Tennessee rivers there was developed between each of the above long and 

 short bars a still shorter and narrower bar, so that the coloration here 

 consisted of whole, half and quarter bars. The Arkansas river also afford- 

 ed exact representatives of this pattern. 



Between the two patterns described every possible gradation was found. 

 The quarter bars made their first appearance between the fifth and sixth 

 whole bars. The whole bars toward the posterior end of the body in- 

 creased in width and intensity of color near their ventral limit so as to 

 give rise to an incomplete longitudinal series of lateral spots. These spots 

 were more evident in the pattern consisting of whole, half and quarter 

 bars. 



Specimens from Texas showed the bars less regularly developed with a 

 corresj^onding increase in the extent and distinctness of the series of lat- 

 eral spots. 



, A great number of specimens taken from other tributaries of the Cum- 

 berland and Tennessee rivers all showed the longitudinal series of nine, 

 almost confluent black lateral spots very highly developed, while the bars 

 had become so modified as to form quite a close network over the dorsal 

 half of the body. The young of this pattern had the spots less strongly 

 developed, and the original bars could be easily traced. 



It seems, thus, that the variations in the color patterns in E. caprodts 

 are by no means promiscuous, but that they show a serial passage from 

 one form, that consisting of alternate whole and half bars, through the 

 form consisting of whole, half and quarter bars, and having the incom- 

 plete longitudinal series of lateral spots more highly developed to the re- 

 ticulated form having a very prominent longitudinal series of dark lateral 

 spots. I was unable to discover any relation between these variations 

 and the latitude in which they occurred. 



Some (jueries relative to a supposed variety of solaxim dulcamara. By 

 E. W. McBride. 

 The books describe the flower of the common Bitter Sweet, Solarium 

 Dulcamara, as being purple in color. This, as is well known, is the usual 

 color of the flower of this plant. Some six or eight years ago, however, I 

 found in DeKalb county a specimen, which, while it in all other respects
