florida; Devil's River (Pilsbry), Texas; Lake Superior at Pequaming 

 in Brayon County (M. Hebard), Michigan. This species is very 

 abundant in southern New Jersey, Delaware, Maryland and Virginia, 

 coastwise. Although Dr. Regan separates Heterandria holbrookii 

 Girard and H. patruelis Baird and Girard as distinct species, I feel 

 convinced they are not separable. The amount of variation, even 

 in New Jersey examples, is sufficient to include the limitations he 

 gives, as well as permit still greater latitude. Many aquarium 

 specimens are marked with large black blotches, others are pale 

 and immaculate.
