A. 29; scales 7-37-5; depth 3. 



In one the interorbital is distinctly less than the diameter of the eye, 

 in the other just equal to it; the maxillary about equal to the eye, which 

 is 2f in the head. The pectorals extend a little bej'ond the origin of 

 the ventrals. 



These specimens and the next one have much larger ej-es than speci- 

 mens of a^neus from Mexico. I am not able to say definitel}' what the 

 name of the variet}^ should be. Specimens collected b}^ Meek at Mont- 

 zorongo and labeled »neus belong in part to seneus and in part to this 

 large-eyed variet3^ 



No. 44946. One specimen. Veracruz, Mexico, collected by A. L.

•A. 31; scales 8-38-7; depth 2f; eye 2f; maxillarj^ not equal to the

1 doubt very much whether specimens of yasc^W'^s and nie.vicanus^ 

 rtitilus^ (Fr.'^ted/'/\ and «^??(??i.s', if freshh" collected, similarly preserved, 

 and mixed in one heap, could be separated specifically.
