A comparison of specimens sent by Doctor Liitken to the National 

 Museum, No. 11960, from Lagoa Santa shows that two of the speci- 

 mens have a complete lateral line and two have it interrupted. They 

 represent, respectively, 'Liitken''s Jusciatus and interru2Jt us. There is 

 no doubt but that these specimens are specifically and genericall}' dis- 

 tinct. The latter is a Heinigraiiiinus and differs, aside from the generic 

 characters, in the proportions and color. In 1894 I recorded speci- 

 mens of H. interruptiLS from Rio Grande do Sul, Brazil. A reexam- 

 ination of these in connection with Liitken's specimens shows that they 

 are not specifically identical with Liitken's specimens, and probably 

 represent two distinct species, hoidengeri and lutkeni. Liitken's speci-
